Mitsubishi WD73727 - dark 1" line across top of screen

There is a dark line taking up about a 1" space along the top of my screen. It is almost as if the whole picture is not being projected on the entire screen. I have replaced the bulb, but it is still there. Anyone have this problem? It is a Mitsubishi 73" DLP 1080i tv.

Thanks!

You need to replace the "light engine". This is very very difficult. You need to take it to a repair shop. But this will be very expensive. Around $1,000.00

I bet you are using a cable box or satelite receiver. If so check for aspect buttons on the remote that control these devices. I know comcast says "HD Zooom".

Sounds like a bad optical engine if you have the water color effect.

Hello
There are tow reaons for this fault. The first one is with the colour whell as you mentioned here. The second and most importan one is with its bulb itsef. Colour wheel won't cost too much. Just replace it first and see whether it helps you. If not, bulb may have to be replaced.OL

I have a dark line across copies


Whats the make and model of the copier?
One culprit might be the drum.  If you can take a look at the drum from your copier and you see black lines on it.  It could be scratches on the drum or it may need a new cleaning blade to clean the toner off the drum.

This sounds like it is a problem with the tv. Mitsubishi does have a problem with filter caps in thier regulator circuits. A repair tech will have to fix it.

Hello Adam...
