    Samsung PN51f4500fxza

    I have a pn51f4500fxza that has no standby light or will not power up.

    I only get 5.1 volts on standby and 3.6v on ps on. The two main caps each have 171 volts.

          VS/VA are both 0v.

                  Compatibility of main boards between different variations of samsung MU6100
                  by JSin21
                  Hoping someone here could possibly help. I have a few questions in regards to compatibility with main boards. But I'll give a quick short run down on what's going on first;

                  I have Samsung Smart TV UA65MU6100WXXY version DA01

                  Now years ago it started intermittently playing up after a lighting strike. Lighting hit the block of units i was living in at the time. Ever since that night the TV started having a mind of its own, It would randomly turn itself off or on, and all inputs stopped responding like HDMI, aerial, but USB still worked. Anyway, over the next few months...

                  Zombie Samsung UN55NU6900F dead / no standby voltage - randomly came to life after hours of troubleshooting then died
                  by tvguy12012012120
                  This is my first attempt at troubleshooting a board like this, I know I could just buy a new board but I'm curious to figure out how this works. I've been testing different components in the evenings this week and I think the problem is with the IC failing to start up for some reason. When the board is plugged in there is no standby voltage.

                  Then today it randomly sprung to life like a zombie but shortly died thereafter. I have no idea why it would have done that and its the first time I've seen it running. I discharged capacitors on the board last night, then it was sitting today....

                  un60j620dafxza - Samsung No Display Problem
                  by stylishconsultant
                  Hi All,

                  Need help.

                  I have a samsung un60j620dafxza led tv. When I plug it in it has no display, no sounds, and no standby lights.

                  So I opened the tv and disconnected the power to the mainboard and the backlight powered up. This according to many people says that this is a mainboard
                  problem. I checked the voltage coming from the stb and I read 1.3 volts on pins 1,3,5 and 7 which are low volts instead of 13 volts which i think the lcd panel
                  might be drawing too much power from the power supply that it prevents the right voltage going to the mainboard....

                  Compatibility of Samsung Y Main boards LJ92-01732A no rev vs rev AA2
                  by Yanleb
                  Hi, I did look everywhere to know if Samsung Y Main boards LJ92-01732A without rev marking is compatible with LJ92-01732A rev AA2.

                  If they are not compatible why did Samsung give them the same part number to begin with?
