Question about Mitsubishi WD-52525 52" Rear Projection HDTV

1 Answer

My power supply is not working

My lamp indicator light was on so we changed the lamp in out Mitsubishi wd 52525 and the lam indicator is still is lit. I took the back of the tv off and I can see when I turn it on the lam lights for 3-5 seconds and then off. I saw a resolve issue one of Fixya pages but am not sure what board it was refering too.

    is the V26 for the ballast?



  • jmontoya Nov 15, 2008

    so the V26 will have what I need to correct the power on the ballas?

  • jmontoya Nov 15, 2008

    so if I were to open the back of my tv again where would I look? We paid a technician to come out and he said it was the ballast board but I also saw him struggling to change the lamp.

  • jmontoya Nov 15, 2008

    I have the service manual I will take it off and see what I can find



  • jmontoya Nov 15, 2008

    I found the board that says power. the wires that are for the ballas are connected to this one, is this one the one I am looking for?




  • jmontoya Nov 15, 2008

    what do they look like?

    light pink little things?



  • jmontoya Nov 16, 2008

    ok looking at the diagram I have two that are bulging, one has something on the top of it. these are what I will need to replace with that kit?



  • jmontoya Nov 16, 2008

    Ok tv was working great and know.....we can watch about a movie and a half and the check fan light comes on. When I was doing this all to the tv I notices that there are three fans. Which one is it talking about, I cleaned all three of them when I took the back off to replace the capacitors.

That problem is usually related to failed capacitors on the power PWB. You can get a kit called the V26 Power pwb repair kit at the following link which contains the replacement capacitors and a a CD with instructions at the following link its listed under the repair kit category.

    Youre welcome, thats the usual repair for the V26 DLP when the lamp isnt the issue, they are famous for the Capacitors failing.

    The ballast hardly ever goes out on that model, its almost always the Power bord that powers the ballast which will cause the lamp led to turn red. The ballast usually wont trigger a lamp error if its defective

    The kit I listed above V26 Power Pwb kit repairs the power board which powers the ballast, there isnt any kits to repair the ballast, as the ballast hardly ever fails with mitsubishi its almost alwasy the power PWB which isnt the ballast.

    The power board is located inside the Chassis block which is all encased inside a large metal container. Most repair shops that are not famillar with mitsubishi DLPs will assume its the ballast, but its almost always the capacitors on the power PWB. I wouldnt attempt to remove the chassis block without the instructions or the service manual, as its a proceedure thats best done when you have the disassembly info in front of you.

    ok youre looking for the board called the power PWB it will be indicated where the board is located within the chassis block , its on the opposite end of the chassis in relation to the terminal PWB ( input Boards)

  • Sonny Berry
    Sonny Berry Nov 15, 2008

    yes thats the power PWB board that will have the failed capacitors on it there are eight cpacitors that typically fail on that board

    Heres a picture of an actual V26 DLP Power Pwb with some capacitors circled on it.

  • Sonny Berry
    Sonny Berry Nov 16, 2008

    Yes, the kit will give you the board location numbers of the caps say for instance C9A37 & C9A38 are 3300uf 16v, and they will include the correct rated Capacitors with the correct temp ratings as you need to use the 105 degree celsius capacitors. There are eight Capacitors that need replacement on that board, The kit will identify which ones they are by board location number and rating and they will include the correct capacitors.

    Youre welcome. I am fairly certain the kit will solve the issue with your DLP.

check the 2 3300 mf/ 10 volt capacitors on power supply board.
visible examination of these caps will often show the top of the capacitor bubbled up.

Lamps have been known to burn out the power supply to the DM assembly. If there is no visible damage to the lamp, your problem may be the power supply or the board. Good luck.
