    Viewsonic Q19WB

    My monitor finally died today after it started having problems staying powered up a little over a month ago. No big deal, I used the advance warning to replace it before it died. I do want to repair it though to keep as a backup.

    Inverter ILPI-025 REV:E 2007.01.15 79069140

    I have fixed numerous electronic items but never an inverter module.

    I have the unit disassemled.
    C815 1000mf 25v (bulging)
    C818 1000mf 10v
    These seem to be the two most important parts to replace as they are directly connected to the switching transistors D803 & D805

    I also plan on replacing:
    C820 47mf 25v
    C501 470mf 25v
    C817 470mf 25v

    I was open to suggestions from people with more experience as to what other parts you would replace, if any? It seems silly to me to just go ahead and replace every single cap on the board and totally ignore switching transistors and various diodes and what about the ceramic disc caps?

    Anybody know the part numbers/values of D803, D805, C813, C814 ?

    Thanks

      OK, it's the wee, small hours, and I'm tired and grumpy.

      This should have been posted in the 'Troubleshooting Computer Displays' section.

      Inverter numbers are meaningless. The model number of the monitor is better. For better quality help, attach pictures. Others do it, you get the same privilege. Likewise, a better description of symptoms might assist us in assisting you.

      Replace ALL of the electrolytic caps, not just those which are bulging.

      Unless they are shorted, don't screw around replacing transistors, diodes, and ceramic caps.

      D803 and D805 aren't transistors, they are diodes.
