Thanks for the advice, this was my first go at repairing a board like this. Probably should have tried something that wasn't so rare!

Well, I made a bad mistake while soldering and yanked a couple pins out of the Cuda. The only way this board gets salvaged is in the hands of someone far more capable than me. Thank you all for the suggestions and help, I appreciate it!

Pin 28 is the sad pin at the top left of U29, with nowhere to go.

I pulled the Cuda (U29), cleaned, and refreshed it, but no change. The pad for pin 28 of the Cuda is completely gone, any suggestions on where I could jumper it to? Schematics of similar boards suggest it pins out to XFC, but I am unclear what that is

Glad to hear it worked out! Did you have a replacement for U29 or did you just clean it and re-attach?

Let me know how that ultrasonic clean goes, I don't have an ultrasonic cleaner yet but was considering one. At this point I am suspecting bad RAM or the CUDA, since I still have to jumper pin 27 to 5v to get soft power at all.

I cleaned up the area around the onboard modules, and re-flowed all of them, but no change. The behavior happens without a ram stick, and also with a known working stick.

Hey all, Trying to bring this Mac TV back to life. I had to jumper the Cuda just to get it to soft power, now it does and then gives the normal chime and then an immediate death chime, and stays on a gray screen. It has been recapped, ROM and RAM SIMMs cleaned and re-seated, but I can't get it...
