        i tested the power supply and i think it's ok. I put a 12v bulb on the 12v line and resistor between inv-on and 3.3v line and put the light connectors from backlight in Psu. The light bulb is lit and 12v is 12v . I put the connectors from backlight in and backlight is turning on without flickering.

        also there is 391v on the big cap so PFC is working? so i think the mainboard has a problem?
        the inv-on voltage is stable. I soldered a new tuner in before maybe i did something wrong or damaged something. can`t see anything wrong

            has the flickering only just started after you fitted a new tuner or was it there before fitting?

                    Lenovo Thinkpad X1 Gen 10 - Flickering Screen
                    by Ado02
                    Hello everyone,

                    We recently replaced the OLED screen on a Lenovo ThinkPad X1 Gen 10. After about a month, the replacement screen began to flicker. Initially, updating the Intel® Iris® Xe graphics driver resolved the issue for about a week. However, when the problem recurred, updating the driver again had no effect.

                    The flickering only occurs once the system reaches the Windows login screen. Interestingly, if we disable the Intel GPU driver or connect the laptop to an external monitor, the flickering stops. We have tried installing two different replacement screens,...

                    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...

                    LG 55UH6150- trouble powering up, then half lit screen (pictures!)
                    by valvashon
                    The 55" LG has been in the basement for a few months without being used. Turned it on yesterday, set came on as it should and showed a complete screen for about 5 seconds (was on a broadcast channel but no antenna was connected), then the screen went mostly dark with about 1/3 of the screen on the right lighting up with brighter lines in that lit part (sorry, no pictures of that). Power LED was cycling too, preventing the TV from fully powering up.
                    Pulled the back off, all boards looked OK. Pulled the LED connector, turned the set on to see if it would power up but I don't belive it...

                    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...
