The image disappears on my tv screen. A horizontal line appears.

After being on for a while, the image on the screen suddenly disappears and a horizontal line appears. I have to tap the tv in order that the image reappears. Sometimes, I do this several times.

You need to check the horizontal IC for deffects, possibly and most likely there are dry joints on the legs of the Horizontal IC. Have all the legs on the IC soldered nicely, this shud sort out your problems as you say you hit the TV then works. Try this before replacing the IC

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.

Tap the top of the TV and if the picture comes on in full screen then it is possible that there are DRY SOLDERING points on the board.
use a good iron to touch up the soldering on the vertical and horizontal sections, the driver IC's. get help if you are not able to do the job but it seems a minor job.

you must open the back cover of tv, and then things you should do is set "SCREEN" adjustment on the flyback transformer. you must turn it counterclockwise to reduce and decrease the level of screen brightness. turn screen adjustment gradually until the horizontal blanking lines disappear from the screen. and blurred images will be sharp again

Mitsubishi #VS-45605


We had a blue cone on the screen. We have adjusted the sharpness, contrast, and cross hairs. The cone has almost completely disappeared, but we still have blue shadows. Could this mean a blown color tube?

Any suggestions would be greatly appreciated.
