Hi Adrian,

I replace all the capacitors on the PSU board regardless of whenever I service a unit. Unless you've got a problem with one of the cards (which I doubt), replacing the capacitors will give the replacement PSU an easier life...

If their resistance is quite low, that will shorten the life of the PSU.

Hopefully, that will get everything working reliably again.

Cheers,

Steve
