LG50 PC1 -psu shorts Can't Post

Lg50 pc1d
I have trouble fault finding a fault on psu board YPSU-JO12B.

Changed shorted Q855 SD20N60 power fet

Symptom-fuse keeps blowing.



All other Power fets tested ok.

removed Relays RL101 & R102 & tested ok

removed C603 & c603 power capacitors and tested ok.

removed diode D601 and tested ok.

Last time I tested the thyristers TH01 blew up as well as blowing the fuse.



Any help would be welcome.

'Single spaced'

http://www.tv-forums.com/...;;page=unread#unread

'Double spaced'

Next would be triple spaced.

if all you can do if find fault with the layout of my thread don't bother.
I'm asking for help trying to find a fault on a psu not looking for correct grammar instruction.
