Hello,
My Samsung TV does not respond with remote control, can someone help me, where is the problem?
Batteries are new all contacts Clean, remote works
that's a hardware issue, I'm sure

That model can work with external keyboard connected to usb, or a bluetooth keyboard.

With keyboard, you can update/upgrade firmware. before replace PCB check firmware upgrade.
