I must admit, I'm feeling pretty ashamed. Been working on my PC-Engine Duo...I just fixed the dang thing yesterday with a video issue, and now I think I've really gone and mucked things up. As I was proceeding with an RGB mod, I plugged it in to test. I noticed a spark coming off of where I grounded both my obey region chip and the 6280 to the case. I knew this wasn't good, and immediately disconnected. I have no clue what I did to cause this issue, but would seem there is a short somewhere. I took off the RGB chip and checked all over the place for solder blobs or a broken trace or anything burned looking. I see no problems with my visual inspection, but beyond that I'm not sure what to check for. I'm no electronics expert, and mostly just follow instructions pretty well.
Did I totally fry it? I sure hope not. If anybody knows what to check that would be great, and if not, I would wonder about a good repair service so this thing doesn't end up in a trash bin while my heart breaks.
Thanks in advance!
