Picked this TV up and they said it will no longer power on. When you plug it in the TV will flash the Samsung logo and power off with the standby light blinking 3 times and it will not power on. If you unplug the main board and turn it on the backlights do come on and the tv will stay running as well but of course with no picture so we know the backlights at least work. Any insight would be much appreciated. Below will be the voltages for the main board and power board while powered on
