I would suggest to locate a part that looks like the one on this link and re solder all the pins, also check for any high power resistor nearby the IC295890 and put some fresh solder.
Let me know if you need further assistance.

SOURCE: Thin Horizontal Line on TV screen

I had the same problem on a 36" Hitachi TV about 7 years old. After reading comments on this and other pages I went and bought a soldering iron not knowing what I was going to do with it.
After trying to find a loose connection with the power off- with no success, I then tried with the power on. Not the smartest move, but I was able to find the problem.
If you follow the colored wires (blue, green, red, yellow) from the back of the tube they will come together at a connector that plugs into a card at the bottom of the set. That connection was no secure. Since reseting that connection I have had the clearest picture since puchasing the TV new.
I am sure it is obvious that I don't have an electronics background, and I don't have an explaination as to why this worked. I just know it did. I hope this helps someone.

SOURCE: JVC 27" CRT TV AV-27BP3 display shows single horizontal line

I have a similar problem on my CRT computer monitor (AcerView 76c). It is an old screen and I think it is just at the end of its life, much like your TV. Having some background in physics, I would be pretty sure that the problem is with the cathode ray tube's vertical deflection system. The horizontal deflection electrodes are working while the vertical one is not. This results in a display of a single horizontal line (or in my case, a few superimposed) in the centre of the screen. Where both X and Y (horizontal and vertical) deflectors fail then the electron gun firing would result in a single bright spot in the dead-centre of the screen.

So really, we have no choice but to move on and buy a new set as repair is probably just as, if not more, expensive than replacement with a new device. Seeing as your post was in 2007, I hope you managed to solve the problem.

Best wishes,

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/

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.

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?

The single horizontal line is a problem with the vertical circuit. Look for a small flat id attached to a heatsink that should be marked LA7837 or something similar. Try resoldering the pins of this IC first. If that does not resolve it, replace the IC.

Keep us posted.
