    Weird Display Behavior -- LG 49UH610V

    Hi,

    I've got an LG 49UH610V that has some weird display problems. The LCD panel itself doesn't seem to be broken but It keeps alternating between a good image and a bad image around every 2 seconds. (so it seems fine for 2 seconds and then switches bad for 2 seconds and keeps alternating, see video attached)
    At the top of the screen there is a pink horizontal line which isn't visible in the video, this line never goes away it's always there no matter if the screen is currently "good" or "bad".. when I disconnect the left side of the Panel from the T-con, it only shows a solid image of vertical black and white bars however when I disconnect the right side, it shows the same bars but every 2 seconds these bars start to shake and then go back to normal and keep alternating just like the main symptom.. Any ideas on what's happening?

    Something else I should mention, the T-Con main IC gets quite hot (not sure if It's normal.)

    Thanks in advance

      samsung ue46c6000 weird alternating lines
      by Mohammed Mecegguem
      Hello,

      I encountered an issue with my TV long before noticing a pattern of alternating red lines. Initially, I replaced the T-Con board, but the problem persisted. After a year, I decided to open the TV again and found some oil leaks around the CPU, RAMs, and LVDS FPC connector, likely from the thermal pads. I reconnected the LVDS connector but still faced the same issue with the alternating lines.

      At first, I thought the LVDS cable might be loose. I inspected the cable, found no damage, cleaned the connector, and reconnected it, but the issue remained. This led me to...

      APC BR1000G battery backup has a weird issue sometimes a bad battery icon and making a weird sound for about 30 seconds
      by sam_sam_sam
      This started a few days ago and does this about every 8 hours

      After it does this it goes back to normal no bad battery icon and no weird sounds and it goes to battery backup mode so I am not sure what is going on with this battery backup

      The battery backup is about 3 or 4 years old

      Dose anyone have any idea on how to troubleshoot this issue I have never had a battery backup do this kind-a thing before so I am not sure exactly how to troubleshoot it and where to start

      ASUS PRIME B550M-A AC weird behavior
      by RotVik
      Hello, I need a little help

      I got an ASUS PRIME B550M-A AC Motherboard, bad BIOS, it wont display or boot, unless I did CMOS Restart first, after that It will boot but if I modified the configuration of the bios and saved it ,again no image

      I got the BIOS .CAP file from ASUS official support, used a tool called ASUS CAP to BIN, and programmed it to the IC, soldered to the board and got it to boot correctly, all the way to Windows, but now the CPU fan stays at full speed all the time and if I try to power it off with power button it will restart instead, and there are...

      Weird behavior on 3.3V rail of a CORSAIR CX600
      by bimole
      Hi,

      A colleague gave me an apparently ill CORSAIR CX600.
      He told me that he heard a banging noise, and smelt the magic smoke.
      After tearing down the PSU, no burnt component, everything seems OK, but the PSU often refuses to stay ON. When shorting PS_ON to GND, the fan spins a bit a finally stops. No output voltages.

      I tried to treat some apparently bad solder joins and finally it seems to work OK... on the 12V and 5V rails!
      It's another story on the 3.3V rail...

      I have some devices to test deeply PSUs (scope, AC source, electronic load)...

      Lenovo Legion 5 high fan spin turns off after 34 seconds
      by twonk9098
      Hi all,

      I have a Lenovo Legion 5 with a Ryzen 7 series CPU and RTX 3070 GPU. My issue is that it turns on and all seems fine except after a few seconds the fans spin up high and the laptop turns off after 34 seconds.
      I can get into bios and can even boot and login to Windows however after 34 seconds no matter if Im at the bios screen or booted into Windows it will just turn off.

      I have managed to run HWmonitor and the temperatures of the CPU and GPU are fine, I can also touch the heatsync which is warm but not hot.

      I have tried a few new bios but exactly...
