Most Probably the Vertical Output IC has failed. If it has, it also could cause resistors that supplt the +/- Voltages to the IC to fail as well.
Hope this helps,

TV has a great picture but wont "hold it". Keeps going to a single flat horizontal line across the middle of the screen. Tapping on side of TV used to bring it back but now, nothing. Just a line.


Vertical scan output section circuit fault. Absence of vertical scan causes the single horizontal line on screen. Horizontal scan output section is OK. Contact any service technician to troubleshoot the vertical scan output section circuit. If you wish to get some details; check the site linked here. Pull up older posts.Surf the site with patience.http://electronicshelponline.blogspot.com/

Picture goes to a single horizontal line.


Your problem is due to failure of the vertical scanning circuits in your TV. This is quite common and is caused by aging components. Generally drying out capacitors
You got to be careful not to leave it on too long when the picture collapses, it will burn a permanent line across the screen.
If you are an electronics expert you can fix it if you get a schematic. If not please don't attempt to reapir it yourself since there is high voltage in side the TV.
The problem may get worse with time.

My CRT TV displays a single horizontal white line across the screen. It will flicker and try to display the picture. If you smack it you'll get a quick picture then back to a line. After about 10-15...


The single line means that the vertical deflection doesn't work. And since it is working when you kick the tv or has warmed it's clearly a bad connection - open the case and reseat the wires going to the tube coil.

JVC picture turns into a single line in middle of screen.


This is caused due to random falure of vertical scan circuits. It generally is caused by dried out capacitors or bad driver IC. Unfortunately it will get worse. If you fail to turn the TV off quickly you will burn a permenant horizontal line on the tube. Trip to the repair shop I am afraid.

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?
