Hello. I've noticed that some of you had same problem with this plasma as mine.
It has Samsung LJ44-00101B rev 0,65 PSU with an 8 blink error.
I've read repair tips from atachment from old forum "Philips 42pf7320 shuts down after 10 seconds", But mine PSU is fine in stand alone.
When I plug it in, i have this error so I presumed, that other component is at fault. As this error belongs to bad Ve voltage, I've disconected power cable to X sustain board ( samsung LJ92-01029A) and power remains up with no error.
I've mesaured Fuse T6H250V on X sustain and it was faulty. I've tried other components on this board, but due to my amateur knowledge of electronics, I couldn't test evrything.
Then I've tried just to replace Fuse, but this was fatal to another two fuses on PSU :oops: and gave me 13x flash error. I've replaced fuses, removed one on X sustain and now I'm open for suggestions. :dubbio:
Have had someone similar problems with this X-sustain board( samsung LJ92-01029A)? What should I check on It? Should i remove FETs from it and test them or is short test enough?

Check or change C-8059(3300uF/10V) and C-8060 ((3300uF/10V) check allso SMD R-8094 (1M) near C-8099

Jordan already done it an I have a post on ELITE forum. Hope to see ya there. As I said, PSU works fine stand alone.
I've found faulty MOSFET 5N3011 on X main board. I don't know how could I missed it by previous check. Other components looks fine. I wan't to order it, looked at local sellers - no chance, Farnell doesn't have it.
Is there a substitute for this?
