    Plasma IPM rebuilding/repair??!

    Hello,

    I saw that some people rebuild a broken IPM modules for plasma Y/Z boards. It's based on disassembling IPM module and replacing fried FET's and components. Some try to fit standard FET's inside IPM housing and others put FET's outside connected to IPM board with wires. Possibilities are endless, and it sounds like lot of fun ;-) I see some of IPM's are filled inside with some kind of epoxy or silicone, it looks hard to clean it to expose components inside IPM.

    Did anybody have some experience with IPM rebuilding/repair? Any success??

    There are few tries on this forum, but best resource is this Russian thread, which I don't understand a word. Pictures are impressive!!

    Use google translate. It isn't perfect, but it should give you some idea. If you use Chrome browser, it should ask if you want the webpage translated (assuming you have that option enabled).

    BTW, one retiredcaps bonus point for pictures of your multimeter in the other thread.

      Retiredcaps, thank you for bonus point. Are these bonus points official on badcaps or just your personal compliment? Well, I didn't think I'll end up as BadCaps medal collector ;-)

      About IPM rebuild/repair, it seems few FET's and few decent diodes cost more than whole IPM so repair is not profitable as there is no grant it will work. But to make a whole new pcb with control circuitry and separate FET's and diodes on large heatsink as a direct replacement for IPM sounds like cool project and fun. Of course, not for my old pitiful 480p TV but maybe for some popular fancy 50" HD plasma to make it fail-safe...

      Cheers!

        The latter.
