Re: Samsung / Hansol BN44-00428b
It is edge lit LED backlights setup, 4 LED strings total per diagram (from looking at the A and the B version, the component designators are not the same but using the same setup).
I still do not understand by the LED does not even flash on once before going into shutdown, it will have to detect that one or more of the LED strings are not working by trying to fire up the LED, if it detect shorts or open, then it will go into shutdown.
You may have to remove the LED strings and check each LED, you should also check to see if any one of the wires leading to the LED strings are shorted to the chassis.
