Where to start with a dead Thunder 24?

I have a Rev A Thunder 24 that is dead. No output of any kind. I'd like to try to repair this, but I'm not sure where to even start. Does anyone have any suggestions or info on what I should look for? I have an old 20mhz scope and a meter. Might have an old logic probe around here somewhere...

Any place to get schematics for this card?

Thanks

Take the easy route first, check the ROM and inspect the card under magnification first - check for missing components, scratches or loose pins

Do any chips get warm or hot when it’s running?

Does TattleTech see it?

Agree with Byrd, start with a visual inspection - post some high res pics here as other eyes can help spot potential problem areas.

Thanks @Byrd @joshc -- I'll start with a visual check and see if TattleTech detects it
