    Samsung UN32F5500AFXZA turning off after 1 minute or so

    This TV is on 24/7 as it is mainly used to display photos within the house. Recently however we turned it off and now turning it back on leads to it turning itself off within a 1 minute or so.

    I have verified that no timers are shutting the TV off. I did remove the back panel to see if anything looked suspicious however I noted nothing.

    Is anyone familiar with might be the issue? Any simple steps I can take to identify the issue? When on, it's operating as it always did and looks great!

      measure the pins on the PSU connector where the cables go from it to the main board with a DMM. Write down the pin out name with the voltages you have measured with the tv on and then after it turns itself off. The ground lead to chassis GND or the GND pin on the connector.

          Samsung Series 9 - BIOS issue
          by Kjell
          After installing Linux, I can no longer enter the BIOS of my Samsung Series 9 (NP900X3C) laptop. When pressing [F2] during boot I simply get a black screen. Same thing when pressing [F10] and choosing "Setup" from the "App Menu" tab. Apparently this is a relatively common issue with Samsung laptops of that generation, but unfortunately i haven't been able to resolve the issue (yet).

          Things i've tried so far; reinstalled Windows 10, checked for redundant boot entries, tried to factory reset using the emergency keyhole, attempted to clear the NVRAM by physically...

          Samsung DM32D – Red LED blinks 5 times, won’t start (possible mainboard issue)
          by Nairolf
          Hello,

          I have a Samsung DM32D display.
          When I try to power it on, the red LED blinks 5 times and nothing happens—the unit won’t start.

          Here’s what I have tried so far:
          1. Disconnected the cable between the mainboard and the power supply → the backlight turns on.
          2. Disconnected the main T-CON ribbon cable → same issue as before, the LED still blinks 5 times.
          3. Disconnected one of the two T-CON ribbons to the panel (tested each one separately) → same issue, the LED blinks 5 times.

          From these tests, I suspect the problem might be on the mainboard. Could anyone...

          Samsung SyncMaster 740n Phase Control Issue
          by vincentedel
          Hello,
          I'm having an issue with the Samsung 740n's phase control setting. When I use the automatic adjustment, it sets the value to around 54 (with a range of 0-100), and the picture looks clear and sharp. However, after some time—like after playing a game—the text starts to look blurry. When I auto-adjust again, it may increase the value to 80, and everything becomes sharp once more. Yet, after a while, whether it's a few hours or a day later, the same blurriness returns, and I have to adjust it again.

          I'm using the Samsung 740n monitor drivers instead of the default plug-and-play...

          QE65Q800TATXXC Samsung TV Issue
          by Manucsl
          Hello.

          My TV is a QE65Q800TATXXC Samsung TV.

          Issue : When you plug the 220V, voltages are OK on the power board and you can hear the click from the relay, but TV is not starting when power button is pressed. Red led is blinking when you press power button. But no images or sound ( Back-light is off )
          Then if you disconnect the cable from the main board to the power supply, the TV back-light turns on.
          Any ideas to check would be very appreciated 😊

          After reading some posts on this forum, I suspect an eeprom issue so I bought a CH341A to dump...
