You have found the problem.
If this set is under warranty you should return it to get it repaired/replaced by the seller. If not then;
This sounds like the power supply board has failed. The electrolytic capacitors on the board need to be replaced.

IF YOU KNOW HOW TO WORK WITH ELECTRONICS REPAIR(soldering ) or have a friend with knowledge/skill you can fix it. If you can not solder then you can replace the board.

>Unplug the set and any cables.
>Remove the back cover.

>look at the capacitors on the power supply board. If the top of any of them are bulging up then that is the problem.

>You will have to replace ALL the electrolytic capacitors except for perhaps the large one.
>Disconnect and remove the power supply board. Handle by the edges to prevent contaminates and static electricity.
> Use ones with the Low Equivalent Series Resistance ESR rating
> Use ones with the same farad rating

> Use ones with the same or higher voltage rating
> Use ones with high temperature rating
> Install one at a time to prevent mix-up and keep the polarity correct.

> Leave a space between the PC board and the bottom of the capacitors for expansion. They heat up.
> Replace power supply board and reconnect cables..
> Replace back cover.


Sources for some good capacitors are or NTE. Try for a local outlet of NTE products.
You can also search for other sources. Some companies even sell all the capacitors in a kit.

Total price of parts should be < $30.00

Yes you can buy a new power board but if the capacitors have not been replaced they will eventually fail also.

Lamp light blinking red

From your description it sounds like the lamp bulbs needs to be replaced.
You need one of these:
NOTE: DO NOT TOUCH THE GLASS PART OF THIS BULB. The smudges from your fingers can show up on the image projected onto your screen and make things look blurry.
Once you have the new bulb then turn off the TV and unplug it. On the back panel there is a rectangle on the left with a screw holding it on. Use a philips head screwdriver to loosen the screw then slide the rectangular panel to the left and pull it off. Inside will be the old lamp bulb. Use the screw driver again to remove the screw holding the lamp bulb in and pull the lamp bulb out (it may be hot). Insert the new bulb and then screw it back in. Place the panel back on and screw it back in as well. Make sure the screws are tight or the TV may not turn on. You can now plug the TV back in and turn it on. If done correctly this should resolve the issue.

Try using a different Tv.

"First beep it turns on second beep nothing and third beep turns off.will not reset."

Your friends are wrong, pressing the button at the front of the console only turns the console on and off. If the problem doesnt change then contact the sony customer helpline.
