My sony bravia model KDL-46EX500 is three years old. It has worked fine until this morning when I tried to turn it on. The cable box and everything else comes on. I unplugged it for an hour, but it still did not come on. No green or red lights come on. I tried it with the tv's remote and the one I use from the cable company. I also tried to power it on from the tv itself. Help! I paid a lot of money for it and cannot afford to bring it somewhere.

I had the same problem. The sound and picture went off for about one minute and the green power light flashed green. Then the TV came back on. It sometimes stayed on for hours and sometimes went off again in a few minutes. The TV is just over 3 years old. Had the service people out and the problem was the bulb. It cost $420.00 to fix. He said our bulb lasted twice the average life. I wish that I had known this since it is a simple fix and the cost of the bulb on line is under $200.00.

The solution to this problem was the Relay RY6001 replacement. I was able to find a suitable part from CPC check out:-
http://cpc.farnell.com/schrack-components/rtb74005/relay-pcb-spco-5vdc/dp/SW02588
for the details. The part fitted Ok when one of the pins is cut off. You do not need this pin so it is OK.

I have a full set of fix it photos if anyone needs them. It took about 40 mins to strip, replace and re-biuld the TV - there are loads of screws to get at the PCB and then you have to put them all back!!

Thanks again to mgnut for all the info.

Hi it sounds like it could be an issue with board that powers the lamp ,it's called the ballast.When you put a new lamp in the ballast has to provide more power ,when it starts to go weak it will not light up.Sometimes you can put your old lamp in and will work fine.Try partstore.com they might have it right there.Hvae a blessed one!

According to other posts I have read (I have same problem) there is no power getting to the fans. They recommend re-seating the fan harness again as it might have come loose or might have dust etc., in it.

I have no idea how to do this yet but that is what the trouble-shooting guide says.
