Sony BRAVIA KLV-40U100M Issue

Correct. You have to connect the antenna to another box and then take the output of that box to the TV. An old VCR is ideal as this box.

dear User,

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

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.

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.

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

by going to people that are true helpers and not looking for the almighty dollar...............

tv smoked and will not power on

If this were just about any other brand, you'd likely be able to find another brand of TV with the same size screen and swap the inverter boards and the LVDS board. The problem with Sony is that the company uses internal designations. If you have homeowner's or renter's insurance, it might cover some of the cost. Otherwise, put the damaged set on eBay (you'll get a couple hundred dollars plus shipping) and go buy a new set. Likely, any larger set for sale with a good screen is going to go for more on eBay and finding one is rare.

The U series has two boards and it could be either the system/video board or the power supply board. It will take a tech to tell you which is bad

The resolution on this was to check the surge protector the television was plugged into. Once we unplugged and plugged into another surge protector, the screen went back to normal and the appearance was great. We believe this was due to one of the resistors within the surge protector may have become faulty.
