June: handset sell-through stalls on wait-and-see attitude
Summary Rural subsidy programme has helped TV sales, but done little for handsets. Sell-through of handsets (both branded and white-box handsets) for 2Q09 has been below the channels expectations, due to consumers adopting a wait-and-see attitude amid the launch of 3G services in China. The rural subsidy programme has been neutral for rural handset demand, according to channel checks made on our recent visits to China. Demand for TVs picked up for April, underpinned by the subsidy programme (which took effect nationwide on 1 February 2009). TVs have been the second most-popular item (after refrigerators) under the subsidy programme, according to the Ministry of Commerce. The acceleration of the migration from CRT TVs to LCD TVs in urban areas also contributed to the pick-up in demand. For PCs, 2009 full-year shipments are likely to register low-single-digit growth, compared with a 15% YoY rise for 2008, according to the PC vendors and distributors we met with recently. Subsidies for PCs in rural areas took effect on 1 April 2009, but PC demand from rural households is likely to be low due to Internet connection fees/quality, and PC-literacy issues, in our opinion. Markets expectations have been lowered. We believe the markets expectations of demand for technology products have been reset to lower levels following the sharp downward revisions to forecasts at the beginning of the year. Future forecast revisions are likely be upward, in our opinion. Stock picks. In this, the inaugural edition of China Tech Tracker, we recommend that investors sell Lenovo Group (Lenovo) (992 HK, HK$2.95, 4), as we believe its share price has run ahead of the fundamentals, the contribution from rural households is likely to be minimal, and competition in urban areas could intensify. Around the region, we think TFT-LCD makers should benefit from Chinas rural and upcoming urban subsidy programmes. LG Display (034220 KS, W32,000, 2) is our pick.

At the end-market visits to retail corners
China Mobiles mobile-broadband netbook offers This month, we visited shops in Shanghai and Nanjing. There were prominent displays of offers for netbook and TD-SCDMA mobile broadband service bundles by China Mobile (941 HK, HK$78.70, 2), with netbook prices starting from Rmb2,599 (see the following table) with a wide choice of brands Lenovo, Dell, HP, Samsung and Acer, Tongfang, and Haier.

No awareness of Windows 7 launch
With respect to the launch of Windows 7, PC vendors have not yet briefed their channel partners about the arrangement for the operating system (OS) upgrade coupons. Some salesmen in the stores claimed they would be able to upgrade the system for free once the OS was available. We think the launch of the OS is unlikely to drive any significant replacement demand in China. We saw some displays for LED backlight TVs by various brands, including Skyworth and Hisense. The retail price of a 42 back-lit LED TV from Hisense was Rmb12,999. In Shanghai, we came across a potential customer considering buying a 55 Hisense LCD TV for Rmb15,999, to replace a rear-projection TV bought five years earlier. 3G handsets were not widely available in stores in June. We were offered only one WCDMA handset model, the W715 from Sony Ericsson. We did not see any TDSCDMA handsets in the shops. In general, the salespeople were confused and had little knowledge about the three different 3G technologies and the corresponding 3G handsets.

Investment ideas
Lenovo (4 rating, six-month target price: HK$1.47)
In China, rural PC demand should be minimal, and competition in the urban areas is increasing as the foreign brands and Taiwan players are building up their presence rapidly in the retail channel, in our view. We expect the forthcoming data points from IDCs and Gartners 2Q09 PC market share estimates (due to be released on 16 or 17 July) to continue to show that Lenovo is losing market share in the PC market globally (note: in 1Q09, Lenovo PC shipments fell by 8% YoY, compared with an 11.6% YoY increase for Toshiba, a 6.8% YoY rise for Acer and a 2.9% YoY increase for HewlettPackard), as there has been no meaningful pick-up in corporate demand for PCs, which accounts for more than 50% of Lenovos revenue. Trading at 30.1x on our FY11 EPS forecast of US1.26 (Bloomberg consensus: US1.30), Lenovos share price has run well ahead of the fundamentals, in our view, and is trading at a significant premium to the average for its industry peers of 10.7x.
LG Display (2 rating, six-month target price: W38,000)
Given LG Display's higher utilisation rate than those of its peers and an increase in market share in the TV segment, we expect the company to record a profit from 2Q09, one quarter ahead of the markets expectations. Chinas urban subsidy programme should increase demand for 37 LCD TVs and should benefit TV panel makers in 3Q09. About 10-15% of the companys TV sales are from the China market. We expect the stock to be re-rated to a mid-cycle PBR of about 1.5x over the next six months.

