SONY SXRD Powers off and on

bad power supply. Contact SONY for advice. They will pay for the repair and service call if it is still under warranty

Ok I know there was a recall on some Sony tv's regarding the optic block.. they were temporarily fixing them and it would not be a permanent fix so I ended up with a new tv, I would ck and see if your model was one of them. Good luck..

Strange situation, have you tried unplugging it for a few minutes and letting the TV cool. I have a older 2006 Sony SXRD rear projection and it takes forever to turn back on if you shut it off then turn it back on. Check this link and maybe its giving you a blinking code. Try counting the number of blinks. Hope this helps.

The yellowing of Sony’s KDF-60WF655 rear projection is a problem with the SXRD optical engine. This turned out to be a big problem on many of the SXRD TV's. Sony actually had a class action lawsuit that covered the optical engine for 5 years. My unit was replaced in June of last year (2009) about 1 month before the coverage ended. My unit had a bad yellow streak on the right hand side. Sony no longer covers the cost of replacement, as the class action suit has now expired. Sorry for the bad news. Its not clear if a new optical engine will suffer the same fate after a few years. Sony’s rear projection TV's are amazing and the picture rivals many of today’s LCD's and Plasma's. Any authorized Sony Tv repair shop will no exactly your problem and will be able to give you a fixed price to repair.
Hope this helps

Sounds like the line output transformer (flyback transformer) has gone out.Depending on how old the TV is will depend on if it is worth fixing

I believe 4 blinks is fan error. You can take back off and watch fans in particular the fan for the lamp (this one goes out the most) The TV has a sensor so it knows if the fan turns.You can take a pencil and use it to spin fan sometimes that will jump start it (not a permanent fix just a test). You can try cleaning dust off fan and replugging the connector on the wires coming from fan.Might fix it if not fan will need replacement.

The lamp may be starting to go, the symptoms you describe are classic warning signs. You could unplug tv let it cool down and check lamp most likely the glass will not look clear maybe a little milky or smoky in areas..dead give away.

how many times does it blink pause then blink again?
