Now the TV can only be switched on with the remote control (or it goes to standby). the appliance goes to stand-by. No function, the power supply gurgles and whistles. Fault 1 The audio module has a short, therefore the power supply is intermittent. No function. Fault 1: Capacitor 2609 (8200pF/1500V) is defective. Fault 2: Power supply goes to protection mode. Check if power supply or loading is defective. Replace loading with a 220V (100W) lamp. If power supply ok then change C2609. Fault 3: Check if service no. starts with AG01. Appliance is set to protective mode. Check fuse T1638. Fault 4: Check if 300V present. If no 140V then check R3681 (6K8). Fault 5: + 140V is not present. Replace TS7687 (BUT12A; 4822 130 43919).

Fault 1: C2610 (180nf) has a short circuit, amplifier TDA1514. At start up the appliance goes into safety mode. Fault 1: D2609 has a short circuit (8.2nf) and D6609 is leaky. No sound. No picture. Blocked commands. May be intermittent. Fault 1: Check the power supply of the IC and F1642. The TV works intermittently. Fault 1: Resolder connector P05 on the display board/control board (module 1008). Poor locking in audio search. Fault 1: Remove module 1012. Change IC7038. Spontaneous operation (after a few weeks) in the wrong option mode (white picture, no teletext, no VHS). Fault 1: Replace zener diodes 6933 and 6934 on the SSP module. Appliance sometimes does not start, often only starts the second time around. Everything is fine from stand- by. Fault 1: Check resistors R3658 and 3659. After operating normally for a short time the TV goes from "Reception" to "Search". Fault 1: Check the IF module. Starts up after minimum 30 secs of the CRT lighting up. Fault 1: Check C2638 (10mf) that filters the 200V coming from t
