I have a Samsung UN75H6300AF that will not turn on. The caps on the power supply look good, fuse is good and none of the circuits appear burnt/damaged.
I measured voltages on the P/S board and I am getting 13v even when it should be in 8v standby. One of the AC/DC converters that should be reading 18v is reading nothing.
I disconnected the boards one at a time and when I disconnect the main board, the backlight comes on, and the converter will then read 18v.
Next steps? Should I assume the main board is at fault?
