The fuse is good along with the other one.
Thanks again guys.
I have looked closely at the board and have not been able to see anything conclusive... but i have a couple of suspicions.
Suspicion 1: On one of the components have contact between the first three legs. Also there seems to be some corrosion taking place. Might this be the issue? See attached photo.

Suspicion 2: Another components exhibits what MIGHT be melt marks? Maybe it...Leave a comment:

I am not sure how to use the two urls?
Any thoughts on whether or not it might be safe to order a new power-board?

Based on the above observations, would it seem like a pretty safe bet that the power-board is at fault?Leave a comment:

Thanks a lot for the input!
STATE
LED-power: Connected
mainboard: Disconnected
LED VISUALS:
There is no light to be seen from the either back nor front. However there are no holes in the back chassis to peek through. So i dont know if the LCD-panel MIGHT be black and thus hiding the LED-backlight?
VOLTAGE MAIN CAP:
I am getting 389vdc over the biggest capacitor on the board (the main filter capacitor?).
VOLTAGE LED CONNECTOR:

I did my measurements while the power-board was disconnected.
The Power on_off waltage was 3,29v.
What does that tell me?......Leave a comment:

Thank you for the reply.
The screen remains black also when the logic board is not connected. (Is this enough to answer you question about the backlight or might the backlight be on without being visible onscreen?)
I have attached photos of the TV with no backplate, and the power-board placed where it should be (but with no cables attached).
Thank you guys in advance.
Best wishes

Samsung UE46ES5505KXXE power issues (i believe)
Hi guys
I am troubleshooting the power board (PD46A1_CSM BN44-00502A) in my samsung TV.
(UE46ES5505KXXE).
Do any of you know the correct way to "activate" this power-board, and might i need other cables that the AC-outlet connected in order to achieve that?.
I have been toubleshooting the board to the best of my ability from guides online by measuring output voltages on the pins going to the logic-board. However as i have been able to get very little response from the board i am a bit afraid that i might not have managed to "activate"... -
