Could someone sullpy us with any information on repairing a Tripp-Lite power supply. It ahs no output voltage. When I switch the power switch on it draws about 1amp then it drops down to about 1/4 amp. on the 2 1000uf 25v caps I get 22.5vdc. D1 and D2 cathode 30v TP31 C-30v E&B 1.0v 2N3055 C-22v E-.60v B-1.0v 1n3492 22v On the regulator board Theres is a MC1723CP I.C. I'm wondering if the chip may be the problem.
