Re: Sony Vizo SV370XVT power supply not working.

H-man, is there any update on this issue? I am having a very similar issue and I don't really want to change a couple of MOSFETs and then have them blow again... Would you just consider ordering a new power supply board?

budm, basically you are suggesting replacing the 2 MOSFETs, 2 diodes, and the IC, correct? I will also check the resistors that connected to the Gate. Is there anyway of checking the IC to see if it has a short? Or do you just have to replace it and assume the short occurred? I am having the exact same...

Re: Sony Vizo SV370XVT power supply not working.

I am having this exact same issue as you. The fuse was blown and those two diodes on the board are shorted. Did replacing those MOSFETs & Diodes fix the problem? I am suspecting the exact same two MOSFETs as you say are shorted.
