If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Take it to a repair shop.

This type of sound can be generated by the back-light inverter board.

Sounds like a bad LCD panel, these would give like horizontal lines and double images below.. Sony said it was the TCON board, but that is part of the panel. Call sony cust. service and complain about the issue, they were extending the warranty for such failures as the got a bad batch of LCD panels.. if sony doesn't help it will cost over $1000 so get them to help and they should, they're a good company.


they will want model #, serial #, and date of purchase before helping you.... make a good guess on the DOP if you don't know it, other #s on back of tv

Next is call sony for information---you want to know if this is a known issue in this model TV.

Sony BRAVIA... | Answered on May 26, 2012

Three suggestions:

1. Try to hook cable direct without box to see if same problem---ie the box might cause this problem.

2. Check to see if it does it with DVD or when you change active inputs.
3. If number one contact cable provider as box may be your problem.

Hi check to make sure the antenna is connected correctly. try tunning the channels manually and if they come up you can save them one at a time. Also try moving the antenna to a different location. make sure the TV is set to scan on the same input that you are connecting the antenna. If all that fails ou might have a defective tuner board.

YHi this can be cause by two things. Either your screen is defective or your t-con board is defective. The t-con board would be the more economical to replace.

You are correct, it can be the T-CON or the LCD panel itself, there is no 100% solution to this, but swapping the T-CON first, may be try reseating the ribbon cables between the LCD panel and the T-CON first (not easy to get to and must be real carefull!).

A line on an LCD screen can be cause by the screen itself going bad or the T-con board. The T-con board the attached to the screen on the backside and covered by a heatshield. If you get teh part number from it you can find it online from one of the many retails that might have it. Like www.interliquidparts.com

check the ground connection of your house wiring. fist of all remove all the external input like set top box, cable connection, dvd etc from the tv. Then power on the tv and watch is the wave is there or not. if it there then ,if the tv power cord comes with three pin connector then remove the earth connection on the wall outlet socket to which you connect its power. the connect the power and switch one the tv.
if the wave will not appear then connect external devices (set top box, dvd etc) one by one and watch which device produce this wave in the tv. also check the ground connection of that device which produce this wave.
If all these will not help full then the SMPS power supply of your tv have some problem. Normally this type of complaint arises due to the faulty Main filter capacitor. you can see it in the power supply.. It will be the big capacitor according to others. Normally There will two or more. replace the same. will solve this problem. if you need any more assistance feel free to contact me through fixya
