I've got a Centris 610 logic board that I recently recapped. I replaced all the leaking electrolytic caps with tantalums. It is working, mostly, though seems to exhibit some instability. I do notice that I don't get much for voltage across C50. Can anyone confirm if there is a DC voltage across this cap? I measure less than a volt and don't seem to have continuity between the positive terminal (or the via it is connected to) to any other voltage rail (that I've been able to identify).
Thanks! | Posted by: Phipli on 2023-03-12 13:09:04

Thanks! I'll double check tomorrow, but I believe that C50 is between 5v and gnd. | Posted by: RandomDamage on 2023-03-24 18:41:38
Yep, indeed it was 5v. | | 1 |
