Samsung LE46M86BDX...Intermitant Fault

[scooby-doo]

Hi....again

I have this TV and it has an intermitant fault...When you sometimes turn the TV on the backlights illuminate and the TV shuts down again...it looks a little like an inverter transformer fault..the trouble is if you leave the tv for 5minutes and plug it in there is no problem and wont be another fault with it, could last for 1 day or 2 weeks before it does it again.

I have checked for dry joints everywhere and all seems to be ok...the only thing someone maybe able to advise me on is on the "Left" Inverter (SSB460WA22L-Rev 4) has a random transformer middle of the board....I cant get any readings out of the dam thing...apart from that I am screwed

As always any pointers much appreciated
