Oh, soldered in ULA!

Yep, so fingers crossed it isn't dead!!

Looks like a good place to start:

Cap removed and tested, and it's dead. Very dead, and certainly not 470uF. I expect the juices evaporated a long time ago, so time to order a replacement, along with one for the cap sat next to it.

You are very lucky!
It is the best board revision available.

I'll have to take your word for it as I am new to these machines. Sounds good to me though :)

Certainly, others I've seen have a socketed ULA, which I've heard can be problematic.

Very simple little machine though.

And spot what's wrong here.....

Another power board issue. At least I can fix this without ordering components.

EDIT: Aaaand it's fixed :)

Lovely cracked solder on a socket. :-)

Not totally obvious from the picture, but the joint on the right hand side was also cracked. I did all 3 joints in the end just in case, but the one closest to the plug end did seem OK.

Still need to wait for the replacement caps though, fingers crossed that'll give me power back.

I'd have thought that you'd have a 470uF in stock as they're so ubiquitous.
