Horizontal lines across tv

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.
Check the cables, connectors and connections.
Take it to a repair shop.

Sony Bravia XBR 40" LCD

1) Press MENU.
2) Scroll to SETTINGS.
3) Scroll to SCREEN.
4) Go to HORIZONTAL CENTER. Move the picture to the right. Hopefully, the line will go away. Otherwise, there is a problem with the pixels or the signal processor. Call 1-800-222-SONY. Or, Have a high-limit credit card handy for out of warranty repairs. Sorry about that.
