I have a Sony Bravia LCD 46". The set is 1 year old. When I turn the set on in the morning the colors are blurry and run across the screen. This lasts no more than a minute , it just started doing this for almost 2 weeks now.

Could be 2 things:

1. Main board (BU board)

2. TCON board


Option 1: replacing the main board will run you a few hundred bucks for the Board and $300 in labor (or so) to get it installed.

Option 2: replacing the TCON means you might have to replace the whole screen (some TCONs are not available separately). A quick phone call or visit to Sony's part website will be able to determine which you need.

If you need to replace the screen, buy a new tv. The panels are amazingly, painfully expensive.

Now, there's a way to test which one is causing it, but you'll need to be quick.

For this experiment you will need: a screwdriver, a hair dryer, and some guts.

Take the back off the set, fire up your hair dryer and fire away at the TCON board (located at the top; it's a small board under a metal shield--you can't miss it).

Really warm up the metal shield and circuit board.

Now, plug in your tv and turn it on. If you don't see blurry colors and everything looks normal, you know it is the TCON board.

Can this be fixed ? what is the problem?


What your describing sounds very much like a video board issue some part is not working properly until it warms up. Eventually it will most likely need to be replaced, If you are not sure what board or part is bad, in the long run it might be a better idea to just replace the TV.

Hi,
A faulty Tcon board is often found responsible for wrong colour type faults. Some times the main board is also found faulty. If it has happened all of a sudden, it is not aging.

I have a problem with my Sony Bravia. The screen is cut in half with a fine black line. The top section is the picture that continuely rolls and bottom section is lines of colors. It is 9 months old.


Depending where you got it It's probably still under warranty.I know Bestbuy usually offers 1 year free.My tv had red lines running through it and they said it was something to do with a climate part that they did not have so I was sent to pick out a new Tv.Good luck
