I'm trying to fix a friend's Evel Knievel machine...
The MPU seems to boot correctly (2 flashes, one second, and then 5 others...) but nothing after that.
Nothing from the displays or the solenoids...
He's got a Skateball right next to it that's working properly.
Are the boards from 2518-17 and 2518-35 compatible? Can I try the Skateball ones on the EK to exclude things??
Quoted from srcdube:If it’s what I think you’re looking at and asking, the rectumfiers are in the backside of the board so they are up against the metal heat sink to dissipate heat... which is why they don’t use discretes on the top side like the repair job was.
Ooooookay !
I just realized I didn't know the English words for "diodes" and "pont de diodes" 
Quoted from Robotworkshop:I think that is pretty common for quick repairs. From your picture fuse 1 looks physically bigger than the rest but it just may be the angle of the picture.
If you go up a page or two in this thread you'll see a picture of a rectifier board I just rebuilt. It had the same bridge go bad as the one on your board that was replaced on the top. I replaced all three and added heat sinks. That small metal heat sink spacer under the board was removed.

It does look bigger indeed. I'll check that when in front of it.
That's some great work you did on that board !
I won't be as good as that.
Quoted from FatPanda:Or just get a new one for $55 from barakandl

That's a great idea for him to have a go on soldering !
