I have a red dot on a Coby TF-TV2001. What can I do to repair this?


If you mean you have a pixel that is stuck on and is always red, there's nothing you can do. The only cure is to replace the display. LCD displays sometimes will have a pixel (sometimes several pixels) that doesn't work properly. The manufacturers know this, and as long the display falls within their specifications for what's acceptable, they don't see anything wrong. These specs include the total number of bad pixels, the number of bad pixels that can be clustered together, and where they can be on the display. If you have just one or only a few bad spots, they won't do anything for you. If other problems develop, such as a whole row or column goes bad or a section of the display fails, then you can see about having them fix it if the warranty is still in effect.

What does it mean by dead cells?


I assume this is related to your LCD monitor.
I think you mean dead pixels. The LCD monitor has tiny pixel elements, one for each red, blue, green color and each one of these colored pixels are turnes on by a transistor. When a transistor fails then the colored pixel it controls does not light up. This is a dead pixel and it shows up as a tiny black dot.
If the screen displays a blue screen, a dead blue pixel will appear as a tiny black dot in the blue screen.
You normally would not notice a few dead pixels unless they are grouped together.

ViewSonic Optiquest Q7b 17" LCD Monitor has a fuzzy picture


LCD monitor needs to be fed with native resolution from the PC video out, this monitor native resolution is 1280x1024 @60Hz, try that setting to see if it helps before opening up the monitor to look for failed components.

THERE is two small bright patches in the screen


the two small bright patches are actually bad pixels.there is nothing to worry about as upto 5-6 bad pixels are fine.these bad pixels do not spread generally so no reason to worry.in case the number of bad pixels on the screen increase to more than 5-6 then you can get your unit replaced by the manufacturer if in warranty.

Black spot is growing on my LCD Monitor


It is the LCD itself failing, no repair for the LCD itself, the screen will need to be replaced. Likely cheaper to replace the entitr monitor
