    I assume you've done the "obvious" and reset all picture settings to defaults?

      Re: gray screen

      i have done the reset to factory settings. just a few minutes ago it went to norm for about 1 second and back to the white and grayish screen again. tried to take a picture of it but didnt show right. the best way to describe it is like their is a white or gray cloud covering the picture. it goes to norm for a couple of seconds and the cloud comes back

        Re: gray screen

        We have seen this before and it turned out to be the T-con board, which is usually less than $30 to replace. That would be my suggestion.
        37LG10 is an LCD display. LG does not make any 37" plasmas, anyway.

            First, you would need to open up your TV and locate the part number written on the board.
            If you post a picture of the inside of your TV we can locate the T-con for you.

                Any pictures of the T-CON board, it can be as simple as blown surface mounted fuse on the T-CON board.

                    Re: gray screen

                    You can see WHITE surface mounted fuse on the left side of the bottom connector. You need to check (with the TV on) to see what DC voltage you have on both ends of the fuse, black probe of the DC voltmeter will be at the metal chassis, the red probe will be testing each end of the fuse for DC voltage, report what you find. Meter should be set to 20V scale.

                      Re: gray screen

                      quick question; can anyone tell me where the inverter board(s) are located on the lg model 37lg10-um? And also, how do remove the metal casing off of the t-con board from same model.

                        The inverter boards will quite likely be on either side of the TV. There may only be one board.

                        The inverter is not the fault in this case as the inverter is only responsible for backlighting the display. Since the display is well lit it is not the fault.

                          I have same problem. Voltage showing 12.65 on top of fuse and 12.88 on bottom. Any suggestions?

                            Usually AS15F IC on t-con board.

                              Not sure what that means. Best to get a new T-con board? Only ones I find are used boards on e-bay pulled from "working TVs."

                                  If you can solder a chip on the board with 0.5mm pitch between leads, then replace the AS15F, otherwise, replace the board. The boards are pulls from TVs with cracked screens so receiving a dud is a possibility.

                                      Hi Guys, new here.....
                                      I have one of the LG 37LG10 LCD TV's with the white screen or white clouding syndrome. Rumor has it from the above thread that either the T-Conn board or the AF15U or equivalent will do the job. Has anyone successfully fixed the syndrome by replacing the card or chip? If so where can one get (1) chip, searching comes up with vendors that will sell you numerous batches but nary a one that will sell just 1. I realize I can go with the card but I am good at soldering, even the small packages. Help is appreciated..... Regards; JOE

                                          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...

                                          I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.

                                          I ordered a supposedly ‘new' Tcon board this time, and

                                          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...

                                          Samsung UN50NU7400 - No Picture (but boot screen and screensaver)
                                          by arbitarytwist
                                          Have a Samsung UN50NU7400 which shows a boot screen and a screen saver if left on long enough but no picture ?

                                          Would a moving screen saver confirm that the panel is ok or it could still be a panel issue ?

                                          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...
