Re: Black screen LG 43UK6300PLB
Those are the panel boards that distribute the voltages and data out to the panel. Sometimes they are also incorporate the t-con on the panel boards.

Re: Samsung UN55H8000AF - No Picture, Working Backlight, Replaced T-Con Board
I believe TV will work without t-con connected to chassis. And there are grounds going through LVDS cable, So maybe a problem on mainboard or cable.

Re: Samsung UN55H8000AF - No Picture, Working Backlight, Replaced T-Con Board
You have 3 leds on but dim. T-con change did nothing and your 12v is steady. Seems like bad ground.

Re: Phillips 55PFL5602/F7 T-Con failure?
So, you basically have only 12v on t-con with cables hooked up? And you checked voltages when you removed cables and same no voltage?

You could check those test points for shorts. You could cut the traces and check the voltage. Check the caps around the ic. Check for 12v to the ic.

Re: LG 55UB8500 no picture.
Why are you giving picture of t-con? You said you have no voltage going to t-con. Thus you need to look on main board and find where you are losing the 12v.

Re: LG 55UB8500 no picture.
How could I have location? You provide no pictures or schematic. Trace the 12v from t-con terminals back to trans. that controls the power to t-con.

Still learning, but I think on PNP that gate will need to be negative (-1.7v) in respect to source

Not sure the t-con is on the panel. Probably a short on board or panel causing reboot.
