Question about Mitsubishi WT-46807 46" Rear Projection Television

Burnout ? wt-46807

Replaced the TIVO and the wt was working fine. Left the room, returned 20 minutes later and the screen was black with perfect sound. Tried changing the inputs with remote as well as from in front of TV. Was unable to open the home/ guide/ menu. Have only black screen. IS this fixable? naturally the five year warrantly expired last month! THE CABLE CONNEection was reattached to another tv and the "new" tv works fine. So, is the WT-46807 a lost cause? What do you/can you estimate what potential fees for repair? I am quite handy but do not think that I want to tackle this problem. I also dont want to be ripped off from a service company as well. A new set is expensive but for 350-600 dollars I think it would be worth fixing. Thanks for a rapid reply. Would like to get fixed ASAP Thank you Jon B

    Currently this TV is only being used with the Antenna B input for standard cable and for video games via the component 1 inputs. The xbox 360 games work fine through the component 1 inputs but through the antenna B input I have audio but no video. I've tried switching the cable to Antenna A with no luck. Any ideas?

There could be a Pip problem or the vertical sweep could have went out also so then the set shuts down the video so it does not burn a line across the tubes. Theres really no way to tell what is wrong or it would just be a guess, a shot in the dark. Call out an authorized repair depot and get an estimate. Good Luck

TV was working fine untl I accidentally hit the Menu button, then the screen went black except for the top bar that shows the channel, program name, description, etc...


Press the TIVO button. This should return you to the main screen. If this doesn't work, the box is most likely hung up. Unpolug the power cord, count to 10 and plug it back in. It will take a few minutes to boot back up, but this should fix the problem.

3 horizontal lines on Samsung LN46A650 upon start up. Causes the Tivo menus and on screen graphics to refract. Goes away within a 1/2 hour but returns when powered down and restarted.


I had the power board capacitors on my Samsung 46LNA650 checked, and the out-of spec/leaking ones (13 in all) replaced. The horizontal lines disappeared; but, the left side of the panel was dark for about 20 minutes (until warmed-up). I then found this forum/link that solved the problem! This simple fix was probably all that was ever needed - IT WORKS!!!!!!

Mitsubishi WT-46807 46 in picture bends and the blue red and white all seperates


intermittent convergence fail. suggest re-soldering the 2 convergence output ICs on the middle power board. they are the 2 large devices located on the largest heat-sink on the middle board(looking at from back) once you re-solder them as long as the aren't faulty internally you should be all set.
