Important Safety Notice

1. Safety precautions
This monitor is manufactured and tested on a ground principle that a users safety comes first. However, improper used or installation may cause damage to the monitor as well as to the user. Warning: This monitor should be operated only at the correct power sources indicated on the label on the rear of the monitor. If youre unsure of the power supply in you residence, consult your local dealer or Power Company. Do not try to repair the monitor by yourself, as it contains no user-serviceable parts. This monitor should only be repaired by a qualified technician. Do not remove the monitor cabinet. There are high-voltage parts inside that may cause electric shock to human bodies. Stop using the monitor if the cabinet is damaged. Have it checked by a service technician. Put your monitor only in a lean, cool, dry environment. If it gets wet, unplug the power cable immediately and consult your closed dealer. Always unplug the monitor before cleaning it. Clean the cabinet with a clean, dry cloth. Apply non-ammonia based cleaner onto the cloth, not directly onto the class screen. Do not place heavy objects on the monitor or power cord.

Product safety notice

Many electrical and mechanical parts in this chassis have special safety visual inspections and the protection afforded by them cannot necessarily be obtained by using replacement components rated for higher voltage, wattage, etc. Before replacing any of these components read the parts list in this manual carefully. The use of substitute replacement parts, which do not have the same safety characteristics as specified in the parts list, may create shock, fire, or other hazards.

Service notes

When replacing parts or circuit boards, clamp the lead wires around terminals before soldering. Keep wires away from high voltage, high temperature components and sharp edges. Keep wires in their original position so as to reduce interference. Adjustment of this product please refers to the user manual.

Note 1

Note 2
Note1: Pass: Normal display image with no obvious non-uniformity and no line defect. Partial
transformation of the module parts should be ignored. Fail: No display image, obvious non-uniformity, or line defects.
Note2: Evaluation should be tested after storage at room temperature for one hour. Note 3: The MTBF (exclude the CCFL ) calculation is based on the assumption that the failure rate
distribution meets the Exponential Model.

E. Safety

1. Sharp Edge Requirements
There will be no sharp edges or corners on the display assembly that could cause injury.

2. Materials a. Toxicity

There will be no carcinogenic materials used anywhere in the display module. If toxic materials are used, they will be reviewed and approved by the responsible InnoLux Toxicologist.

b. Flammability

All components including electrical components that do not meet the flammability grade UL94-V1 in the module will complete the flammability rating exception approval process. The printed circuit board will be made from material rated 94-V1 or better. The actual UL flammability rating will be printed on the printed circuit board.

c. Capacitors

If any polarized capacitors are used in the display assembly, provisions will be made to keep them from being inserted backwards.

F. Display quality

The display quality of the color TFT-LCD module should be in compliance with the Innoluxs Incoming inspection standard.

G. Handling precaution

The Handling of the TFT-LCD should be in compliance with the Innoluxs handling principle standard.

1. No Power & LED Off

Unstable power

Check sampling Circuit

Check R822, R823, R824

Change R822,R823, R824 Check the R pin voltage of IC803 about 2.5V Check the C pin voltage of IC803 if 3V

Change IC803

Check R819, R820
Check pin2 of IC802 voltage is 3V
Check R818, D804, C807 if short

Change R818, D804,

Check pin1 of IC802 voltage below 1V
Change R808, R 809, R810, R 811, R815,
