Hi everyone,

I’m trying to bring a 650 back to life. I already read different treads about but didn’t found answer or similar issue.

so it’s turning on, green led lighting, hard disk spinning…. but no bong and black screen…

I have a 4mb stick that run great on the LC3 and a new pram battery

I tried key combination control option p r but has no effect a all ?

thanks

stéphane

What happens with no ram stick?

Can you provide a good, high resolution, well lit photo of the whole logic board? Can you provide another of the corner where the battery is?

We're looking for tiny details, so it's best to get good lighting and avoid fuzzy photos.
