    Toshiba L50-B-1U8 no image before windows

    Hi!

    I have a Toshiba L50-B-1U8 that while booting it show no image. The screen turns on though.

    During this phase if I press F2 it doesn't come out of the booting process and I have to turn it off in the power button. I'm assuming it enter the bios menu, it just doesn't shows it on the screen.

    After the booting phase it starts loading windows and the image shows up normally after that. In windows everything is normal and every hardware component works fine.

    The problem is only during the booting process before loading windows.

    It was using bios version 2.0 but I downgraded it to the version 1.9 to see if it solved the problem. It didn't, still the same behavior. I've got the bios from here.

    More info about the laptop:

    Disconnect the hard drive and see if it enters bios screen.

          Disconnect internal LCD
          Connect via HDMI and see difference.

            No image during boot with an external monitor via HDMI
            With and without internal LCD connected, tried both ways

              DRIVER_PNP_WATCHDOG error re. old drivers in Windows 11 install image
              by japlytic
              In a Beelink GTR mini PC, mine has an Intel AX200NGW WLAN module.

              Tried (only with keyboard/mouse connected):
              • BIOS + database update
              • Using latest Windows 11 image built with official image creation tool
              • Previous setup version for Windows 11 installer
              • Replacing SSD without a slow block (the previous SSD had a slow block with access time > 500 mS)
              • TPM reset (worked to the point where DRIVER_PNP_WATCHDOG error message is displayed briefly after the point of stalling)
              • Disabling power to WLAN and LAN modules in BIOS (Advanced > AMD PBS > PCI Express Configuration)
              ...

              by dfear
              I need your help with a Toshiba 50" QLED (Vestel made) TV.

              The TV is: toshiba 50QF5D53DB 2402.
              Additional details:
              Screen: VES500QNZB-P5-Z71

              T-con: STCON495GS01U35392321349

              The TV has the following fault:
              Powers on, no image or sound, but DOES have backlight

              I have performed the following testing:

              1) I have disconnected each of the t-con to gate driver flexes in turn. No image appeared on the screen after each flex was disconnected.

              2) T-CON testing:

              So i have 2 laptops, both had no image, all voltages are present except for igpu that comes after intel xe drivers installation i flash bios, one of 2 worked but had slow boot, that probably has something to do with management engine, also boot guard is active level 4
              on all bios i tried, i attach both original bios, and also the one i flash and worked with slow boot
              can someone clean any of them so i can try them
              thank you
              i tried to do it myself but none of them works

              Sony KD-75XG8096 no image
              by raydem
              Hello,

              I have a Sony KD-75XG8096 that has backlight and sound, but no picture.

              I went straight to the T-CON board (18Y_SNTH2TA6AV0.1) and checked the following:

              VIN = 12 V
              Fuse is OK
              1.5 V, 1.8 V, 2.5 V, and 3.3 V rails are present and correct
              There are no VSS1, HAVDD, AVDD1, or HVIN_12 voltages
              I have not found any short circuits. I also used rosin to help detect any possible hotspots, but nothing was found.

              The HVIN_12 voltage is controlled by a MOSFET through an RT6948. The MOSFET tests good, and the RT6948 output to...
