Does not turn on, stand by LED is off | TV doesn't turn on or standby, 3.5 v power supply is only 1.5v...disconnect from the main cable, power supply went up to 3.5v, I went to the main to look for a short, I found some 4.7 caps with high ESR, I changed them and nothing, I injected 3.5 v x 500ma and I didn't notice high consumption, the main LEDs lit up, I concluded that the main one wasn't defective, I went back to the power supply and found c510 and c506 (47u x 25v) with high ESR and completely dry, they measured zero with an analog multimeter, I just had to change it (mine conclusion and that the power supply did not supply the main consumption) | Replace | Maurilio |
