Usually bad screens don't have "patterns", they get dead or discolored Pixels but not in distinct patterns. I would think this is more likely to be a failing graphics chip. try this, If you can plug in an external monitor do you still see the Plaid Pattern? If not, then it probably is the screen itself. If it is still there on the monitor then it is the graphics chip. hope this will help you diagnose the problem!

When watching movies on my computer, I am getting a weird line through the middle of the screen at times, also, when things are moving on screen faster, more lines seem to show. I guess they don't really...


i think your vertical IC ( if vertical lines are shown) / horizontal IC ( if horizontal lines are shown) of your monitor has damaged. you may contact a mechanic and change the corresponding IC

6 horizontal lines


I would look for a Vertical circuit failure. Most likely is the vertical output IC and or open resistor off the hv transformer. Definitely look for any loose solder connections around the Vertical output IC.
Hope this helps,

Ps 27123 have sound, tuning etc only small horizontal color band


Hello bdedrick708,

If what you are trying to say is that you have a 1/4 inch horizontal line across your screen, this means that something in your vertical deflection circuit has failed. This could be the vertical oscillator, the vertical output processor, the vertical coupling capacitor, or the vertical section of the yoke transformer.

If what you are talking about is a vertical line from top to bottom then you are possibly talking about a failed horizontal section of the yoke transformer.

Why so little about the horizontal section of the yoke? That is because if the horizontal section fails completely then you would lose high voltage and no line would be present because you would not have raster (screen light).

In any even check the yoke transformer first. Then work back from there.

I hope this helps,

Thank you,

I have a Sanyo tv with sound an a horizontal white line on the screen. Where should I start looking for the problem?


A horizontal white line on the screen means that you have problem on vertical section. It might be the vertical IC or other components near that IC.

HP Pavilion ZD8000 vertical lines issue


Hi,
In answer to your question. It may be a screen problem. as the screen has a Matrix of vertical and horizontal line configuration.
I,d suggest trying the laptop/computer on an external monitor or screen. if it works fine on an external. then it could be assumed that the TFT Panel or invertor has a fault.
if the picture/display still has vertical lines on an external monitor, then the fault may lie, with the Mainboard.

Process of elimination, before spending any Money :)
