    Can't find video test pin on Samsung PN51F5500AFXZA mainboard BN94-06194A.

    I have a Samsung PN51F5500AFXZA with 5 blinking lights. main screen comes on and and then vanishes. I checked voltage.. Replaced Power board and Y Main Board LJ41-10317A. Checked continuity on Ybuffer.
    So the only two boards are the main board BN94-06194A and the X MAIN BOARD. When i disconnect xmain. Same blinking issue but no picture.

    Trying to do Video test and cannot find anything close to the pins to short on main board. Pics attached. Mine has a cover on part of the main board.

    Any help would be appreciated.

      Thanks,

      Closeup attached. I was looking for something like bigger pins. I believe i have to short 3,4. Do I use alligator clips?

        Use a piece of wire or a paper clip between pins 3 & 4

            What issue? I'm still troubleshooting but if it's blinking lights then the general fix is replace capacitors on power board. Lots of videos links for that. I tried that and then replaced board but same problem.

              Help Needed: Samsung UE55MU8000 Dead - Possible Main Board Issue
              by Asraf Atb
              Hi everyone,

              Im looking for some advice regarding my Samsung UE55MU8000 TV with main board model BN94-11606C. The TV suddenly stopped turning on and now shows no signs of life at all not even the standby light at the bottom.

              Initially, I suspected an issue with the PSU, so I took it to a repair center. They tested it and confirmed that the PSU works perfectly, even on other TVs. Based on that, I started investigating the main board.

              I disconnected the main board from the PSU, and the backlight turned on, which seems to confirm the main board is the issue....

              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...

              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....

              Samsung UE48H6410 replaced Mainboard but backlights doesnt go on
              by max789
              Hello, I have a problem with my Samsung UE48H6410SSXZG with the main board BN41-02156A and the power board BN44-00709A. Everything seemed like this, the TV could no longer be switched on, the standby LED always flashed 5x2 times. Backlight was off and no sound from TV. Also made the flashlight test and there was no picture.

              I made the following tests:
              1. Disconnected the main board from Power Board = backlight works.
              2. Connected the main board and disconnected the T-Con = backlights does not work.

              So I ordered a main board from Ebay also BN41-02156A but from...
