Artist Control Won't Power On

[Prodger]

Hi All,

I just purchased a used Artist Control, worked great when I was testing it out, but got it home and it won't power on. I got it to function once, but then shut it off and won't start up again.

I've read a lot about the L7 & L8 chips possibly being the issue; so I opened it up to see what was going on, and it doesn't look like my board has the L7.
But I do have an L8 that *possibly* could be the problem. (see attachment).

So, I'm looking for a bit of advice here. I'm ok to change out that chip on my own, but I'm not sure if it's the same one as was mentioned in the other thread a few years back.
