Hi, for the last 1 month the tv is acting very crazy. The menu opens up for no reason. then the TV goes into demo mode and the volume is reduced and then increased. Sometimes the brightness control is turned down all the way. It's like a virus. I have tried reset to factory settings. Also i tried removing the batteries from the remote but to no avail. Do you think the PCB is gone? My TV just went out of warranty. :sad: What can i do?
