Hi guys,
I received my first CoreGrafx Iast week, and it was working.
I opened it to check for capacitor leakage, and there was some, so I recapped everything with ceramic capacitors (except for the 470 µF one).
After the recap, I only got a solid pink/orange screen, nothing else :(
I then tried replacing the ceramic capacitors with standard electrolytic ones, but now I get no signal at all — my TV doesn't seem to recognize the console.
Since I'm not familiar with this console, does anyone have advice on where to start troubleshooting?
Thanks in advance!
Hm, I don't trust ceramic capacitors as replacements for electrolytic models, it's above our pay grade... You shouldn't have done that.
I would clean the PCB thoroughly around the capacitor area, and check for trace damage. Check for corroded vias too.
There could be a bad trace to one of your capacitors.
However, depending on how much you moved around the card slot/gray connector cable, one or more of the wires for the gray cable could have disconnected/broken from the board. When this happens, usually one has to strip and resolder all the wires for the cables. It's usualy on the main board end not the Card slot part.
thanks Keith , it s probably not bad caps because , I recaped one more time with electrolytic caps to change ceramics one and no more chance.
I will try to resolder hucard wires mother board side as you suggested!
