    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 timeβ€”like after playing a gameβ€”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...

    Samsung Syncmaster 740BF repair
    by soopacrucial
    Hi folks,

    I'm new here and was wondering whether you might be kind enough to give me some advice on troubleshooting the following problem:

    Quite a few years ago now, a couple of years from new, my Samsung Syncmaster 740BF LCD monitor starting playing up by making a buzzing noise and then the display would go blank. I seem to remember the blue power led would also go off when this happened but that I'm not 100% sure of. By pressing the power button I do remember I could at first get it working again but eventually the problem would come back. At the time I had read about...

    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...
