    Sony kdl-46ex723 screen problem

    Hello Everyone!

    I thick white band has appeared on my KDL-46EX723 you can still see the picture behind it it's like a band of light, I'd post a picture if I know to lol, Really hoping the panel isn't dead/dying but I'm bracing myself for the bad news.

    Any help/advice would be truly appreciated.

      Does the bar move at all or is it completely stationary?

              Its possible the panel is faulty--or the tabs that connect it to the board.

              Also, the T-Con board could conceivably cause this sort of fault...

                  I've just changed the tabs around still the same problem, is there a way to test the T-Con without having to buy a replacement?

                      Sony KD-55XG9505 lines on screen problem
                      by Chrissygizmo
                      Hello again everyone,

                      This is my latest mission, to try getting this Sony tv back to normal working order…

                      I've only just got it today, when you power it up everything is as should be, in fact it works perfectly for a few minutes then the screen starts getting horizontal lines on & eventually the full screen goes back, I will upload photos of the problem & also some photos of the board etc. You might notice that I'm busy trying the tape method, I'm not sure exactly where the clock lines are so I'm just guessing & hoping for the best lol . I've already tried...

                      problem with replacing lcd screen
                      by mmccomputer
                      I have an HP model : 14-cf0011nf and I want to change its display screen (it has an original 14" full HD TN 30 pins panel) which works without problem but I want to put another screen with an IPS panel, the problem is that I tried several screens but there is no display except with the original screen, I never had this problem before I changed hundreds without problems but this PC is not 'accepted than its original screen
                      otherwise on the motherboard it displays edp and I don't know, do the panels I tried only work with the LVDS protocol?
                      If anyone has any information on the subject...

                      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...

                      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...

                      iphone XS turns off when press on screen.
                      by smic717394
                      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...
