Hi everyone, I'm new - I'm having a problem that I can't seem to find an answer to after hours of reading this thread and searching the site. Apologies if I overlooked something.
I bought an MPC1000BK off craigslist, seller advised me over the phone that it had an issue he hadn't figured out. I talked him into dropping the price. I examined it in the sellers home, it powered on and the screen lit up (blank). I have some experience servicing PCs so I decided to take a chance.
Long story short, I discovered the memory check/play button function on my own, the unit appeared to detect the 128MB memory expansion but failed to pass memory check (resulting in "check memory" error message)
I re-installed the memory expansion and got a blank screen again, after several attempts I powered on the unit w/out the memory expansion and it responded by displaying an error message to the effect that there was no OS detected. I followed procedure for updating Akai OS and now the unit appears to function normally.
After closer inspection I noticed something a little suspicious about the memory expansion that I removed from my unit.
My question is this: does my 128MB memory expansion look damaged?
To my eye it looks like a component may have been knocked off the memory stick.

Aside from chip manufacturer the printed circuit layout appears virtually identical to what I have.
Whether or not I'd have to replace the Main CPU Assembly PCB in the event that the problem lies with the memory expansion slot is of some concern, I think I could do it myself. It would be a great relief if someone were able to confirm that all I need is a new RAM.
