Re: Dead Vestel 17IPS20 power supply repair (OK fuse, no shorts)

Just a note to say I also had the same problem with C397. It was reading about 250 ohms each way. Replaced and now TV up and running.
My 17IPS20 R6 board was pulsating on the first controller. Something was pulling it down.
The first IC controller is fed from VCC_Main while the other two from VCC. I found it convenient to remove Q216 (an ordinary transistor) from the board which isolated the other two controllers from VCC. This brought the first controller back to life with correct voltages on the secondary...
