SERVICE PROCEDURES

1. Replacing the fuses

This symbol located near the fuses indicates that the

fuse used is fast operating type. For continued protection against fire hazard, replace with same type fuse. For fuse rating refer to the marking adjacent to the symbol.

Ce symbole indique que le fusible utlise est a rapide.

Pour une protection permanente, n'untiliser que fusibles de meme type. Ce darnier est la qu le present symbol est appse.

To perform a result, please follow the procedure below.

DESCRIPTION

TX-SR55

1.Press and hold down the VIDEO-1 button, then press the STANDBY/ON button.

2.After "CLEAR" is displayed, the preset memory and each mode stored in the memory, such as surround, are initialized and will return to the factory setting.

3. Unplug the power supply cord.

3. Safety-check out

(U.S.A. model only) After correcting the original service problem, perform the following safety check before releasing the set to the customer.

Leakage Current Check

Measure leakage current to a known earth ground(water pipe, conduit, etc.) by connecting a leakage current tester between the earth ground and exposed metal parts of the appliance (input/output terminals, screwheads,metal overlays, etc.). Plug the power supply cord directly into a 120V AC 60 Hz outlet and turn Standby switch on. Any current meausred must not exceed 0.5mA.
