Question about Mitsubishi Televison & Video

1 Answer

I recently replaced the DMD chip on my Mitsubishi wd-82740. When I turned the tv on - the picture was about an inch @ 1/2 too far up and about an inch to the right and the picture appeared to be slightly zoomed. My question is - can I use the service menu for corrections or will I have to re-orient the DMD board?

This unit uses a DLP (digital light processor) chip and if this starts to fail then you will get spots appearing on the screen. The DLP chip will need to be replaced.

SOURCE: Mitsubishi WD-65833: Reset system on my WD65833 after replacing the DMD chip. Now get a flashing code of 1-2. Any suggestions?

You are not the first person I have seen who replaced the display chip and had fubar after--1,2 is no error found.

You might want to do a little more research: Mitsubishi when changing the optical engine has a procedure so the engine can communicate with the digital circuit in the set--opps!

By the way the reset on the front is only a boot up for the set--set also has a hidden option menu for a hard reset of the entire set to factory defaults.

tried that one?

What is a dmd on a mitsubishi 73" tv


Howdy Mike-d. here,
I do not know what a DMD is on a Mitsubishi 73'' TV.
I did do a little web searching and here is a couple of things I came across.

From this website: http://www.tvserviceparts.com/Mitsubishi_DMDChips.html WD73833 ALL 4719-001997 DMD Chip, DLP, 1920X1080/XHD5, 0.65"/ DC4, TYPE X NON
I have no ties to these websites.
"I researched this and it was a DMD chip that needed to be replaced."
from this website: http://www.consumeraffairs.com/home_electronics/mitsubishi.html

Hope that helps.

60 inch mitsubishi comes on no picture only sound and then it will turn off by its self


Most mornons seem to think that your TV is a traditional crt projection when in fact it is a DLP projection set and does not have convergence chips or CRTs. Instead, your set has a DMD chip and a projector lamp that passes light through the light engine where a color wheel is and the DMD chip itself. Often times DLP TVs cycle on and off again when the lamp is starting to go out. Mitsubishi is well known for this. However, it can also be a symptom of the color wheel going bad as well or simply updating the software by downloading it from http://support.mitsubishi-tv.com/
Good luck and rate me when you can.

White dots appearing on Mitsubishi 1080p DLP tv.


Actually you must replace the DLP chip that is buried deep in the works of the tv. Unfortunately this can run into a nice lump of change. Do what I did. Perhaps you've heard the old addage
