Hello all -

I recently acquired an Indy R5000 for a pretty good price at the VCF East convention earlier this May; however, when I tested it, both red and green power lights lit up for a second or so before the protection circuit seemingly kicked in, the system turned off, and a foul smell started filling the room. I assumed this was a power supply issue, but after opening it, I discovered it has a Sony unit installed - these supplies are considered quite reliable.

Tonight I finally pulled it apart to do a more in-depth diagnosis, and discovered a fried tantalum capacitor on the bottom of the motherboard, labeled as C602 by the reference designator. The cap is unfortunately so baked that I can't discern what its value is, and the capacitors nearby are all different values and sizes. Would anyone happen to have a bare Indy logic board laying around? I'd love to figure out what the value is and see if I can get the Indy to work again.

Regards,
CJ

Update: got the value! A very generous Indy owner sent a photo via Discord. The value appears to be 20v 4.7uF...solved!

Myth:

Sonys are reliable.

They blow mosfets pretty easily. The PSUs of both are old enough that the surviving ones are equally (un)reliable.
