Flickering lines down the screen

I have a red flickering band about an inch and a half going down the screen. From the top of the screen to the bottom. What is wrong and what can be done to fix it? You can see through it but it is very annoying.

Panasonic TX-P42521B has a red/blue band across the screen (about2" wide) which is flickering and about 2" below is a broken red line. Any ideas? Thanks.

These symptom seems to be caused by a

defective D or SC board but in reality, they are

caused by a defective SD board.

To confirm this, disconnect the SD board from

the SC board (Follow proper SU/SD board
If the SD is defective, the screen will have a good picture at the top half of the screen and a completely black area in the lower half of the screen.

Whire vertical band , 3 inches wide with red kine in the middle

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.

most likely a loose connection if it is flickering.. if there are red squiggly lines usually means driver issue.. and if there are blue banding lines, typically means the chip is overheating/desoldering.

TV Flickers up and down and screen is shifted to the right w/ red color dominating the screen.

The most likely problem is the auto focus module.
A costly repair.
If you are going to fix it ask for a rebuilt one.
