Hi Nick, Please trace the 12V line. Most probably it is coming from the main board.

I have a Sony Bravia 32" and half the picture is


This is likely a problem with your TCON circuit board inside the back of the tv.

The TCon board usually has 2 very thin ribbon like cables running from connectors on the board to the actual LCD screen panel. Each ribbon controls one half of the screen. If you are lucky, it's possible one of the ribbons came loose or is not making proper electrical contact with the connector on the TCON board.

If your tv is out of warranty and you are comfortable working safely with electronics then you may be able to repair this yourself with a few hours of screwdriver work. The ribbons may just need to be reseated in the little flip up connectors, or you may have to clean the copper at the tips of the ribbons gently with a pencil eraser to remove any oxidation.

If you are unlucky enough to have a bad TCON board or are not comfortable disassembling your tv yourself then you can bring it in to the shop and they can probably repair it for less than $150.

Good luck.

My sony bravia kdl46vl130 goes into standby flashes red 5 times no picture no sound


Information from Sony:
TCON Error 5X
Communications have been lost between the video processor on the FB3 board and the TCON (TFT Control) board which is part of the LCD panel. This can be caused by a defective FB3 board, a defective LVDS cable, or a TCON failure.

Sony bravia LCD KDL52 TV: blurred picture with color bands


It is most likely the TCON board (located at the top right against the LCD panel). When these boards have problems, they can act up when cold or warmed up.

You will want to check with any extended warranty company you might have, or Sony's part website for the availability of the TCON board.

The problem here is, sometimes those TCONs are not made available separately and need to be replaced with the screen.

If you have to replace the panel, buy a new tv. You'll save yourself a costly repair.
