1 I have no power, no power light.
I have a Samsung UN55H6203AFXZA US01 55-inch LED TV. I have no power, no power light. Nowhere (as far as I can tell), is there a legend for me to find which pins output the 5v PSON /STBY. Pins on the pin block going to the Main board are reading 1.1v As I am a novice I thought it best to just replace the Power Supply Board, but the new board does the same thing. I then replaced the Main Board and still no success.
This Samsung 55-inch is a mystery as I don't know where to test pins mentioned above to isolate the problem. The board is a BN44-00774A. Can anyone tell me where I find the STBY or PSON pins on this board? The only pins that have a legend, read 13v for each pin... There is a Joy Stick type button which is the power on switch and it has a very small board attached to the button, & another very small board for Wifi connectivity, (Smart TV). Can anyone help me out, or direct me to someone
I've watched dozens of You Tube videos, but still at a loss. Please advise.
Is this a good question?

Check to see if you are getting 5 volts to the IR (remote) sensor. You could have a short in it or on the joystick board in which case it would not allow the keypad or sensor to talk to the main board. If they each have a separate line to the main board you can unplug one at a time and try it manually and by remote to see if it becomes responsive.
