Does anyone have a schematic of the power supply board of a Samsung UE40F6270 TV, type L46ZF_DSM / BN44_00616A ?
See photo attached.
Symptom: after 3 weeks of being powered off, our 4 year old Samsung UE40F6270 died 1 day after using it again. That is: when on standby, it does not turn on; there is the relay clicking on, then off (few seconds, random interval), and the red standby light flashing.
Voltage measurements on connector to main board (left bottom corner on photo) when switching on: 5V = 5.2V; 13V = 7.5V. So I suspect there's something up with the latter.
I am happy to replace capacitors but the closer I can get to the prime suspect, the better.
