SOURCE: The TV has horizontal lines across about 5 inches

Horizontal lines are relatively rare problem in LCD TVs.

The likely problematic areas are:

1) The LCD itself (the micro ICs embedded into the LCD panel structure); that doesn't sound likely based on what you say, but it's not completely impossible. The bad news is it's mostly uncurable.

2) The power board A-1511-322-D G5
Power boards may sometimes cause problems with display, although rarely causing horizontal lines.
I wouldn't start looking here either, but it is certainly a problem to consider.

3) Main board 1-876-561-13 R1506072C
Slightly more possible and yet not quite likely. A high operating temperature and bad SMD soldering process may cause some soldering contacts on the main board to behave differently when the board is cold versus when it heats up. It is very common and may have all kinds of different effects on the TV and the screen.
One way to check for that is with a regular dryer..the process is explained in many other solutions at fixya and around the net, so I wouldn't repeat it here...but it takes time and patience.

4) The most likely place to start with is the T-Con / LCD controller
404652ASNC6LV4.1 M139.

I'd first replace that and see if the problem goes away.

5) There's a very minor chance that the LVDS cable that connects the main board with the T-Con does not make good contact initially and changes that as a result of getting hot. It's easy to just touch and move it lightly when the TV is still cold to see if it has an effect on the picture.

Sorry I couldn't just nail it for you, but that's the nature of the repair businss :-)

Fixed non moving lines usually means you have a problem in the panel display or t-con. If it is in warranty get it to a factory authorized service center. If not you can try to change the t-con and see if this fixes the problem, if not then it will be the panel it's self and will be cost prohibitive to repair.

I have a Bravia KDL-52w4500. Over the last month I have started to get more and more horizontal line across the screen. These do not go away. What can I do to fix this


unfortunatly, horizontal lines on an lcd tv, almost always mean a bad lcd panel. if it is out of warranty, it will be really cost prohibitive to replace the panel. if the set is only a year old or so call sony customer support and ask for a concession for the part.

This sounds like what I managed to do to my screen, even though I knew better. Is there any chance you layed the screen face down at some time?

Even though you can still watch it OK, you probably have hairline fractures in the screen face (NOT the screen itself- be thankful for that- the cracks are in the screen coating). LCD screens are a very thin glass laminate with a thin protective glass-like coating. When they are laid flat (like I did to connect cables) if the screen bears any weight, microcracks develop on the front of the screen.

I am sorry to say that the effect is permanent.

Hi,
I'm sorry, it sounds problem with lcd panel (screen) that is defective and causing lower half distorted image. If tv is under warranty then call number written on warranty documents for warranty cover or lcd panel (screen) replacement would cost you approx 80% of new tv price.
Hope these info will help you.

Line thru screen


The LCD Panel must be replaced to fix both problems. The cost in doing this would exceed the value of the set. I recommend not putting the money into it.
