to get to the leds .this is what i found
there are four strings of leds.
each string is made of two smaller strings
the left section has 6 leds
the right section has 5 leds
the power supply has 3 pairs of wires going to the leds
i guess that the power supply is used in other models of tv
the top two led strips is wired in series to one pair of wires
the next two led strips each are fed by one pair of wires
all the...

Re: samsung un46eh5000fxzc no backlight HELP
yes i get over 200 volts at D1+ with the connector plugged in or not
and the powersupply shows no sign of burn marks , but the arangement of the leds has me a little confused, the connector is designated
D1+. S1-. S2+. nc. S2-. S3+. D1-. and the way the copper traces
are on the bottom of the board it looks like all three led circuits are in series
Right ?

power supply board . I have 210 volts at D1+ , 0 volts at D1-
