Black spots laptop screen


Pinpointed spots can be damaged pixels that no longer light up when energized. They cannot be repaired and you will have to live with them, or get a new display. Try to use the Color Adapter port to a standard LCD Screen. On the side of the computer is a small 9 pin (usually blue) port whereby you can attach a desktop monitor as an alternative to the LCD Panel on the laptop.

Red spot on LCD


Hi,
1) That red spot means that a pixel is stuck, actually it's very common on LCDs.
2 and 3) It usually occurs for a manufacturing issue.
4) The most of the time it doesn't mean that the whole screen is going to fail, but in my case I would take advantage of the warranty if the laptop is brand new and the warranty is still there.
Good Luck!!!

Red spots all over my LG LCD tv


I would check the LG website for a software update. I have a Sony and had white sparkles. After downloading their driver update, it fixed the problem along with a few other issues. Good luck.

TV issue


There are many causes for spots on top of an LCD rear projection tv, you are probably in the first two cases, both require part replacements and repair job.

If the spots are faint blue, green or pink shadows, then it can be a problem with the anti polarization panel placed on top of the LCD.

Similar spots (colored shadows) may be caused by a problem with the light engine, in that case the fix will be expensive.

If the spots are bright lights, like an aura, that is a problem with the color wheel.

Problems on the light tunnel can cause static gray shadows.

If the spots are static dark stains than that is lcd liquid, the LCD panel must be replaced.
