What does white dots covering 2/3rds of the screen mean ?

My guess is that it is not economical to fix as it needs new screen. Unless it's under warranty but then you would not be asking. I had an off brand tv that I sold at my Radioshack franchise year ago. I had a customer get a tv with one white pixel constantly on. I replaced it for him. When I called the mfg, they informed me that this was allowable error in the b grade displays they used in their TVs. I quit selling them and put the bad one in my Rv. Still ticked me off when I watched it

Denotes a software trouble. Contact any service technician.

Look first to see if sound gone on all inputs---use a DVD etc connected to a input

Make sure in the menu speakers are not turned to OFF

last resort try the soft restore this model should have--menu, 1,2,3 enter

Set also has a hard reset but uses a different code I do not have.

Kindly adjust brightness/contrast/sharpness settings. If there is no improvement, this might require attention by a qualified service technician.

Turn the color all the way off---examine the screen to see if black and white or screen green in areas or whole screen.

The other possible issue is tint will not vary enough from green to purple when adjusted.

Two different issues--which do you seem to have?

You can Google the brand and model number for a free owner manual but on the set indicated it means usually the lamp is the issue.

you need to replace your dlp chip not hard to do

Tv under a year old call Misubishi for a warrenty repair.Flashes staus light mean could be any these parts have problems power supply board,Ballast board or the pojection lamp itself.

this problem is coming from your DMD board it looks like some LCD chips are getting stuck in the on or off position you need to replace the light engine system to fix this problem check this link out
