    Thank you for your help... unfortunately I am unable to check the screen by hooking up to a TV... for some reason the s-video cable is not making connection.... anyway I am in Mexico so will have to wait until I return to the USA on June 3. I do not think it is still covered under warranty... it is probably 2 years old. Thank you.

Those issues can be caused by either loose connector cable between the display and the motherboard. Or a fault in the video adapter / card. Last possibility is faulty display panel.

To find out if the video adapter is the cause you could connect the laptop to a external display a crt or lcd (the display that is used by your desktop pc, you should have a connector on the laptop for somekind of external display)

if the horizontal strip appears on the external display then the fault is internal on the video card, and there is no home fix.

Is the laptop covered by warranty?

Most of these causes can't be home repaired, the loose cable can be easyly repaired at home, but a faulty motherboard / video adapter is very difficult to repair. The lcd panel also would most likely have to be replaced if it was the cause.


If the lines appear after some time of using the computer, they could be a sign of overheating or damage from overheating.

    Okay,

    if the problem only happens when you have been using the computer for a while it could be overheating and you might be able to help the problem by cleaning the fan with canned air and make sure theres no dust on the fan / its heat sink.

    you might also want to try a laptop cooling pad that goes under the laptop, those two things might help it enought so it doesn't do it constantly.

Sony FD Trinitron WEGA KV27FS100 horizontal lines across top part of screen


Check and replace all electrolytic capacitors in the vertical output section circuit. There will be 5 or 6 of them to replace. Replace all at one time. The fault you describes here is technically known as 'vertical retrace lines'. Visit the site named 'Electro-help' for more details. Click this link. View it in 'Flip card' option, which can be selected from the drop down box menu by the [Sidebar] tag, at the top left corner of the display window. It will make search easy. There are more than 990 posts to different brand TVs now. Sometimes, you might get some more details from there.

Hello, I bought an LG 47LH50 HDTV exactly 1 1/2 years ago. Black horizontal lines suddenly appeared one night after getting home from work. Over the past two weeks I've seen it go from 3 lines, to 4...


Hi, I purchased the same model in November 2009. About 2 weeks ago a single horizontal line appeared. Each day another appeared until today when the video went out. Now it displays bands of vertical colored lines like a pastel colored rainbow. Did you find a solution to the problem?

Red/Orange horizontal lines


it could be that the tv convergence circuit is going bad. One shure way of finding out is to go to the tv feature menu(picture,audio etc.) and select the customer convergence setting, you should get a cross hair pattern(cross in middle of screen). that cross should be white and by aligning the red or blue colors they should move left, right, up or down

I have a horizontal color line across the screen...have sound .This is on Video 1


If you are comfortable working inside the set and can solder, try resoldering both the vertical IC and the input jack connections. The vertical IC will be a small flat IC attached to a heatsink with about 9-11 pins. It will be marked LA7837 or something similar.

Let me know the results.

Hitachi 51SWX20B Convergence problem


Solution:

Your TV has a convergence problem. Here are some of the most common symptoms.

Screen looks 3D
One or more colors can't be adjusted when using the convergence menu.
Screen is bowed in or warped.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence or magic focus section.

Try to adjust the convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

Its a fairly easy fix on the Hitachi sets.

You can get a repair kit that includes all the parts from www.TvRepairKits.com. The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc.
Everything you need to fix it yourself.
