Does not turn on the standby Shorted capacitor on the right side of the crystal just above the medi/tek processor Check if it is getting hot with your fingertip. Mariano
SONY KDL-32EX525
TV doesn't turn on, doesn't even show LED STBY 1) capacitor shorted on the tcom throwing the 12v to gnd, incredible because the tcom fuse didn't burn, it burned one of the power mosfets on the power supply board (q6410 - it's an 8118) leaving the tcon_vcc_12v connected directly. 2) after repairing the power supply board, the TV still wouldn't turn on. the 3.3v stby voltage was ok, but the stby led did not light up. I checked that the board has a 1.2v stby regulator that was without voltage, I removed the regulator and 4 capacitors from the line but none of them were shorted, I tried feeding the main board with 3.3v and 1.2v from a power supply. bench but the LED didn't light up. When I connected 1.2v from the power supply to the line, initially tsound was a short, I slowly released the current, increasing the voltage to check wsound the short was and suddenly the short disappeared. Apparently the short was inside the main IC of the board, when I released the current on the 1.2v line, what was shorted inside the IC burned and released the short. just changing the main board. 2000

SONY KDL-40BX455
Turns on, red LED lights up, then green LED and returns to standby, red LED flashing 6x. High voltage transformers changed on the driver board. one leaking loudly and the other open. Replace transformers t109, t110. Arock
SONY KDL46EX725
Does not turn on red LED blinks twice, sometimes turns on after several attempts. On the power supply board, locate 2 mega resistors, scrape the glue underneath all of them. Carlossbs
