Repair Samsung UE32SES6100
problem after research DM852/DM854 power board short circuit
I had no replacements for these fast recovery NFE460 600 v 4 amp 75 msdiodes but i had U8100E 1000v 8 amp fast recovery and it worked well. i bend the legs to fit in the old position of the nfe460. Wach out for Anode and Kathode !
I disconnected the plug of the backlight, switched the tv on and measured power on the board connector J820. see the tabel beneath c9102. had no power
Switched off the tv and took the power lead off.
then i took an external power supply and did put about 60 v dc on the pins of L12/4 and the other one pins 6 and 8/9 of the cable that runs to the backlight. take care of plus and minus dc.
look at the screen while doing that and i saw the backlight light up !
So it must be the power supply.
