    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 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...

          Display issue Samsung TV UA65JS9000W
          by FourRunner
          I purchased a used Samsung TV model UA65JS9000W recently knowing it had an issue with the screen. When switched on the picture was bright both sides of the screen but a little darker in the middle of the screen. Thinking this was the back lights (side mounted LCD strips) I replaced these, however the issue is still there. I am now thinking it may be a TCOM issue, but am not sure, any advice on this would be appreciated. Also whilst changing out the back lights I noticed the the thick clear plastic sheet (maybe 1.5 to 2mm thick) below the diffusers there is cracking (up to 75mm) on the sides and...

          Samsung UE48JU7000 screen issue after backlight replacement
          by ScHAmPi
          Hi all,

          Because of two bright spots and a couple of dark spots I decided to replace the backlights in my Samsung UE48JU7000. See attached photos:


          I thought all went well, but after full assembly and testing it out it turns out not all is fine. The backlights are completely fine but I have some weird issues on the right half of the screen. Since I didn't really touch the T-CON board (apart from taking out the ribbons of the display and reconnecting them on assembly) it would be weird that the issue is with the T-CON board... But based on the behavior of the service...
