Hello there
Well this is my first post on this site!
I have a problem witht he above set, it has the Sanken 1H251WI (3501V00220A) PSU, LG p/n 6709V00010A.
The set was intermittently turning off, and it is now permantly off - so at least we have a proper fault to diagnose.
I can't find a schematic for the board, so am stuck to do much more than the basics. There is not even stby 5V present. There is DC being output from the mains side to the cold side, but tracking why it "dissappears" is a mission.
Does anyone have any info on these boards? (Tony I sent you an e-mail also)
Cheers
Ian

I had the same problem with my set.
Change capacitor C601 and C603.
Both 1000uF 10V

Brilliant!
Thanks Zica - it's all go now, will soak test in case other caps have ESR also...
BTW, this TV starts off with about a quarter of the screen showing black bled in horizontally from the right, and then the black washes out to normal picture towards the right. The pixels start up to green individually and then go normal.
I think I'll check the plasma HT supplies first.
Anyone seen this before?
Cheers
Ian
