Im trying to find replacement main boards for a QN65Q800TAFXZA inch and another QN75Q800TAFZA.

I CANT BELIEVE SAMSUNG NO longer making replacement boards for these.

My Samsung tv's are failing one by one and I cant get parts. TV's only 4 years old. TV's were not cheap like $4,000. Really sucks I cant get new boards. Cant find used replacements as well. Seems like if these are Only supported by manufacture with replacement parts for a few years then probably should NOT be buying the top models.

Both TV's same thing standby light on, clicks on and off. Unplug main board from PSB and back lights go on.
