White line across screen


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.

Our LN40A630 has three horizontal white lines across the screen on power up (center, center of upper half , and center of lower half). After about five minutes the lines go away. Tried Picture Test in...


This is a sign of your LCD panel beginning to die. Sometime soon those lines won't fade away and will become permanent parts of your TV screen.

Considering the fact that your TV is approx 3-4 years old, this is normally the expected lifespan of a TV. Once the TV becomes unwatchable, your best bet would be to begin shopping for a new one.

That sounds correct, I just have to work on SONY BRAVIA KDL-40BR4 with Horizontal lines problem on ther right side, you you tap around the frame, the lines will come and go, this is only 2 years old TV! Poor quality panel made by SONY/SAMSUNG company jointed venture.
Very sad indeed when you paid for BRAVIA series which are not cheap.
New screen will cost more than new TV.

The top half of my Sony Bravia 32" screen plays as


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.
Thanks.

Permanent Vertical Line on my Sony Bravia 46 inch LCD TV


What you're describing is usually the result of an improperly seated connector. With the power disconnected, open the tv and locate any connectors between the LCD screen and the driver circuit board. Unplug them, and reconnect it assuring it's properly and firmly seated. Be careful when handling these cables as they tend to be quite fragile... take your time.