Topic of the month

Rural subsidy programme
Rmb4bn sales for May under the subsidy programme The nationwide programme, which subsidises up to 13% of the retail price of home appliances for rural households, took effect on 1 February 2009 for TVs, washing machines, refrigerators, and handsets, and 1 April 2009 for PCs. According to the Ministry of Finance, monthly sales of home appliances under the programme were Rmb4bn for May, up from Rmb1.3bn for April. The shops that we visited said they had recorded an increase in sales volume of 20-30% for June compared with the same month in 2008. Refrigerators and TVs have been the two most popular products for rural households, followed by washing machines. Purchases of handsets under the programme have been minimal, according to our checks at retailers. The incentives programme has been better for big-ticket items, including TVs and refrigerators (note: TVs and refrigerators have retail-price caps of Rmb3,500 and Rmb2,500, respectively, compared with Rmb1,000 for handsets). A total of 4.4m refrigerators, 2.4m TVs and 1.0m washing machines have been sold since the subsidy programme was launched on 1 February. PCs are included in the second group of items to qualify for subsidies. A government tender was completed in mid-May, and a total of 17 vendors qualified. We visited a Suning store on the outskirts of Nanjing where 15% of the sales were to rural households. According to the manager, the shop would offer PCs in July, but he expected demand to be moderate compared with that for TVs and other home appliances given Internet connection quality/fees issues and a lack of computer literacy. This echoes our views on the limited benefits of the programme for Lenovo. Domestic brands have a major advantage, in our view, due to their extensive distribution networks in rural areas. The networks of Gome Electrical Appliances (Gome) (493 HK, HK$1.94, Not rated) and Suning are mostly in the tier-one to tier-three cities and do not offer meaningful coverage of the rural areas for overseas brands. Suning has had about a 2% market share of the sales to rural households year-to-date, according to the companys president.

Urban replacement subsidy programme
We expect the programme to stimulate up to Rmb20bn worth of replacement demand On 19 May 2009, the State Council announced a home-appliance replacement subsidy programme for certain regions. The details of the programme and the date from which it takes effect have yet to be announced, but we expect to see a meaningful impact from September 2009. The government has allocated a budget of Rmb2bn (about US$300m) to subsidise up to 10% of the purchase price of TVs, washing machines, refrigerators, PCs and air-conditioners. We have heard talk in the market that there will be a maximum subsidy amount of Rmb400 per item, with no price cap for home appliances. In this case, brand vendors would have to price products such as PCs and LCD-TVs at about the Rmb4,000 level to maximise the benefit of the subsidy. We expect some consumers to defer making a decision on replacing their appliances pending the implementation of the programme, which might affect near-term demand in the urban areas. Over the next few quarters, we expect the programme to trigger about Rmb20bn worth of replacement demand for home appliances in the urban areas, which compares with the monthly home appliances sales value of Rmb4bn under the rural subsidy programme. In our opinion, extending the initiatives to cover the entire country should take time, given the back-end logistics issues, including the recycling capability and the environmental impact.

Negative near-term impact as consumers defer their replacement decision
We think nationwide implementation is unlikely over the near term

Sector outlook:
No significant rebound in 2Q09. At the distribution level, Digital China (861 HK, HK$5.43, Not rated), Chinas largest IT-product distributor, indicated that there has been no significant pick-up in revenue for 2Q09 for its distribution business unit. Negative same-store sales (SSS) growth for 2009. At the retail level, 1Q09 revenue rebounded from the trough for 4Q08. Retailers, including Gome and Suning, are guiding for negative SSS growth for 2009 due to falling average selling prices and reduced demand. Focus on IT, handset and digital products increasing. Gome has said that its market shares in the PC and handset product markets are still low, and it is aiming to increase these. Co-operation with Dell is one of the steps the company has taken that should lead to greater competition for the domestic brands, in our view. Inventory. Retailers have indicated that inventory is still high for air-conditioners, but low for refrigerators and washing machines. Inventory is rising for handsets, and normal for TVs and PCs.

PC demand from rural households. The PC vendors that we met were not optimistic about the PC demand from rural households, as PCs are not at the top of the wish-list of the rural households. We forecast PC demand under the subsidy programme to be about 1m units for 2009, or about 3% of the total PC shipments in China for the year. Ramp-up in netbook shipments. Netbook shipments should increase at a greater rate than that for the whole market given the low base for 2008 and aggressive subsidies by operators of netbooks as part of their efforts to promote mobile-broadband services. In China, netbooks accounted for 15% of total notebook shipments for 1Q09, up from 13% for 4Q08, according to Gartner. Market expectations reset to a low base. The markets expectations for the PC market have been revised down substantially. Gartner currently forecasts a 2% YoY decline in China PC shipments for 2009. We think future forecast revisions will be upward, on the back of the stimulus measures.

