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.
There is a class action law suit on this issue. Contact Samsung. Sometimes they will send a tech, sometimes you get a runaround. If you get the runaround, ask if you need to join the lawsuit. Just Google “Samsung TV & class action law suit” for information on it. It has to do with two underrated capacitors and they won’t tell me which ones. I got the runaround including me back to the same phone number I was talking to them on.
