Question about Mitsubishi WD-52525 52" Rear Projection HDTV

1 Answer

Mitsubishi WS55513 Hello again.... Starting on this project again. I have the chassis, slider board assy completely removed from the wood housing...and am attempting to start my quest of finding a faulty component or a few. Like I said before, I did the DM board repair several months ago and put it all back together but got no power, no LEDS, nada. Perhaps I overlooked something, but while I have this boards assy fully removed from the chassis, I want to check every possible component that I can before I attempt to put it all back together. FYI.. I got a PDF of the entire service manual and schematic of that model but the schematic is so small I am having trouble reading it (my eyes arent what they once where) Any thoughts were I might pay strict attention to? Thank you in advance... -Richard (MetalDad)

Dnm board on 52 in dlp is bad


Hello.
Mitsubishi had class action because of this issue. The right way to fix this and several upcoming problems is to rebuild chassis. Chassis is a "sandwich" of 5 boards and they all have bad components. Unfortunately recall is expired by now.
Mitsubishi does rebuild it for $320 plus you have to pay technician for removal/installation (minimum $150). Add shipping (around $60) and fact that this TV need lamp replacement on regular basis (another $180-$220).
Common sense is to just stop investing money for repair of this bottomless pit and invest in new TV.
Regards.
Russ.

I have a 60" rear projection Mitsubishi Tv with a "wavy" picture in the vertical direction. What may be the problem?


Hello.
You have dreaded model that build around so called V-26 chassis. It's an epic story of Mitsubishi's bad engineering several years ago. They even faced class action about it and issued recall that (of course) already expired by now. You can search web for info on court case against Mitsubishi. This particular issue is caused by faulty components in Format board that is part of the chassis. The only right way to fix it - is to remove whole chassis (sandwich of several boards in metal enclosure) and send it to Mitsubishi to get rebuilt. If you will pay someone for repair of just this board - soon others will fail as well, one of another associated issue - after unplugging TV from the wall outlet you have green blinking light forever (reboot does not come to complete).
Right now Mitsubishi lowered price for rebuilding from $640 to $320 for authorized Repair Centers nationwide. Add to it labor charge for removal/installation (at least $150) and shipping (Mitsubishi assign number for repair and send special padded box that fits chassis) at least another $50.
Also take into consideration that lamp inside of your TV sooner or later have to be replaced. It is another $150-$225.
Calculate all of this together - that's how much you have to spend to watch your TV for another 2-3 years.
Common sense would be to cut you losses and invest in new one.
As for my experience - I've removed/installed those V-26 chassis about 1000 times or so while working for Mitsubishi Authorized Center.
Hope my knowledge of this issue would help you save some money.
Regards.
Russ.

Blinking green light of death on Mit WS55513. Changed the four 1000uf (35) capacitors on the DM board and it still won't work. Nothing has changed. Any help? Thankyou, sundayman1@msn.com


THEY are green and look like 1/2 watt resistor but will have amperage marked on them and the board--there at least 2 of them near the caps--if you need a photo of what they look like etower.766@netzero.net---Convergence chips will not cause the set to not boot up (the green light blinks and does not stop)


I do this here for free so if this information was helpful give me a vote here--good luck---if you cannot fix the receiver the only choice is to contact PTS electronics--you can ship it to them for repair/rebuild---part no longer is available from MITSUBISHI.

My Mitsubishi WD-52525 is only showing black and white rectangles on the screen. I hear sound, but there is no picture.


Check the white rectangular ceramic fuses on the FMT board. You blew one of them so there's power missing to some of the circuitry.

Mits WD52725 DM Board


Dan,
I would causion removing the DM board in this unit. It is buried and the real problem is that there is many capasitors across all the boards of the chassi assy that could go bad. Replacing the ones on the DM will not guarantee fixing the dreadful green Blinking
LED. The only way I have known it to be fixed properly is to actually send the chassi assy. to Mitsubishi for them to refurb it. The negitive thing is that it is exspensive and they will only refurb it through aAuthorized Misubishi Repair Facility.
Cost would probly be around 800.00 to 900.00.
I know it is not what you wanted to hear,
but that is mt take on it.
Hope this helps,

Red lamp light stays light


I doubt that it is the optical assy. it sounds more like a chassis problem either on the DM or the FMT board.

check out www.tv-techs.com
if it is a chassis problem it will cost about $250.00 plus shipping one way to fix the chassis

Mitsubishi WS55513 ---Flashing Green LEDs...and now NO POWER.. Hi...got the entire board / chassis out of the TV shell. Going to start checking individual components, starting with the mail power supply...


start by pulling the DM board (looking from the back it is standing upright on the left side in a metal chassis) and you'll probably find 4 bad capacitors (bulging on the tops is a good indication, If i remember correctly they are near the top right corner)
you can buy replacements here..
