Toshiba 52hm84 DMD board

No one seems to know how to find a DMD Board for a Toshiba 52HM84 HDTV. I am under the impression it is a set of boards/chips but I can't find anyone to answer my questions. Even Toshiba. Does anyone know what parts (number would be helpful too) make up the DMD board for this product.
Thanks,
wits-end

The DMD panel is made up of individual " Digital Micromirror devices" (DMD) one mirror per pixel. They are HD2+ DMDs which are the 4th generation DMDs. I dont have a part number but what is your set doing for symptoms? DMDs are basically small mirrors mounted on hinges that react to the digital inpulses so the signal can aim the mirrors percisely. Toshiba should have a replacement panel available. Let me know if I can assist you further.

Hello,

Your power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

I hope this will help in solving the problem.....

52HM84 Toshiba DLP with apparent failed lamp (replaced ballast)


I found R3 on the original board to be open, along with reading an open on CR1, D5 and D6. All the other transistors and the transformer check out. The only thing I have to do now is find out the specs of the diodes. The replacement board also had CR1, D5 and D6 open (R3 was OK). There had been some threads on various locations where remanufactured boards had bad components (the transistors were changed but not some of the other components).

52hm84 Lamp not working sometimes


Its the ballast. I don't know your skill level so I can't say wether you can or not. It may no longer be available. As of 3 month ago the light engines needed to be removed and sent to Toshiba to be rebuilt. The ballast is on the light engine assy behind the lamp.

Toshiba 52hm84 DLP buzzing sound after replace bulb?? no pic


You have bad capacitors in the power supply that took out the regulator, or the ballast circuit is defective. Not really a repair for the novice. Good Luck
