Sega Megadrive 2 broken trace?

Hello,

I've been trying to fix this megadrive 2 for a while now (Christmas present for a friend hopefully), it will power up but will not show a picture (though the channel will change automatically), the cables have been tested as has the game, and the contacts for the cartridge slot are clean.

I recently noticed that there is a broken trace (Highlighted blue) in this image: http://imgur.com/GJfswZd


I've marked in red where the trace seems to start and end (including the part on the underside of the board) but when I hold a wire to both sides (from the chip leg to the right side of the capacitor) I get a small flicker on the screen and nothing else, could someone please confirm or deny whether I have the correct start and end points? Or give me some extra information on what this trace is? It seems to go from the capacitor to the video/audio out so I presume it's at least part of the problem.


Thank you

 

You said it powers on? I means input, as in the power flowing into the system for the voltage regulator to convert the DC into +5v. If it lights up it should be fine. The most common fault of the Sega Genesis are faulty capacitors. Replace those.

 

Yeah it seems to power up fine, the light comes on and the TV automatically switches to the correct SCART channel. The power adapter works for my 32X and has worked for a megadrive 2 before.

The capacitors all seem fine, but the trace is definitely broken, I was just wondering if the path I've worked out seems correct. I assumed that if it was then the wire I held between the 2 points would have fixed it.

 

The trace near CE15, where a resistor goes looks a little corroded..

There looks to be three traces to the immediate right of CE19 that look suspicious but that may be dirt on the PCB..

From how I'm looking at it, it looks like the trace goes to a via next to CE15 and finishes on the other side of CE18..


edit: oh and the 3 via's next to the cart connector looks really bad, that may be your problem too!

 

Thanks for having a look, I should have mentioned that this is a picture that I found online, I haven't taken a picture of my actual board yet, I just thought it was odd for the output from what seems to be an amp to go to a capacitor.

From looking at schematics it seems that this line is actually the RF audio, so I doubt it's the cause of my problem now. I can't see any other problems with the board so it could be capacitors (they all look fine though). Looks like my friend is getting a late present
