hi john
I went down a similar path, changing c141 470uf for a 1000uf, seemed to have had positive results but only ever seen one and the customer was at the stage where if it acted its self again it was going in the bin, so guess we will never know.
did find someone on ebay who new the secret of this repair and was offering a pcb repair service for about £50 I think, I contacted him and offered him some shiny coins for his secrets but he refused point blank (Meany, hope the Yule tide log slips from his fire and burns his house down)
, but you never know he mite have an Ebenezer moment over xmas and share his secret.
if not lets hope these sets soon pass into history

Hi daz
Think we may have discovered his secret! Will keep you posted if any more show up.

Interesting discussion going on here! I have a Prosonic tv with the same mainboard and stuck in standby too.

I'm going to play with some ribbon cables now, could you highlight me which one I need to unplug?

Hi
On the first set disconnecting the large white ribbon cable between the main board and dvb board got it started. On the others heating U696 on the mainboard with a hairdrier got the set going. If this is the case try adding the capacitor as suggested. Interested to know the results.
Regards
John.

The ribbon cable doesn't do anything (the very thin one).
The power led is on, but the screen stays blank (off).

I pressed some random buttons (tv/av, menu, pg+, pg-, vol+, vol-) and some kind of test program started running... flashing the screen on and off and displaying gradients.
At least this means the panel still works.

...If only I had a hairdrier!
