Re: Samsung UN55JU6700
Yes I have samsung tv was working on I would get click too with t-con board also .It turned out to be a power supply. I took my board out look for anything visually that looks bad. Mine was a bad electrolytic compacitor. The only way I could tell is there was a black burn where the comapacitor got hot left a black spot could easily see.Later I looked and saw the compacitor was black too other side of board.
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

Re: 50PA4500 safety
Always use safety when working in tv. It will have two sides on the power supply board hot and cold. HOT SIDE IS AC AND COLD IS DC. OR IT WILL SAY PRIMARY FOR AC AND SECONDARY FOR DC ON THE PCB LOOK FOR WHITE LINE .TV VOLTAGE CAN KILL SO DONT touch the hot and primary on any pcb. There live discharge is about 30 mins but not all capacitors can hold charge even after 30mins .Last edited by Packard93; 08-07-2019, 02:02 PM.

N8-42P650A11 plasma power returns to normal if i remove ribbon on middle board
Power returns to normal when I remove the that middle board disconnected my voltages go to normal .The one in middle that describe looks like a tcon board . I get multiple clicks with all boards connected . But when I disconnected that little rectangle one which looks like t-con board my voltages come back but when I connected them back I can see the voltages cycle up and then down to 0 . The middle board disconnected seems to be my issue I guess . When i disconect the ribbon cable test the 5.3 volts I get them . After connecting the board back I get a series of relay clicks of 5 and the red...Last edited by Packard93; 07-25-2019, 02:04 AM.
