    LG 55EG910v (Green Nosie Screen) BURNT on NOT ?

    Hi ! to all fellows out there!

    I have an LG 55inch 55RG910V-ZB Curved TV. With the following problem: When I turn it ON with Remote I get a Green noise Screen (attached foto).
    I have tried reseating all ribons, Checked PSU 24V,12V,3v ,etc voltages.

    The TV opens on the first Green noise screen and it freezes there -no respone of menu keys ,etc -only on/off via Remote. (I also noticed carefully that except from green noise screen there is a ghost image at bottom and left vertical side)
    I tried connected the lan and I can seee TV via local lan (as a device I didn't tried to cast etc).

    Is there any way of testinf T-con? I read different posts that I can check T-con to view with Red,Green,Blue screen.

    LG technicians and service manual estimates this is a panel fault (burnt screen!) BUT I am far for beliving it yet! as 2 days ago (of the total 10days TV not working) ONLY ONCE! TV started OK with normal screen menus, broadcast channels etc ! 😁

    Please any help what to try would be welcome!

    Thank you for your time.

      Panel issue at side COF of the right side ( need to remove all.. if the set belong to you..you can play with it by cutting the right bezel and remove the COF... but if it will display correct image are unknown.. such TV described as scrap.

              What do you mean? With a PC? You see the TV received by TV set? With which program?

              My guess is it could be a bad tcon.. put that in freezer and then when frost mount it and test tv..

                  Yes I wasn't clear enough: I mean if I connect the LAN the TV can be detected on the lan vua the ip address.

                              No luck So far . I really don't know how to proceed. Only one time TV started normally without any issues. Despite that 15 days now it show signs of burnt screen!. Is there any chance of having problems with T-con? May be I try Diah recommendation and start dremel(ling) screen apart!

                                  Well if you can get a tcon at reasonable price, try one, if no joy probably time to give up.

                                      Where are and how are those burnings? Dremeling is not an answer because you don't know where are, if there are, the faulty COG, or if there are COF, you don't even know on which side are those..

                                          As funny as it would be to see someone take a dremel to a tv, I don't think that's what Diah meant for you to do.

                                              LCD TV Green/Pink screen problem
                                              by jimjoe123
                                              I have a Dick Smith 37" LCD TV, Model GE6804. I am using it as PC extended monitor only.

                                              Problem is while watching tv, I hear a semi loud click(like a electrical breaker tripping due to overload, just sound like it but no actual electrical overload), then screen is covered with green or pink. I can still see the original picture image but overlayed by green or pink. See attached images. Pink.jpg is what I see, and Normal.jpg is before green or pink screen, What I captured was pink screen, but about 80% of time it's green and 20% of time it's pink.

                                              Then each time...

                                              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...

                                              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...
