Hello Everybody, I got this tv from a friend. It only lasted a little over a year and its been sitting since Jan of 2020...
I poked around a little bit, tested the voltages at the power supply I got 13.2 volts going to the main board. then because there is no picture I went to the T-con board and there is 0.11 volts at the fuse on the t-con board, I unplugged the t-con board the voltage stayed at 0.11 volts. I power cycled the TV and the voltage comes on at 0.11volts at the power cable for the t-con board.
I looked at another post on a different version of this TV 75UK6570PUB-BUSGLOR
By techmech: Hi Nomoresonys, there was an open resistor/link on the mainboard. The confusing thing was that there was a sense line providing just enough current capability to show me 12v open circuit with the T-CON disconnected, but when the T-CON was connected it fell to 9v.
I would like to solve this missing 12 volts without being a pepboys parts replacer... I'm really getting tired of buying boards to fix TV's.
I'll look into the shorted cap on the panel edge board after I solve the missing 12 volts for the T-con board.