Migration to LCD TVs is accelerating. LCD-TV shipments exceeded CRT shipments for 1Q09. We expect the migration to LCD TVs to accelerate. For Skyworth, LCD TV sales accounted for 77% of its total China TV shipments for April 2009, up from 25% for the same month one year earlier. Domestic TV players to continue to dominate the rural subsidy programme. TV shipments for March were 382,000 units. Domestic players dominate, with a 98% market share accounted for by six domestic players for March (Changhong 19.7%, Hisense 18.4%, Skyworth 18.0%, Haier 16.1%, TCL 13.2%, and Konka 12.9%). We forecast TV sales under the rural subsidy programme of 4m units for 2009 (equivalent to about 10% of the total China market).

Weak end-market demand in 2Q09. End-market demand was weak amid a reduction in net addition of mobile subscribers for April and May. This was in line with our checks with Gome, which said that handset sell-through (all branded handsets) in 2Q09 was below expectations. The white-box handset market was also slow for May and June, according to our checks with Longcheer, a Shanghai-based handset design company. End-market might recover in 3Q09. A wait-and-see attitude amid the launch of 3G services in China is another reason for the slowdown in handset sell-through in 2Q09, in our opinion. We expect a moderate recovery in handset demand in 3Q09, as the three mobile operators step up their promotional efforts, 3G network coverage and quality improves, and more 3G handset options become available. Rural subsidy programme is irrelevant to rural handset demand. The rural subsidy programme is neutral to rural handset demand, according to our channel checks.

SAFETY PRECAUTIONS

IMPORTANT SAFETY NOTICE

Many electrical and mechanical parts in this chassis have special safety-related characteristics. These parts are identified by in the Schematic Diagram and Replacement Parts List. It is essential that these special safety parts should be replaced with the same components as recommended in this manual to prevent Shock, Fire, or other Hazards. Do not modify the original design without permission of manufacturer.

General Guidance

An isolation Transformer should always be used during the servicing of a receiver whose chassis is not isolated from the AC power line. Use a transformer of adequate power rating as this protects the technician from accidents resulting in personal injury from electrical shocks. It will also protect the receiver and it's components from being damaged by accidental shorts of the circuitry that may be inadvertently introduced during the service operation. If any fuse (or Fusible Resistor) in this TV receiver is blown, replace it with the specified. When replacing a high wattage resistor (Oxide Metal Film Resistor, over 1W), keep the resistor 10mm away from PCB. Keep wires away from high voltage or high temperature parts.
Leakage Current Hot Check (See below Figure) Plug the AC cord directly into the AC outlet.
Do not use a line Isolation Transformer during this check. Connect 1.5K/10watt resistor in parallel with a 0.15uF capacitor between a known good earth ground (Water Pipe, Conduit, etc.) and the exposed metallic parts. Measure the AC voltage across the resistor using AC voltmeter with 1000 ohms/volt or more sensitivity. Reverse plug the AC cord into the AC outlet and repeat AC voltage measurements for each exposed metallic part. Any voltage measured must not exceed 0.75 volt RMS which is corresponds to 0.5mA. In case any measurement is out of the limits specified, there is possibility of shock hazard and the set must be checked and repaired before it is returned to the customer.
Leakage Current Hot Check circuit
Before returning the receiver to the customer,
always perform an AC leakage current check on the exposed metallic parts of the cabinet, such as antennas, terminals, etc., to be sure the set is safe to operate without damage of electrical shock.

unit under test. 2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface such as aluminum foil, to prevent electrostatic charge buildup or exposure of the assembly. 3. Use only a grounded-tip soldering iron to solder or unsolder ES devices. 4. Use only an anti-static type solder removal device. Some solder removal devices not classified as "anti-static" can generate electrical charges sufficient to damage ES devices. 5. Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage ES devices. 6. Do not remove a replacement ES device from its protective package until immediately before you are ready to install it. (Most replacement ES devices are packaged with leads electrically shorted together by conductive foam, aluminum foil or comparable conductive material). 7. Immediately before removing the protective material from the leads of a replacement ES device, touch the protective material to the chassis or circuit assembly into which the device will be installed. CAUTION: Be sure no power is applied to the chassis or circuit, and observe all other safety precautions. 8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise harmless motion such as the brushing together of your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity sufficient to damage an ES device.) General Soldering Guidelines 1. Use a grounded-tip, low-wattage soldering iron and appropriate tip size and shape that will maintain tip temperature within the range or 500 F to 600 F. 2. Use an appropriate gauge of RMA resin-core solder composed of 60 parts tin/40 parts lead. 3. Keep the soldering iron tip clean and well tinned. 4. Thoroughly clean the surfaces to be soldered. Use a mall wirebristle (0.5 inch, or 1.25cm) brush with a metal handle. Do not use freon-propelled spray-on cleaners. 5. Use the following unsoldering technique a. Allow the soldering iron tip to reach normal temperature. (500 F to 600 F) b. Heat the component lead until the solder melts. c. Quickly draw the melted solder with an anti-static, suctiontype solder removal device or with solder braid. CAUTION: Work quickly to avoid overheating the circuitboard printed foil. 6. Use the following soldering technique. a. Allow the soldering iron tip to reach a normal temperature (500 F to 600 F) b. First, hold the soldering iron tip and solder the strand against the component lead until the solder melts. c. Quickly move the soldering iron tip to the junction of the component lead and the printed circuit foil, and hold it there only until the solder flows onto and around both the component lead and the foil. CAUTION: Work quickly to avoid overheating the circuit board printed foil. d. Closely inspect the solder area and remove any excess or splashed solder with a small wire-bristle brush.

