Thanks for your help Tom.
I guess I should forget about the power supply board and start looking elsewhere.
Im guessing the flashing LED is a fault code, but will probably end up costing much more than the power board.
Thanks again
I've just had a good play and found the 12, 5 and 3.3 lines.
the 5V and 3.3V are there all the time.
but the 12V is only present when the LED pulses on. (ie when you press the standby button on the remote) it then drops back to 0V when the LED pulses off. same as the 24V.
Thats a good plan, Though I dont think my boss would agree, I work 3 shifts, lol.
I wont get a chance to look now till sunday. I'll post any findings then.
Sorry Tom, I'm having to call it a night.
Was hoping someone might say "oh thats a common problem, try such and such"
I will have another look and post back when im more awake.
Thanks again for your help
So do you think I am barking up the wrong tree, looking at this board for the fault.
Might the fault be elsewhere on the TV?
I don't want to replace this board if its going to make no difference (like the repair kit).
Yes
It rises to 387V but drops off again,
Then, when the front LED flashes it rises again to 387V.
Repeats this cycle for a few flashes of the LED then settles around 330V once the LED has stopped flashing.

Hi
My name is Tristan and Im a maintenance engineer for a major car company in the UK.
A few months ago I had a cap problem with a Yamaha AV Receiver and successfully fixed it with help from a similar forum. I learnt alot during this process and have now found this forum after a similar problem with a TV set.
I am only after a quick bit of advice before I purchase a reconditioned 17PW20 V1
My TV (fitted with this board) will not come out of standby.
I have read many posts online regarding this board (including this one) and opted to buy the repair kit from e-bay ([url]http://www.ebay.co.uk/itm/261181194808?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649[/url])
Having fitted all the parts, I still have exactly the same issue.
