7200 120mhz info needed.

Acquired a board from a friend who had some caps and pads come off. He sent board up to me and i fixed everything except one 47uf cap. It attaches to one via but there is another one on the other side of pad which may or may not have been attached to pad as well. Dont have a board to compare unfortunately. Thanks for any help.

Well, she turns on, but no chime or display of any kind, so either something isnt connected, or he butchered it elsewhere unfortunately. Does it need to be in a case to work? Grounding properly?

I have seen a lot of dead 7200 boards that will no longer be repairable. Even a complete recap did not work most of the times. I thankfully own a working and recapped 8200/120, which is in storage. If i get the time, i will make a photo of the board at the position that you have shown.

I have at least 5 dead 7200 boards myself and I have no idea what the reason for the high failure rate of them is. I suspect that the soldered CPU might be the culprit since some of the boards have a visually broken 601 CPU due to the heatsink pressing on the thin ceramic chip when stored without protection. But even when the 601 looks good, the board is often dead with sometimes no reaction at all, just the PSU-fan spinnig or a chime with black screen and no boot.
