My sony bravia BX42 has a color green horizontal line and it makes bigger and bigger until some color pink was appeared then I am worried if it will not turn to normal as it goes :(
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 hope this helps it seems Sony has extended warranty coverage for your TV for this issue.

Yeah we have the same exact problem here. Defective TV....ours would correct itself after 30 mins, but now it's blurry all the time. I'm never dropping 2K on a SONY tv again.
