Samsung UE50F6500 does not turn on the stand by LED is blinking

Hello
I have such a problem. I can not start the Samsung UE50F6500 TV In standby mode by pressing the switch on on the remote control, the red diode starts blinking and a characteristic chirping can be heard. Before it happened, it was enough to unplug the TV from the 230 V socket or wait 2-3 hours and it was ok. Now, unfortunately, since yesterday, it won't join. I have inserted a short video with the glitch below. A colleague had the same thing, only that in a different model and apparently they replaced the switch with this diode. I was betting on a capacitor Has anyone had a similar case? Thanks for the information. Regards

I suggest checking the electrolytic capacitors in the power supply if they are swollen and the output voltage from the power supply, if it is 5V and 12V with the MB module plug on and removed

I have exactly the same problem as described above, it happened to me 2 days ago, so much that on the TV from 2011 samaung ue55d6000 so much that I don't even have a meter at home

Then put what you want.

Any basics ?? Have you done anything ?? any measurements ??
ps. there are a lot of similar topics on the forum ... just search a bit and draw some conclusions, check and then possibly create a topic.

(it would be appropriate, for example, to remove the back cover and, for example, disconnect the motherboard from the power supply and start the TV, i.e. simply insert the plug into the socket and something should help you).
The other friend is the same.
