I have a Mitsubishi 55"

NORMAL adjustments are made with the remote in the menu--if color looks skewed or even 3d go into menu and select convergence--with remote see if will adjust.

A better explanation of what the issue is might help and confirm model number if possible

I know these sets pretty well--worked on a lot of them when new and later--one of two possible ideas=

1. Either a odd convergence problem==confirmed or denied by going into the convergence menu (in customer menu) and selecting advanced which will bring up a grid of lines--if see the same issue (I will attach a photo of a Mitsubishi with this problem) it can be fixed.

2. Some sort of issue with the circuit board on the end of the Blue tube(you are missing blue=black) but usually in this set if that happens it is uniform and on both sides of the screen, not the top.

Let me know what you find.


I doubt it is convergence, but does not hurt to look--if the missing area was perfectly rectangular I would suspect up/down centering adjustment.

There is one other possible thing to try--we will leave it for last--set has 3 hidden menus and one is OPTION menu which allows a hard reset of entire set--sets everything back to factory except convergence adjustments which are stored in another area.

Check the pico fuses on the board. If one or more tests open, then likely the STK chips need to be replaced. This would mean a convergence failure.

Hello,

More then likely the red gun (bulb) had burnt out. It will need to be replaced. Unfortunately its not an easy process and should be done buy an certified technician. Contact your local TV repair shop for a quote.

Thanks

Try to describe better, is picture 3d looking or what is your problem?

Make a comment here OR IF YOU RE-POST THE QUESTION MARK IT "attention SD TECH" AND I will assist you.

I know the model indicated very well.

SD TECH

Your model doesnt have a bulb since its a rear projection TV . It has three picture tubes, However loss of video with audio still working is usually caused by a vertical output failure.

It has to be an HD DirecTV receiver for you to get anything about 480i. When you had an HD receiver you can select the resolution you want, up to 1080i.

2 possibilities. Either your convergence IC's are going bad, or you need to remove the front panel of TV where the speaker grill is and you will find a small box with 6 control knobs on it. Mark each knob so you can set it back to its original position if you forget, the set might turn off if you adjust too high on either color, if so, set knob back in original position and turn tv back on and try again.The if it works reallign your convergence and that should do it.

ok 6 hours is not long but i would deffintly say u have a power issue now with the box inside over heated and burnt out will have to be prfessionaly replaced

It has neither. It is not firewire capable.
