Hi All,

Just picked up a nice non-working CD32 and I traced the problem to a open surface mount resistor, R801, located between the power connector and on-off switch.

Problem is that I can't read the value as the print is worn/burnt off.  

Thanks!

Thanks Jeff!

I guess I just didn't look close enough at the schematic.... still learning.

I just used a piece of 30g a. kynar wire to make a jumper.... seems to be working fine.

Thanks again!

Thanks everyone for the help and and the great replies.  

My guess is that since the original power supply was missing, somewhere along the way someone might have try to plug in some other type if improper power supply and that was what fried that zero ohm resistor.  I made sure that the ATX PC adapter I made was right and checked and re- checked with my meter so I hope that I am safe using the jumper.

I love the feeling that I was able to save it from the scrap bin....to me it feels better to have fixed something nostalgic than to buy it new. :). Amiga mid-life crisis, hahaha.

I went to both Digikey and Mouser and located the 0 Ohm surface-mount resistors but I am assuming that I would need to know the power rating for the replacment.

Any idea what that would be?  1/8w to much or sufficient?

This is getting way beyond my pay grade. :)
