There could be several reasons, If you have Warranty, best would be to take it to the point of purchase.

do any of the lights on the TV light up a solid color or blink? Please respond to this same post for assistance.

IS THERE ANY SOUND?? IF YOU HAVE SOUND BUT NO PICTURE, THE TV'S LAMP HAS PROBABLY GONE BAD. EASY TO REPLACE. ABOUT $120.

Try unplugging the power cord for 60 seconds and plugging it back in. We had the same problem and that worked the first time we tried it. The problem is back and, after some frustration, the manufacturer recommend updating the software. Contact your local Mitsubishi service rep. to obtain updated software and instructions. Good luck!

To which circuit section did you replaced the fuse? Main power retulator? Just understand, the fuses are used to protect the circuit and TV from any short circuit or over voltage. Without any one of these, no fuse will blow up. If it was due to over voltage, the set should work after a fuse replacement. But here, the fuse blow up again, means, there is some thing shorted component/s. Check which component is shorted, and replace it, before replacing an other fuse. One more thing to say is, never insert a fuse other than specified. The voltage and ampere specification to fuse, will be marked at the circuit board, very near to the fuse clamp. Insert a fuse of same rating only. Using other fuse, rated higher ampere rating, might make things worse.

Not quite sure what you are asking....if you are asking why the tv looks 3d or warped its a convergence problem. See the below article. If however you are asking about going from non HD to HD it just depends on if your model supports the higher formats http://www.fixya.com/support/r11932741-convergence_repair_dull_video_repair

It could be your Light Engine. However, I would first check a few things:

1. Make sure your Low Power/Lamp settings are adjusted so that they meet your brightness needs.

2. Make sure you used a Mitsubishi original lamp, as generics get chewed through fast and hard.

3. Try another lamp; sometimes you can get a bad one in the bunch.

All those things don't work, consider a Light Engine ($400 + for parts; $300+ for labor)

check to see if with a rear audio/video input you have sound (DVD etc)look in menu speakers are not set to off or externaltry the reset: Menu 1,2,3, enter.
