I actually found out what the problem was. I took it all apart and saw that either something leeked inside or something was wet under the a,b buttons and so I cleaned it and it works fine now but I wander what caused that. You think bad caps?

Yah it is a linx II,It could be cuz I did he a hard time getting it back in but this problem happened before I even took it apart to ...

Ok I just got an Atari linx from eBay the other day And everything works fine it starts up good the screen looks good. When I tryed playing a game I noticed that both the a and b buttons wornt working. For example I tried playing awesome golf and it says to press a or b to start. Well iv been pressing a and b and... Well a makes the speech disable and enable and that's what the option2 button dose. Idk what the problem is. I did already have it open and everything looks good and not corroded so idk. The reset button works but I noticed that it don't always flip the screen. So if anyone knows more about this that would be grate!

Herea a pic if the one with the line

Well I got a few of these GG's and I ended up with 2 kinda working ones. Ok so the one has a black line going across the screen. well it's not even a black line it's just duller the the rest. But note I've changed the caps and it's still there. Then on another one evening works good except the sound note I did change the caps on the sound board and even swapped out sound boards with a known good one, same result. It is making sound tho if I have headphones plugged in you can just barely hear it tho. Note I changed all the caps on the main unit as well. It's not a cap issue I don't think. Also I have like 2 others that just turn on for a second and shut off... I know that this means there's a short somewhere on the board. Well I've cleaned it up changed the caps and we'll , still same result... I've just about given up on these unless you guys can help.

I replaced the caps in mine and it still isn't fixed

Anyone know who can fix a sega game gear

Yah I cleaned everything and everything looks good I even tryed to resoldering the ics and still nothing. I actually have one that was worse then that and I had to replace some traces and it actually works fine

Well I do have this same problem but I also replaced all the caps but it still has this problem. Still can't figure it out ?

Ok so I recently picked up a Sega game gear and I heard alot about the caps going bad on them. Well I ended up replacing all the caps on the main,sound and the power boards. And everything works but the sound. It dose however make a constant clicking sounds when you turn the volume up. Is there any idea what it could be? I've already ruled out it's something on the main board cuz when I switched the power supply and the sound board to another game gear it all worked fine.

So what's the status

You got a link to there sight

Hay thanks I'll give it a try

Were can I get some at

I did unplug it and also tryed different controler and it still did it

Thanks for the help I'll give it a try and let you know of it worked ?

So I just fired up my ColecoVision for the first time in awhile and it all works like usual. I played it for about an half-hour and the the first player controller started drifting and eventually got stuck going to the right. I had a similar problem like this with my Atari 2600. It turns out it was a falty buffer chip. Any idea if that could be the problem here?

Well I put the heat sinks on and put it all back together and it all worked!! Thanks everyone for your help!!! I'm happy to get this working once again.

So yah I have it put in with the L7812 and it will work ok with the heat sink on but like if I leave it on to long it will get really hot and screw up but I don't have any thermal paste. What do you suggest the best stuff to use is? The other PCB has the same L7812 and no heat sink on it and it seams to work better / cooler. Mind that one the first pcb that I replaced just about everything on it except the 7805 regulator and the diodes. So you think it's just running hot cuz of the dioeds or the other voltage regulator? So the problem is definitely from the 7812. I know that cuz I did it without a heatsink and it screwed up in like 3 mins. Wile with the heat sink it's maybe 30 mins to an hour with no thermal paste. You think the thermal paste will make it last alot longer? Or could there be some better solution.

Yah ay-3-8900-1

Anyone know where I can get a stic chip

Well I'm still just wondering how long it'll be till they go bad again. Also I didn't know this but apparently on somegames it'll to to like a standby mode after so long. I know on astrosmash it dose.

Well it was a worry at first cuz I put one in and it instently got fryed. But then I noticed that it just shorted to the ground pin. But I did put in another one and it worked fine and it might've been the whole problem. Cuz iv played games for over an hour and it all worked fine although it got real hot after awhile. But it all worked

Success!! Although it was a rollercoaster of emotions I think I did find the problem. Well it's almost a successful run but I'm still happy. Ok I do believe that the main problem was that UA7812 cuz I've been playing it for about an hour but it did get really hot and eventually stopped working. But it was a much longer time then last time and this time it seams the cpu was getting hot so maybe that's another problem. But idk I'm happy that it dose run for a longer period of time. I am planning on changing out the that UA 7805 to but I think it can only get better from here ? also I Don't think it's something wrong with the logic board cuz I did get another logic board and I plugged it in to and it did shut off to do it's definitely something on the power supply/ or the transformer. I have a few more test to do but we are definitely getting somewhere ??

Pictures fuzzy but I think that's just cuz of the rf
