Hello, folks!
I have an Samsung LCD TV with defective powerboard BN44-00369B.
First, it was a defective STF13NM60N transistor (QP801), so I replaced it. But now, there are no Backlight and picture.
There is no power to CNI801 output, even no power to the TI801S.
To the CNI803 there are:
Pin / Voltage
1 (12V) / 12.88 V
2 (GND) / -
3 (GND) / -
4 (LD) / 0.00 V
