1 Samsung qn75q7fnafxza Frame TV not turning on, has standby light
Hi, i have the samsung 65” frame tv qn75q7fnafxza. the tv, suddenly, only has the red standby light, but wont turn on. When pressed on, the standby light disappears for a few seconds and then reappears. Nothing happening on the screen. Already tried replacing the main motherboard and power board, but still didnt fix the issue. Anyone else have experience dealing with this issue? This TV has a one connect box. I have tried changing the one connect cable, and that didnt work, could it be an issue with the one connect box itself?

Patrick Chung qn75q7fnafxza should be a 75" TV not a 65". Going by what your image shows your TV should be a QN65Q7FN. Your power board should be a BN44-00940A and your mainboard a BN94-12832C. Double-check those numbers. Let's see if we can find out what is going on with it. You did check the connector from the power board to the mainboard to see if it sends power to the mainboard? You also checked the mainboard to see if that connector gets power? This is tough since you already replaced the boards so the next step in this would be that connect box but lets see if we can find more info on this model

So far, I have tried to replace the mainboard, power board, one connect cable, and one connect box. None have worked and all yielding the same results. I will try to replace the button/IR board next. After that, I’m not sure what else the problem could be

Did you find a solution to this @patrick? I too have the same issue. I’ve replaced the main and power boards and the one connect box. I have a new one connect cable coming, but I don’t have much faith.
What’s odd is randomly it started to work. I watched tv for the whole evening. I could even turn the tv on and off. Then the next day back to the same issue. So I know it’s not the LEDs.
The main board seems to make some power on noises when I press the power button, but then after ~2 seconds the noise goes away and then the standby light comes back on.

@oldturkey03 i called samsung and it ended up being the One Box. I replaced it initially from ebay, but i guess that box was defective too. After receiving a replacement from Samsung, it worked.
