Tv has different color corner


Not on a flat screen unless you have a very large magnet in that area---go to the video inputs and select one that is not used--look at screen and see if discoloration can be seen there.

If a LCD or Plasma with this issue the display panel itself may be bad.

Right side of screen becomes discolored and fuzzy after 15min


if its an lcd, it could be a bad lcd panel
does the menu or volume get distorted or dark too?
yes - likely lcd panel
no - video board (main board) problem

a technician would use a can of "freeze spray" to find the issue inside, by cooling down the parts until the problem goes away.. the part you froze to reverse the issue is the bad part.

Discoloration


I don't think you are posting about a LCD flat panel set, since replacing he lamp on these means replacing the panel.. If this is a rear projection set as I suspect it is, there are two likely causes.
1) Pull the lamp back out and clean the dispersion lens/UV filter immediately behind where the lamp goes. Clean it carefully, because it is easy to damage.
2) You have a bad optical block

Screen


Your LCD screen is broken this occurs from dropping the lcd or putting too much force/pressure on it. The black discoloration is is the liquid crystal leaking. It is repairable but the question is do you want to spend the money to repair it. A new lcd will cost you around $350+. You can also check ebay they might have compatible LCDs that might work for a lot less. According to the specs you need to took for a 12.1" 1024*768 XGA TFT Standard aspect lcd screen but beware not all LCDs with those specs will work. If your interested I am experienced in replacing laptop screens.
