I had the same problem, but managed to repair it myself! There is no need to purchase a new
Power Supply! You can service the faulty PCB yourself, or give it to a Tehnician to service for you.
If you want to try service to yourself, here is how,
On the PCB marked QPWB11326-1B-4 you will need to do the following<
Replace the following Capacitor's, CS704(Most important one), CS705, CS706, CS707, CS708, CS713, CS715.
Replace the TOP210PFI IC marked ICS02
Replace the PC123 OPTO marked ICS03
Replace the TL431 Shunt Regulator marked ICS04
This solution should work! email me on [email protected]
if you have any other requests!
