I have done some mods on my Game Gear (2 ASIC version).
first i changed th caps on the sound and main board. everything worked fine. then i tried a TV mod. sadly this one does not work i only get a black screen and some buzzing noises with very muted music...
then i did a LED mod which works fine.
so now i wanted to change the caps on the power board (where you plug in the power adapter and turn on the console) - there are three and i have some probs.
the big one:
is fine.
the middle one:
is soldered fine too, but i allways got a connection between the two solder points... can this be right? i even scratched between them to be sure there is no shortcut, but my multimeter was beeping...
this is question number one: can it be right, that there is a connection between + and minus of the middle capacitor???
the small one:
I desoldered the old one and use desoldering braid to get rid of the solder on the points. of course there where no holes (i am not good in desoldering i think
of course the solder points where destroyed after that. where can I connect + and - of the small cap. some alternative points?
