Re: CyberPower 1350AVR - Repair



Yes! My 1350AVR same problem, same repair, C1 22uf 50V. I actually ordered C1, C3 and C6 as well as the Viper chip, but, while waiting for them to arrive, checked ESR on the caps. C1 was bad, C3 & C6 good. Pulled C1 - it measured 460 nF instead of 22 uF. Substituted a 22 uF 160V (no 22uF 50V on hand).
Had to solder on wires (and heat shrink) and lay the cap on the board elsewhere as its diameter is bigger than a 50v same value cap. Works fine now. (If I had the other caps would have replaced them, too.) With thanks to those...

Hi, I'm Ed. Been replacing bad caps - and other misbehaving components in electronics
gear since the 60's. Still enjoy it - and I really enjoy other's "war stories"!
