Question about Sony BRAVIA KDL-32S2000 32 in. LCD HDTV
I own a Sony KDL-52XBR4 HDTV, anyways when I power the TV on on the lower part of screen I would say 2 to 3 inches high is blurred and distorted,all the way across and stays like that for a duration of time which varies. What are my options?
It sounds that the CCFL lamp at the lower part is faulty. The fault is with its back-light itself. Check it. If you wish to get more details about these type of faults to LCD TVs, check the site linked here. It has stap-shot illustrations to these type of fault to LCD TVs; which I cannot include here by this window. http://electronicshelponline.blogspot.com/ Pull up previous posts there, either by type in the Brand name to your set in its search box, or view it in Mosaic / Timeslide / Flipcard option.

Also I have a Sony Bravia and it clicks while it is on as well. I read that forum and some people said to disconnect the cable box for 10 sec. and then some said it was the heat from the summer.. i don't know.. I just turned my tv off and then back on and it stoped. I read this is happening with all kinds of TVs....

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
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 :-)
