SECTION 3 DISASSEMBLY
3.1 DISASSEMBLY PROCEDURE 3.1.1 REMOVING THE REAR COVER Unplug the power cord. (1) Remove the 16 screws [A] as shown in Fig.1. (2) Withdraw the REAR COVER toward you. CAUTION: When reinstalling the rear cover, carefully push it inward after inserting the MAIN PWB into the REAR COVER groove. 3.1.2 REMOVING THE CHASSIS (CHASSIS BASE AND CONTROL BASE) Remove the REAR COVER. (1) Slightly raise the both sides of the CHASSIS by hand and remove the 2 claws [B] under the CHASSIS from the front cabinet as shown in Fig.1. (2) Withdraw the CHASSIS backward. (If necessary, take off the wire clamp, connector's etc.) NOTE: When conducting a check with power supplied, be sure to confirm that the CRT earth wire is connected to the CRT SOCKET PWB and the MAIN PWB. 3.1.3 REMOVING THE AV TERMINAL BOARD Remove the REAR COVER. (1) Remove the 4 screws [C] as shown in Fig.1. (2) When you pull out the AV TERMINAL BOARD in the direction of arrow [D] as shown in Fig.1, it can be removed. 3.1.4 REMOVING THE CONTROL BASE Remove the REAR COVER. Remove the CHASSIS. (1) While pushing down the 2 claws [E] as shown in Fig. 2 and pull out the CONTROL BASE in the direction of arrow [F] as shown in Fig. 2, the control base can be removed. (If necessary, take off the wire, connector's etc.) 3.1.5 REMOVING THE SPEAKER Remove the REAR COVER. (1) Remove the 2 screws [G] as shown in Fig.1. (2) Withdraw the SPEAKER backward. (3) Follow the same steps when removing the other hand SPEAKER. 3.1.6 CHECKING THE MAIN PW BOARD To check the back side of the MAIN PWB. (1) Pull out the CHASSIS. (Refer to REMOVING THE CHASSIS). (2) Erect the CHASSIS vertically so that you can easily check the back side of the MAIN PWB. CAUTIONS: When erecting the chassis, be careful so that there will be no contacting with other PW Board. Before turning on power, make sure that the CRT earth wire and other connectors are properly connected. When repairing, connect the DEG. COIL to the DEG. connector on the MAIN PWB. 3.1.7 WIRE CLAMPING AND CABLE TYING (1) Be sure to clamp the wire. (2) Never remove the cable tie used for tying the wires together. Should it be inadvertently removed, be sure to tie the wires with a new cable tie.

5.1 SELF CHECK FUNCTIONS 5.1.1 OUTLINE This model has self check functions given below.When an abnormality has been detected, the SUB POWER is turned off and POWER LED flash to inform of the failure. An abnormality is detected by the signal input state of the control line connected to the microcomputer.
5.1.2 SELF CHECK ITEMS Check item B1 over-current protection Details of detection An over-current on the low B1 line is detected. Method of detection The main microcomputer detects the possible abnormality at 30-msec. intervals and judges the results in every 16 time. Of the 16 times, if NG is detected more than 9 times, it is judged that there is an abnormality. DITTO State of abnormality When an abnormality has been detected, the SUB-POWER is turned off. While the SUBPOWER is being turned off, the POWER key on the remote control unit is not operational until the power cord is taken out and put in again. DITTO
