If the lines go all across the screen and they are like one or two pixel wide,
that is a symptom of a bad lcd panel

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.

Can you please change the input device to some other you know, works? If you do not notice any problem there, look for the aerial cable going close to any power line or has interference from some other transmissions of any kind nearby.

Lines down screen


We have a Samsung LE32A457, whilst we were watching T.V tonight the top halve of the screen suddenly appeared with green lines halfway down the screen and that half of the picture was unwatchable, T.V is 2 years old. We have removed all scart leads but this did not help and the problem still exists, when shutting down a white horizontal line across the centre of the screen appears from this line upwards the picture is faulty. Any help or advice would be grateful.

White flickering line across top of screen


Set the screen format using your TV's menu. Do not set the format of the screen using your provider's receiver. I had this prob with a few channels with a dish provider when I set the format with the remote from the dish provider. I picked up the TV's remote, went into the menu, set the format, problem fixed.
