The fuse is fine, checked everything else seems ok too.......I'm gonna either have to send it in for repair or call it a loss. Can anyone here recommend anyone that does repairs for Supergrafx?

So Im guessing something went wrong on the console itself, does anybody know anyone who fixes Supergrafx systems?

So what AC adapter should I have for this console and at what rating? I was just using the similar one that came with my console which was a UK adapter so I bought this one which matched it at 9V 800MA so this is the one I got, if not what is the correct one. So would this cause my Console to blow or is it just the AC adapter is now a dud and I should get a new one at 1000MA or over? Just trying to figure out which is the real issue, the adapter or the console itself. Really appreciate the help guys.

Actually I made a typo there.... its a 9V 800MA Adapter I have.....is this still too small....I know someone said I need 9v 1000MA so is 9v 800MA not sufficient? And in this case is it blown or just I need a new adapter? It worked fine before.

Also I just noticed on the board that there is a fuse on the left side of the board that says 125v on the side, does anybody know what this does? Could this have anything to do with the unit not powering up if this fuse is no good?

Hello, I bought a PC-Engine Supergrafx a few months ago off ebay. I have had it for a few months and everything ran fine for a while but now the unit will not power up at all. I checked the video cables and they seem to be in working order as well as the power adapter to see if it was plugged in correctly. As far as I can tell it must be a power supply or board related issue because there is no LED light indicator for power to tell if the Supergrafx is getting power or not. The power adapter I'm using is the type you can adjust the tip I got from Radioshack.....9V 300MA which this what the Supergrafx requires as it did not come with the original. I opened it up I have limited board knowledge but I know the capacitors seem fine (Non-Bulging on Top). However the piece where the power cord plugs into, the wires that go from it to the board look like the insulation may have been burned a tad bit, could this be it because Im not sure if it was already like this or not? Not really sure what caused this, should I of used a downstep converter? I thought it be ok without it here in the US on this system. I'm not sure and if I were to get this fixed how much would it cost me to fix and does anyone know someone who works on Supergrafx systems? Just need a little help here Im hard pressed for answers to whats wrong, Any suggestions? Thanks a lot
