Sega CD in Dire Need of Help

I just recently got a Sega CD Model 2 and it has some issues. When I try to start it it locks up at the Bios screen where you can see the backround but it won't play the music or start the animation. I took it apart and there was a lot of corrosion on the board. I am working on cleaning it up but I wanted to know weather or not some of the capacitors could have gone bad and if they did what types would I need to buy to replace them. And I was also wondering if anything else could be the source of the problem.

It now refuses to even show that screen but I beleve that the fuse is fine

Here is a high-res picture of the board. I cleaned a lot of the corrosion off but it didn't help.

 

hi mate take the number ce on the boards example labbed CE1 220uf 16v
write them out or type the vaules out and then go on the net and look for replacements look for the 105c temp after listing all caps try to clean it up with alcohol frist before removeing the caps be warned the caps stink like cats piss i have done a few model one sega cds all had bad caps even some genesis systems every sega i have i have changed the caps even if there good just incase so lets see if you can fix your console i hope i have helped you out
its sounds crazy but i think its repairable

 

Looks like you've had a spillage, there.

You need to clean it up properly, especially the chips. Hopefully they're alright.

Doing a cap job certainly wouldn't hurt - they should all have values written on them. I assume you're in the US, just go to your local Radio Shack and they'll help, or order from a distributor like like MCM, Farnell, Rapid....

 

It's too far gone I found out. I took a closer look at the chips and on the sega chip to the left of the bios chip one of the pins are missing. I think that was my grandpas fault as he was scrubbing them down with a toothbrush and rubbing alcohol. After he did that it would no longer get to the frozen bios screen even. So I am just going to give up. Wasted a few dollars on caps already on ebay and that is gonna be a waste. Hopefully I can find another cheap one, I am gonna keep it around as the cd-drive surprisingly looks good.

 

got a pic of the board after cleaning i found you can use a Ultrasonic cleaner to clean pcbs

 

I'm too tired obviously - I read that as use a sonic screwdriver! :lol:

 

One of the legs on the chips is missing? Few words mate. Very fine soldering. youll need decent solderinging experience and solder one end of wire to the chip and the other to the board. It is not dead.one member here had the problem with a chip on a arcade board decent bit of soldering later and it fired up fine.

 

Yeah I am not that good at soldering. Im just gonna give up on it. I only paid a few dollars at a yard sale. If I get more ambitious who knows.

 

That isn't an easy job - it's not only the soldering, but you'll probably have to cut into the chip, too. To all intents and purposes, it IS dead unless you can pull of such a delicate repair. Even once that's done, there's still a fault.

 

If part of the leg is still there here can solder the wire directly onto that part of the leg which would avoid cutting into the chip.

Seg4f4n can you get closer pictures of the chip in question?

 

I've pretty much given up on it. I packed it away for now. Im going to keep it for now though as the CD drive looked to be in good shape. Maybe if I pull it out again eventually I'll try cutting into the chip and fixing it. Even if I could fix the pin it would still not boot properly which would lead me to giving it an alcohol bath and probably replacing the caps. Way too much work for me lol.
