Hello,
I have a problem with my Samsung TV.

Error description:

The power supply unit clicks when I switch it on. Background lighting comes on for about 1 second and then goes off again.

Everything has been checked:

LED strips from the lighting are ok. have removed and tested them.

I have already replaced many electrolytic capacitors with new ones.

Disconnected the mainboard flex cable. same error.

Disconnected both plugs for the background lighting.
nothing has changed.

I can't find a suitable circuit diagram either

Power supply unit: BN44-00633B

PLEASE HELP.

Complaint was no display, confirmed and I saw
this series USA model is very prone to backlight failure, so
ordered (8) new strips. Opened up the TV, and am testing the old ones. So
far all the ones on the right side are lighting up ok,
the set of strips connected to them via the connector side with the plugs
are not lighting up at all, even when I supply power directly
to the pins on that side.

I took out a set of the new strips, connected them together and tested, and
they are doing the same thing...whats going on? Thought these were all in
parallel.

If I separate the strips, the one with the connector plug seems to not
light. I have not gone through all the
new ones yet to test. I suppose they could be defective but strange how all
the ones in the TV on that side are not lighting and the others are.

Anyone have an idea whats going on here?
