    Help for LG L226WA-BN and FX5200 Recapping

    Hi,

    This my very first thread and i do not have experience dealing with diagnostics and recapping yet. If you can help me with my problem I will appreciate. I have a this 22" monitor since January 2007 and and it was connected to an non-over-clocked FX5200 agp video card from DVI until this summer. I had off screen once in a while and then suddenly screen started to not to work. I have kept it a side started to use a 14"....

    I have opened the LG PGU (2300KPG070A-F(LC) PLLM-M602A) recently and found out that it was using Samxon GF(m) Caps. I am planing to recap all Samxons with Panasonic FMs from a local supplier though I am worried about some stained parts.

    Also recently when I have tried a new screen 15" it started to have the same diagnosis, I have found out that my fx5200 has to be recapped as well.

    However my worry is with the screen circuit board, on the other side there are some stained parts. Can some one give advice about what to do?.. Since in both lcd and video cards capacitors are bad, are there any more damage on the cards you think?

    Thanks!

    Samxon GF series are problematic.

    That could be flux left over from the manufacturing process. You can clean that with cotton swabs and alcohol I believe.

      On your second photo underneath the plastic sheet. What is that large black spot next to C410? Did something short out?

        Those are usually just a foam sticky pad to hold the plastic covering inverter pins ,murder to clean off if you have to take off the plastic to solder

          That sort of staining is not uncommon,and does not usually signify any problem.As suggested,some alcohol, on a short bristled brush,will probably remove it.

              Thomas,The Inverter side would probably be on the other heatsink.Apart from the part arrowed,which unfortunately I cannot help you with,it looks as though you need to replace the Electrolytics as well !!

                I can give the following numbers I have the same plate capacitors and find not a diagram where they are.

                C202, C203, C204, C205, C206 since switched to an LG monitor and not if you have right now are the right and one exploded.

                Thanks in advance.
