Hi and welcome to FixYa,

Initially, it would seem to be heat related and/or a cold solder issue. I doubt very much if any major component is defective, at most probably would be a capacitor in the main B+ line leading to the HOT (horizontal out). But that has to be confirmed visually and/or a voltage check on initial power up. best approach would be to open the rear, do some voltage measurements before warm up and after warmed up. Compare these readings and reference the Service Manual. Of course special care and attention since you would be working on a live set.

Check and perform preliminary visual or necessary inspection. Pls post back result(s). Good luck and Thank you for using FixYa.

Auto-dimming problem


It depends of the set--may have a light sensor built in and if so when light in the room changes the brightness on the TV and contrast will vary.

Dim picture


First, try adjusting your Brightness and Contrast in the Video or Picture settings menu. If this doesn't fix the problem, your LCD Back Lights may have burned out. You will need to either replace the Back Lights, or the LCD screen if they are built-in, take the TV in to a TV repair shop, send the TV back to Mitsubishi for repairs, or replace the TV with another.

Has fuzzy spots all the way across the screen and just scrolls up


Is the picture fuzzy whether you are waching tv or a dvd or a tape. If it's only fuzzy on tv or dvd or tape then it's the source. If all inputs are fuzzy suspect a bad tv.
