    Hyundai U90d no screen flash at all

    The Green Power light will come on and then go to amber. The screen never flashes on at all. Supposedly this monitor was used for about 3 weeks. and then sat on a shelf for months. IT was made in may 07.

    There is a burned up ic on the bottom of the board and i have no clue how to figure out what it was, or what would have caused it to go bad.

    FYI: the 12v on the inverter is steady at 11.97v and the 5v is steady at 5.05v There is no 3.3v on this board that i can find.

    Any Ideas guys?

          I agree. The burned up (left) is mirrored on the right. See what part number is that and you will know the part no. for the burned up.

                          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...

                          Hi,

                          I have a iphone XS that came in for a screen replacement, the screen was badly cracked, and inside missing scues, on the back of the screen still the blue protector, the screen was a LCD. So we replaced the screen and all good, installed the screen and we noticed that pressing the screen with a bit of force but not excessive, the phone dies. After plugging the charger it turns back on, but again if you press it it dies. I open the phone again, and I can't see anything major, with the phone open, if I press on the logic board, battery, charging board, or even putting pressure on...

                          Nikon D800 camera - flash don’t work and capacitor don’t charge
                          by corrize
                          Hello, I'm stuck in troubleshooting…
                          The flash system works like that : when the (mechanic) flash button is pressed, the flash mecanically pop up, and a circuit buck boost elevate 7v (batt) to 200-300v (?) for charging the big capacitor. And when the photo shoot button is pressed, the capacitor is discharged in the xeon light.

                          In the D800, there is a first « power board » close to the battery. 2 wires (batt 7v) goes to another little « flash board ». I measured 7v, so ok.
                          When I press the flash button, it's detected by the system, flash icon appear on LDC display....

                          Samsung UE55JU6800K half screen dark
                          by Chrissygizmo
                          Hello everyone, I’ve just been given a Samsung UE55JU6800K smart tv as it had white spots on the screen due to the led lenses falling off. After refitting them & putting the tv back together I thought it was a nice easy fix for a free bedroom tv , then I tried it before screwing the back into place. I realised that the right side of the screen was darker than the other side, I removed the screen again as I thought the backlights had failed but they are fine.
                          I put the screen back in place & turned it back on . The screen seemed to be ok again but different screens on the same...
