    Blue screen on a TV - Telefunken d49u400x4cwi

    Hey, I have a problem with my TV, it's showing nothing but a blueish "image" if I can call it that, no matter what I do.


    Tried switching the hdmi port, pressing the buttons on the back of the TV does nothing and I don't know what's wrong with it.

    When plugging it in to the wall socket, the tiny status LED blinks normally a couple of times, it responds to the on / off button on the remote, but nothing else.

    What should I do or how should I test it further to figure out what's wrong with it ?

    Brand and model number : Telefunken d49u400x4cwi


    What I have managed to find so far is that the motherboard is called Vestel 17MB120 along with it's power source that's also Vestel 17IPS72 as for the t-con board , I guess it's a LG display since that's what's written on the board.







    From what I understand, one can reflash the motherboard using a USB stick and firmware files and for that I've found these :





    Could you guide me as to what to do, which files to go for to attempt a reflash and see if that's the issue ?

      Thank you! I appreciate it. Do you have any tutorial or instructions anywhere on how to properly do it so I don't damage it further?

      I know that the usb stick must be formatted as FAT32 and placing the files directly on to the stick, without any folders, does that mean taking each file from the zip you just posted and placing it directly on the main usb stick folder?

          Macbook 2017 with touchbar (A1706) won't turn on after removing the screen
          by Ryan.man
          Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!

          My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.

          This time the original cable broke too close to the screen, it can't be fixed without tearing the screen...

          Macbook Air M2 A2681 Kernel panics after screen replacement
          by reformatt
          Just had a customer bring in a M2 MBA A2681 that had had a screen replacement in April at another repairer. Since then, she has been getting intermittent kernel panics. It's an aftermarket screen, and of course it fails in diagnostics as the calibration hasn't been done. The error in the panic log is "No device added after powering on the rails".

          It seems the original repairer has swapped the board and the screen to other MAC's, and said that it isn't a screen issue. From what I understand, by doing a quick search on Google, this is in fact a screen issue. The panic relates...

          Samsung 65" UE65TU7000KXXU VER:02/UTU7000 TV Blue screen
          by gbbradshaw
          Hi.
          I have the Samsung TV Model: UE65TU7000KXXU VER:02/UTU7000 which has developed the following issue: blue screen while the sound it's still working. This happened after the screen developed some horizontal lines at first and then the next day suddenly turned into blue background. the screen was not damaged or anything. I can't access the menu. I have taken the tv to a local tech to have a look and he said that he thinks that it might be the pcb board as the back-lights are working and the sound aswell . I was hoping maybe you can guide me if I should buy the pcb board or not? Thanks

          Dell XPS Plus 9320 blue screen and rebooting
          by siuras676
          Hi everyone,
          I have a Dell XPS 9320 in for repair, and the machine has a strange issue.

          First, a bit of history: the laptop came in after liquid damage and was completely dead. I've repaired all the broken traces, replaced the damaged components, and it now powers on.

          However, it's now showing a Windows blue screen related to hardware (as seen in the picture), along with another Dell error I've never seen before.

          Has anyone encountered this issue on a Dell machine before and could point me in the right direction? I've checked the power rails around...
