Wow realy bring one back here. I just got a Gamegear for 2.50 and popped in some games(cleaned them and the system first) I had and It works.....kinda. The sound is great. The screen on the other hand is kinda light black/grey. If you turn the brightness wheel all the way towards the bottom you can see the games at a crazy low angle from the bottom. I read the posts and I am using NiMH batteries. But no one ever cleared that up? What about the bad batch of resisters? Could this be the problem? Any help would be great!

The screen issue could be caused by bad capacitors, as described below.

Or it's possible that it's not getting enough power from the batteries, you could check with other batteries or with an adapter to make sure(it's the same as a Genesis 2).

And it doesn't seem to be isolated with the Game Gear either. Both the TurboExpress and the TurboDuo have similar problems (much more so with the TE). It seems as though there was a bad batch of capacitors in the early 90s; maybe someone could research this?

These are old handhelds, but yeah, there was this: http://en.wikipedia.org/wiki/Capacitor_plague

Now this is making me wonder if I shouldn't have somebody do a tv *and* a cap mod on a GG of mine. Hmm!

Thanx for the wiki article.

Thanks for that article. The screen issue definitely matches what RASK and I are experiencing.

Might be a good time to get caps checked out on both my GGs, my PC-GT, and my two Nomads...hmm. Would be spendy though.

Edit: It's worth mentioning I'm using a wall plug with this GG, too.

Is Omnedon still our best source for this sort of work? And does he do the TV output mod? :O
