Problem is in the vertical deflection integrated circuit not the horizontal circuitry. Usually caused by cold solder or cracked solder joints at the pins of the vertical IC. Resoldering the pins will restore your picture.

SOURCE: Proscan PS35123-horizontal line only,sound ok

You have whats called a verticle swep falure. Its probably just the verticle output IC but if you dont know much about soldering or circuit troubleshooting ,you should leave this to the pros. Theres way to much Hi voltage inside these sets to twiddle around inside them. Also there are no consumer serviceable parts inside these sets as well, as they are all solid state, and my advice is spend a few bucks and get a pro to do this job for ya, as it can, and will, kill ya if your not careful.. Is it worth saving a few bucks??? Naawww Call a pro.. Good Luck

SOURCE: Black line running horizontally across TV screen

A line on an LCD, either horizontal or vertical usually means the video driver board is defective or the screen is defective, does it show up as black even on a dark screen? That means a line of LCD "shutter"s is not working and there is a problem that cant be fixed by a reboot or channel change. Bummer.

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.

I have a 2" black line at the top of the tv. And also smaller black lines across the middle of the tv.


Dear Jeff,
It seems like the Horizontal IC in your TV is dying. This and the Vertical IC is responsible for displaying images on your TV. (Look at your TV through your Phone Camera and you will see upward scrolling lines.This is the Horizontal IC in action.)
I would strongly advise you to get your TV repaired immediately.

Tv screen is black except for 1 horizontal line of color


The line is there because the vertical deflection unit - the one that spreads that line across the entire screen to form the image - has failed. Replacing it is a job for a professional, or at least an experienced amateur, and the parts will be quite difficult to find for such an old tv .

The vertical output ic needs re-soldered, look for a 5 pin ic connected to a heat sink near the flyback, re-solder the pins. If you are not up to this a local shop should be able to do this and it should not be an expensive tv repair.

Line across middle of screen, rest of screen black


The problelm is a defective vertical deflection system. Could be the amplifier, vertical output driver or whole printed board that supports the vertical deflection activity. It is considered to be a serious failure.
The cost of repair will be around $200 to $300.

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?

Black display with a horizontal white line in the middle.


Middle going across the screen from left to right??
This unit is plagued with bad solder connections in the comb filter board and flatpack underneath the comb filter board. These connections can cause any odd number of problems in video display. If it is that it's not expensive - virtually no parts. If it's a single line across the screen could also be the vertical circuit involved.
My suggestion is to have it estimated at a reputable shop and take it to them rather than the more expensive pu/del charges.
If you would like go to http://www.nesda.com/locator/state_search.php and locate a servicer from there. Kinda like going to the AMA to find a doctor...
Hope this helps!
