    Grey/Gray Screen

    Hi, A friend of mine has a LG 47 inch 3d smart tv, their son kicked a ball and it hit the tv, The screen did not break but now all it shows is a gray/grey screen, Any ideas ?
    I spelled Grey 2 ways because some countries spell it different

      If the tv turns on and has backlight on but no picture usually means the screen has a short in half of the screen. You can test buy disconnectig one of the t con ribbons that go to the panel and turn it on half the screen should show a picture. Then swap them and disconnect the other side and see if you get a picture. If you don't get a picture each time on each side of the screen then the side you leave hooked up and no picture displays had a short in it.

                  Nah--Screen will be stuffed for certain! A spare-parts set now.....

                  The actual screen part is a sandwiched layer of glass with a plastic film that is only 1mm thick, and not supported very well--Even carrying roughly or a gentle knock with these newish sets can break them!

                  There doesnt always appear any visible damage on the face of the screen--even under strong light or backlight...

                          BTW, according to dictionaries both spellings of grey/gray are acceptable.

                              by Mad_Science
                              I have a older eddy current tester made by Olympus that uses interchangeable TFT-LCD screens. I have two devices that each take the same removable screens. One is an Olympus NORTEC 200D+ and the other is an Olympus SONIC 1200M EMI. I have searched the internet high and low for service manuals for these units with no luck. Both these units were used extensively by the US military for NDT on airplanes. The detachable screen plugs into the base unit via a weird non standard VGA connector. Buttons on the removable display are used to power the units on. When the power button is pressed the unit makes...

                              Macbook 2017 with touchbar (A1706) won't turn on after removing the screen

                              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...

                              Sanyo DP5834 - Gray Screen
                              by toddw65
                              Hey All,

                              I have a Sanyo DP5834 that did have an issue with the backlights, but I disassembled the unit and repaired the LED strips by resoldering all of the connectors. Now I've reassembled it and I have backlights and sound, but a grayish screen. I can tap on the screen and see that it's on, but no picture. All voltages seem to be correct on the power board.

                              Based on the LCD Flat panel TV troubleshooting guide by Bud Martin, I'm thinking the T-Con has failed because I'm getting 12v both into and out of FP1 on the T-Con. Am I on the right track?

                              Thanks,...

                              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...
