    I have a similar issue with my Hitachi 50in. Rear Projection TV. The screen is scrambled and jumps around like a bad connection. If the tv is left on long enough the problem goes away for the most part.

Have thin line of picture on right side of screen, rest is blank. Sound is fine


Hi,

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.

I got multiple thin colors on the middle of the screen


My 3-year old 52-inch Toshiba flat panel TV (Model # 52RV53U, Serial # AM409000295) developed a display issue (purchased Aug. 2008, manufactured July 2008). Vertical multicolored lines appeared on the screen just left of center. The band of thin vertical bars is 5.5 inches wide. The lines are about 1/16-inch wide. They are stationary, always exactly in same place. They over-ride any other picture on the screen (no transparency). They are there all time even with no video inputs to the TV after the unit is turned on. See picture #1. The TV works well in every other respect, but, obviously, it is annoying to watch the picture with the color band blocking about 1/6 of the picture.

I already swapped out the TCON board with no improvement and replugged the TCON board cables with no improvement.

Most likely it is the flat panel tab bond failure (panel made by Samsung). Further updates will be on my Facebook page.

Screen is black except for thin line in middle of screen


The problem is in the vertical section of the main board. Bad capacitors and maybe the vertical IC. If you are not inclined to be a tech you will have to take it to a shop.. I don't know what they may charge but I normally get $69- $89

No Picture


This is a problem with the vertical circuit. If you can solder, you should be able to fix this. With teh unit unplugged, open up the back and locate the vetical IC. This should be a small flat IC attached to a heatsink with about 9-11 pins. It may be marked LA7837 or something similar. Try resoldering hte pins. If that fails to resolve the problem, replace the IC. I will look up your specific model and try to get more details.

Tv not working


this symptom, sometimes called the tube light effect, it is characterised by a bright thin horizontal line across the middle of the screen. this symptom is caused by a breakdown in the vertical deflection circuit. hence maybe the trouble maybe in the vertical oscillator, amplifier or output circuits. but if all i have said is not clear to you, better bring it to a qualified tv technician. good luck!
