Title: My SuperGrafx is DEAD?!
Post by: td741 on July 25, 2006, 03:01:54 AM
Let's see... I just shipped out my spare CoreGrafx in a trade and I also after all these years get my hands on a 1.0 CD System Card.

I plug in my SGX + CD rom, put the card in it and turn it on... except nothing shows up on screen!

I turn everything off, unplug the CD rom, put in a HuCard and turn it on and nothing.  

I don't think that I shipped the wrong power supply with the CoreGrafx as if I remember correctly the CoreGrafx power supply doesn't fit on the SGX or the CD Rom.

Anyone have any ideas?  Do people have the specs to the power supply?  I can try a universal one to see if it's just a problem with the powersupply...  But at the moment it doesn't look promising.

Which CD rom unit are you using?

I use the SuperCDRom unit.  Although I also tried the SGX without the unit plugged in with a game card.

I'm a little frustrated that the SGX doesn't even have a power light.  At the moment it just seems to be like the unit is unplugged, no glitch on the screen, or anything.

Open it up and look for the internal fuse. When you find it--bridge it. If it starts up, get a new fuse.

Thanks Seldane... Luckilly I didn't have to open it up (don't have the proper tools at the moment).

I was able to test the powersupply with my voltmeter and it was fried.  I was able to splice together the end with another power adapter and managed to get the system up and running again *yay*.  I was able to test my 1.0 CD System card and see the 2nd level of Altered Beast CD! OOOooo. :P

Now I better find more suitable replacement.
