dear User,

supply board isshue.kindly take off your rom lite then check if dim picture is coming then its supply issue

Check the U24 (CPU reset IC) on the "A" board. It may be burned. If you have a DVM (voltmeter) check for 3.3V across SW1 connections near this device. If you don't have 3.3V, U24 is bad. This part is not available from Sony. The TV may work if you just remove U24 from the board. I posted this fix on Agoraquest also, you can read more there (I'm "Roundabout" on that forum). Hope that helps

Using the Sony remote, press the "Wide" button, repeat until TV displays "Full". Hope this helps

It appears your looking for a power supply. Only place I could locate one was on ebay here http://cgi.ebay.com/1-789-496-11-New-Sony-Power-Supply-Board-KLV-40U100-/270664532068?pt=LH_DefaultDomain_0&hash=item3f04dd0064

You can also check shopjimmy.com but they were showing out of stock.

Good luck!

I would take back because this is a Power supply problem.

use set up box,eg tata sky or airtel

First remove the back panel from the set. Next look at the bottom and you'll see an aluminum bracket that connects the base to the frame of the set. Remove the four screws, replace the back and you're done.

Power supply module will be he first place to check.

Look at the power supply first; look for burnt parts, bad capacitors, etc. Look for 5vdc, 12vdc, and 24dvc.

try resolder only,,,

Hi,
Service manual does not have specific part number for inverter boards as these are considered part of lcd panel. Sony Parts will provide you lcd panel including inverter boards and t-con board already fixed on lcd panel.
However, you need to replace both boards (master and slave) to solve the back light issue.
Hope this info will help you.
Thanks.

No,this tv a LCD not a DLP.The LCD inverter board is dead.Must replaced to get picture back.The board is usally a long board.Tries Shopjimmy.com,Ebay.com to buy the board.
