Having problems with your Flat Panel Televisions ?

Sony KDL-40U2000 will not turn on. No lights at all, totally dead.

\015 I have dones some testing the AC input voltage is present and internal fuse is intact. I have tested for the 5v DC stby voltage (on connector CN6003) and it isnt there. All of the capacitors have been visually checked and there are none that are leaking or buldging. Ive also checked the upper plug connectors for DC voltage (CN6004 and CN6005) There is also no voltage present there.\015

Answers :

I think the 5 volts missing is your problem---it should come from the standby power supply and ought to be there all the time.

Look to the source for that voltage and check to see if a dead short to ground on that line.

I have a Sony Bravia KDL-40S4100. I turn it on and I can hear the solenoid click, the green light is on and I get a faint blue illumination. I do not get a picture or sound... or any response from the remote except for on/off. I tried unplugging it until I heard a click (I assume all the caps were discharged at this time) and tried again, still nothing but a green light and faint illumination. Any idea what I am dealing with... besides frustration?
