It's possible the mirror has dome dust on it from jostling during the move. W dried water spot will do it too. The front screen will come off by removing the screws on the bezel. Be extremely careful cleaning the mirror.Any scratch by a cleaning cloth (never use paper) will permanently ruin it.

Water spots after drying is an indicator of hard water (calcium-lime and other minerals) Bore water or other than town water. It may be necessary to use a light buffering cream after drying to remove the marks

Hi Kevin this type of problem needs to be serviced. What you see is liquid trap in the LCD screen that might damage other parts of the LCD if you wont fix it. If its under warranty call the Mitsubishi support.

if its an lcd be carefull plastic front layer on them it may have marked the plastic try warm diluted soapy water on a cloth but only damp not soaking or were water is running down the screen.

try remove your screens and clean it
if notwork your engblock is bad

Try removing the water hoses and find the screens in each end.. If clogged with gunk - that could be the culpret..

the only way to fix it is to replace the screen.not to hard a job as long as your confided enough to have a go of stripping it down to replace it.

Sounds like the screen burned out. Any water damage? Check the sticker on the phone (white box near battery) if not. Call your cellular provider and get the phone replaced.
