@txydas Hi, thanks.

I tried to find the item on ebay. But I realized that here, in IRAN, sanctioned by Ultimate Satan Administration (USA), it is a tedious task or even impossible to buy such a thing through ebay or amazon or ... , because a TV WiFi RF module may be used in an imaginary nuclear warhead, according to them. LOL!

anyway, per the experiences reported in this forum, I tried to see what the module is. At the first glance, and more and more scope, no obvious fault was detected. everything seemed to be OK. So I just disassembled the module and the ribbon cable. I experienced that the TV had little or no sense to magic control. So, the module was not a thing that could be ignored. So I took some photos and reassembled them again after the only common remaining task, i.e. cleaning the module and connecting cable both at the module's and mainboard's header by a spray solvent.

And now, it is for 3 days that the TV has operated flawlessly. Everything is OK; Magic control, WiFi, Screenshare, No message, No pause or delay in the stream display ... I wonder what the bug was and wonder whether it would be coming back? Who knows? It was recommended to me to substitute the TV to another model or brand. It is not my decision for now.

So, It may be helpful if the users, who have replaced the module, say in please that if any similar tasks had been already done before replacing?

Thank you. My problem has also been solved. I disassembled the RF module and the ribbon cable and reassembled them again

I have same problem in my tv 43uj752v

I have a 43uj752v TV. There is a problem with the TV for about a month. The problem with the TV is that the message "unknown device is disconnected" constantly appears on the screen, and then the response speed of the TV is slowed down to the remote control commands and the mouse pointer is not displayed. and the TV wireless connection to the modem is interrupted. I updated the TV firmware yesterday but the problem has not been resolved.
Firmware version 5.80.15
Please help me
