If you can do it, then just reheat or resolder the vertical ic pin for first step. If this work then no need to change the IC. Good soldering technique is needed. Do this when unit is no power and unplugged from wall socket.

Remember nasty voltages inside, it might caught you.

Replace the vertical IC you will need to discharge the flyback and replace the IC it can be done if you know what your doing but there are a lot of youtube videos to show you how this is to be done.

If this is a tube type or crt type. Your vertical circuit has a problem. Could be the vertical IC loose connection on its board. Or the vertical ic itself is faulty. If just resoldering or refluxing of its pins doesn't help check some minor cmponent within vertical circuit. Or the vertical ic is defective already.

If your not inclined on electronics never do the repair itself, nasty voltages might caught you.

Single green line spanning across the screen horizontally


I was just watching TV and all of a sudden the screen minimized down to a single green line spanning across the screen horizontally. The label in the back says it was made in 1996 so it is an old tv. Can anyone help?

TV: bright line across black screen for several hours.


vertical output ic needs to be resoldered. careful leaving that bright line displayed on the screen as this will cause a permanent phosphor burn into the tube. this can not be corrected once burned unless you replace the tube. mch

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.

White Horizontal line across screen


It is most likely the vertical deflection IC has overheated and lost its soldering. If you open your TV up, it is a 10-15 pin in a row IC sticking out of the motherboard attached to a heatsink. It should be labeled "IC451." Give it a wiggle, see if it affects the picture, You may have to resolder them in place.

The IC may be hard to find, look for a peice of metal that is sticking out of the motherboard, attached to a small chip. I fixed a samsung tv that had it in the middle area.

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!
