My 73' rear projection Mitsubishi turns on, an in

My 73' rear projection Mitsubishi turns ON, and in 30 sec screen blackens from the bottom up, leaving only about 5 inches on the top. Then, in another 30 seconds, turns completely OFF. Immediate attempt to turn it ON results into the immediate OFF. Unplugging from the power outlet for about a 1 minute just resets the above described cycle.

I just replaced the convergence chip in my Mitsubishi rear projection tv. turned it on and it worked for about 20-30 min then turned off. Now the only thing I get is a blinking green light.


Blinking green light is DM unit trying to boot up.

Did you remove entire chassis to do repair or just the middle board?


Another suggestion would be to remove front grill, remove inspection plate behind it, follow the wires that come down from front keyboard and disconnect the two plugs that connect them to the inside of the set.

This takes the keyboard and reset switch out of the circuit; you will still be able to operate the set with the remote.

If it works with keyboard out of circuit either just use it or you will have to remove entire screen and replace a bad microswitch on it.

73" REAR PROJECTION MITSUBISHI STARTED DOING 3D


Projection sets have two very common problems.

The first common problem is convergence

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped or bowed
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Mitsubishi screen replacing


You must remove the front bezel and frame holder to replace the screen. You will usually see the screws holding the from from the rear of the unit. Once you get the frame off, take note of the way the old screen is installed. There is usually a label on one side near the bottom; the new screens must be installed with the label in the same location. The lenticular goes on the outside (facing the viewer) and the fresnel goes on the inside facing the mirror. You will be able to recognize the fresnel, it has a series of concentric circles that are raised on the sirface of the plastic Be sure to rate this solution.Thanks!

Blinking tv


that model has some bad capacitors that will cause this. Does the power light constantly blink when it wont start? If so change the (4) 1000uf capacitors on the DM board this should solve the problem
