Yeah, well, it's not perfect. This is for people inclined to FIX
electronic stuff. I used to repair monitors etc but don't have the
inclination anymore, let alone the time OR the room.

I have a 42" Philips LCD TV here which works well BUT ...
it only starts occasionally. What I have ascertained is that if
EITHER the master or slave backlight inverter boards is heated with a
hot air gun/hairdryer it will start up fine. Not much use like that
though. The low-ESR electros have been replaced, no change.

So I can't determine which of them is faulty, and at $50 apiece for
the replacement boards I'm not going any further down that road.
I need the space it is taking up.

Any takers?

Try replacing the PP cap across inverter transformer primary, worked
for me once. Replace cap with much higher voltage rating, as they get
hammered, I had to mount caps off the board for low height as the
replacements were much larger than the originals.

I appreciate the suggestion, but this set has been the subject of
extended testing and discussion at

and I really am sick of the sight of it.
