Samsung UN32D4000ND flashing red light

The power board in the TV isn't working anymore (BN44-00421B).

When the TV is plugged in the led begins to flash.

So how did you manage to figure the Power Bd is the problem??

I previously took it to a Samsung repair centre and they said that was the problem

Can you tell us what it says in the box alongside the connector and then put your reading alongside. It looks like there are 14 pins

An example attached

Your chart made no sense to me at all, see DB chart again on how you suppose to report the reading of each pin.

He once read the second half of the pins on Cnm803p. It has 14 pins not 7. Since the secondary is powered up, A5v and PSON has to be there