IC Remove/Replacement Some chassis circuit boards have slotted holes (oblong) through which the IC leads are inserted and then bent flat against the circuit foil. When holes are the slotted type, the following technique should be used to remove and replace the IC. When working with boards using the familiar round hole, use the standard technique as outlined in paragraphs 5 and 6 above. Removal 1. Desolder and straighten each IC lead in one operation by gently prying up on the lead with the soldering iron tip as the solder melts. 2. Draw away the melted solder with an anti-static suction-type solder removal device (or with solder braid) before removing the IC. Replacement 1. Carefully insert the replacement IC in the circuit board. 2. Carefully bend each IC lead against the circuit foil pad and solder it. 3. Clean the soldered areas with a small wire-bristle brush. (It is not necessary to reapply acrylic coating to the areas). "Small-Signal" Discrete Transistor Removal/Replacement 1. Remove the defective transistor by clipping its leads as close as possible to the component body. 2. Bend into a "U" shape the end of each of three leads remaining on the circuit board. 3. Bend into a "U" shape the replacement transistor leads. 4. Connect the replacement transistor leads to the corresponding leads extending from the circuit board and crimp the "U" with long nose pliers to insure metal to metal contact then solder each connection. Power Output, Transistor Device Removal/Replacement 1. Heat and remove all solder from around the transistor leads. 2. Remove the heat sink mounting screw (if so equipped). 3. Carefully remove the transistor from the heat sink of the circuit board. 4. Insert new transistor in the circuit board. 5. Solder each transistor lead, and clip off excess lead. 6. Replace heat sink. Diode Removal/Replacement 1. Remove defective diode by clipping its leads as close as possible to diode body. 2. Bend the two remaining leads perpendicular y to the circuit board. 3. Observing diode polarity, wrap each lead of the new diode around the corresponding lead on the circuit board. 4. Securely crimp each connection and solder it. 5. Inspect (on the circuit board copper side) the solder joints of the two "original" leads. If they are not shiny, reheat them and if necessary, apply additional solder. Fuse and Conventional Resistor Removal/Replacement 1. Clip each fuse or resistor lead at top of the circuit board hollow stake. 2. Securely crimp the leads of replacement component around notch at stake top. 3. Solder the connections. CAUTION: Maintain original spacing between the replaced component and adjacent components and the circuit board to prevent excessive component temperatures.

Circuit Board Foil Repair Excessive heat applied to the copper foil of any printed circuit board will weaken the adhesive that bonds the foil to the circuit board causing the foil to separate from or "lift-off" the board. The following guidelines and procedures should be followed whenever this condition is encountered. At IC Connections To repair a defective copper pattern at IC connections use the following procedure to install a jumper wire on the copper pattern side of the circuit board. (Use this technique only on IC connections). 1. Carefully remove the damaged copper pattern with a sharp knife. (Remove only as much copper as absolutely necessary). 2. carefully scratch away the solder resist and acrylic coating (if used) from the end of the remaining copper pattern. 3. Bend a small "U" in one end of a small gauge jumper wire and carefully crimp it around the IC pin. Solder the IC connection. 4. Route the jumper wire along the path of the out-away copper pattern and let it overlap the previously scraped end of the good copper pattern. Solder the overlapped area and clip off any excess jumper wire. At Other Connections Use the following technique to repair the defective copper pattern at connections other than IC Pins. This technique involves the installation of a jumper wire on the component side of the circuit board. 1. Remove the defective copper pattern with a sharp knife. Remove at least 1/4 inch of copper, to ensure that a hazardous condition will not exist if the jumper wire opens. 2. Trace along the copper pattern from both sides of the pattern break and locate the nearest component that is directly connected to the affected copper pattern. 3. Connect insulated 20-gauge jumper wire from the lead of the nearest component on one side of the pattern break to the lead of the nearest component on the other side. Carefully crimp and solder the connections. CAUTION: Be sure the insulated jumper wire is dressed so the it does not touch components or sharp edges.
NOTE : Specifications and others are subject to change without notice for improvement.
