Re: samsung not working

The blinks mean nothing on a Samsung TV. They are normal. Have you checked other faults, like to make sure the PSU voltages are OK and if the backlight will power on by unplugging the connector between main board & power board.

Re: samsung not working

Something wrong on main board, check volt regs, and the CPU core voltages. Could be bad firmware.
