Re: Samsung UN46D8000 dead - No led/backlight

Thank you for the reply.

Hummm I think the best way is change the Main board.

Do you know if it is normal this values in PINs 7 and 9?

Pin 7 - 12.77V (B18VS_PW)
Pin 9 - 12.77V (B18VS_PW)

Or they change to 18V when it is necessary?

Thank you!

Hi!

I have my TV since 2012. Today it is not turning on. No led, no backlight, nothing.

I opened searching for blown fuse, but it is ok.

If I try measures voltage in CN201 with the P28 cable connected in the main board I got all pins with 0V but the 4th pin is 5.32V. But if I disconect the P28 cable, the backlight comes on and I got the following measures in P28 Cable:

Pin 1 - 5.30V (B5V_PW)
Pin 2 - 3.33V (SW_POWER_OUT)
Pin 3 - 5.32V (B5V_PW)
Pin 4 - 5.32V (A5V_PW)
Pin 5 - 0V (GND)
Pin 6 - 0V (GND)
Pin 7 -...
