      Re: Samsung hp-t4264,

      I would reflow the solder joints on all the heatsinked fets anyway. sounds exactly the same issue as the 50" version with almost identical PSU design.

      On that one, fault was on the FETs on the long thin heatsink in the middle. Gently flexing the board at that location induced the TV to suddenly turn off. reflowed and fixed.

      Worth a shot.

          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...

          Acer Helios 500 (PH517-51) - unexpected reboots when laptop is warm (cold solder joint issue?)
          by Mirenia
          Hi everyone,

          got an Acer Helios 500 Laptop (PH517-51) for diagnosing with a strange issue:

          The laptop runs for a while (1-2 hours, sometimes less) and then suddenly shuts completely off, like someone pulled the power cord and restarts immediately after on its own.
          If this happened once, then the laptop only runs for a few minutes until restart.
          This happens regardless while staying in windows or uefi or in a linux environment.

          At first I thought of a normal overheating issue, but as I monitored temps with HWInfo64, nothing seems very hot.

          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...
