My Sony KDL 46W4100 LCD TV now displays numerous thin, yellow horizontal lines which are becoming more numerous. What is this and how can it be fixed?

SOURCE: Similar question as everyone else. I bought a

I just read some Sony literature about T-Con issues and how to determine if the problem is the T-Con or the LCD panel. One of the examples they gave was exactly as you are describing. Unfortunately according to Sony the panel has failed and the only way to fix the problem would be replacement which is very cost prohibitive. Your other option would be to contact Sony and make them aware of your situation. Try speaking with as many people as possible and write down names. I have heard of times that they replaced the TV for free but to be honest I don't know of anyone who has been that lucky. Their number is 1-239-768-7547 Monday through Friday 9:00am to 8:00pm ET.

I have a Sony Bravia KDL-46w4100. It has started to dark screen on start up. It sounds like this is a common problem for Sony tvs. Does anyone know the fix?


If you are not afraid of taking the tv apart you can check the connections of the ribbon cables and check to see if you have any swollen capacitors. If these look good your control board may be going out.

This is on protection mode and an error indication. Switch off TV, remove plug after switching off power outlet, wait for 48 hours and retry. If problem persists, it might need attention by a qualified service technician.

HI,
Your tv have problem with the T con board. The t con board drives the Pixels in the lcd screen . If there is some problem with the t con board then this can exibits such problem as you mentioned. Normally you can find the t con board in the bottom center of the lcd coverd with a metal cover. Its part number is SONY T-CON: E40951307. If its avilable then try to replace the same which will solve the problem. Its a regular complaint with the Lcd tv's. I have added the picture of tcon board.

Som times if there is any loose conatct in the pannel connection which comes to the t con board then also the same problem can occur. Before going to replace the board do one thing remove all the connections to the t con board and reconnect it. Some times it will solve the problem. If you need any more assistace feel free to conatct me through fixya.
