SOLVED: Behind plastic screen looks to have dust on it

Hi, I have an Hitachi 42PD9700 plasma TV. When the TV is off you can see a mottled/patchy area on the top right hand side of the screen (this is still visible when the TV is on if you look closely). This...

Same problem. Gray clouds INSIDE the external (plexi)glass of the screen.
I guess either:
1 - Screen collection dust or some electrostatic phenomenon.
or
2 - Some coating peeling off.

1 may be solved by dismounting and cleaning.

Any solution you know about ?

My color is off on my whole tv i have a 52''projection toshiba cinema series the old big style and was wondering how to adjust the colors so they match up

Sounds like what was wrong with mine! Take the remote and hit menu, then scroll to the Video Adjust button, then adjust the "convergence" or the color tone, brightness, contrast etc. My repair man did this and it helped get the picture much more life-like. He said over time they get out of line and just need a few adjustments. He just charged the $50 house call. Good luck, hope you can fix it.

I have a philips HD rear projection TV 60 in. inside there are six adjustment knobs. Three are color the other three are for brightness contrast and hue. Which is which Left to right

If yours is a rear projection TV the adjustment knobs on the focus block inside are screen (red, green, blue) and focus (red, green, blue). The ones you are referring to as color are the screen controls and they adjust the intensity of the color from each tube. The other set adjust the focus of each color. They are also not intended to be adjusted by the user. Unless major components have been changed these controls should not need adjustment. That is why they are inside the TV.
