    Vertical bar stuck on TV Screen, AKAI AKTV434 UHD Smart

    Hi, I've got a weird case on a television. Backlight turns on and there is audio however screen slowly fades in with all different colours and weird vertical bars. I suspected the T-CON (Part number: HV430QUB-N4A) and so I went ahead and disconnected one side of the screen and left the other connected, after trying both ways the artifacts still seem to be there (in fact they got worse with one side disconnected). To me this indicated a T-CON problem not an LCD problem however after disconnecting both LCD ribbon cables from the T-CON only leaving the backlight connected is saw this (Image below). It seems as if a column of pixels got stuck partly open? Any ideas if this is fixable or what to do next. At this point I'm suspecting a bad T-CON and an LCD with a burnt-in column. I'd also like to mention that when the tv was fully assembled, this column would shine bright once the tv powers on (maybe bad T-CON caused this section to light up and previous owners left it on like this for a long time and it got burnt in? I don't think it's one of those two thin LCD boards as when I touch the ribbons on them I get no response.)

    There is a lot of reflection on the bottom left side of the image, please ignore that.

    Thanks in advance.

              Certainly bad Tcon, also your screen could be partially damaged but there's no way of knowing that without replacing the Tcon first.

                  Screen Display Vertical Multicolor Lines
                  by Stanley1843
                  Hello, I have a screen in where sometimes when I open it pop-up vertical multicolor lines (I would say the most of them are green). If I tun off and turn on the screen the lines dissapear or if I leave open the screen after approximately five minutes the lines gone. I measured the below voltages on the main PCB and on the T-CON board and the voltages are the same when it doesn’t display the vertical lines and when it displays the vertical lines. Also, I cleaned all the connectors very good with IPA. I moved back and forth the connectors and the COF tabs but the vertical lines didn't displayed...

                  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...

                  Lenovo Thinkpad E14 Gen3 stuck on "To interrupt normal startup, press Enter" screen
                  by BMCappelletti
                  Hi everyone.
                  Lenovo Thinkpad E14 Gen 3, stuck on the "To interrupt normal startup, press Enter" screen.
                  Found a lot of people with this issue, but with no definitive answer. Some people managed to get away accessing BIOS, going to Startup and turning off "Option Key Display". For me that only removed the interrupt normal start up message, leaving only the Lenovo logo.
                  Most people say hitting Enter does not work. It's true, if you wait a few seconds. But if you hit Enter right away you get the options to enter BIOS (which works), run diagnostics (goes to a...

                  MacBook A1990 vertical stripes on external screen
                  by ahoonid
                  Hey everyone,

                  I bought a MacBook A1990 with no screen. I bought it knowing the motherboard was defective but wasn't sure what the problem was until I received it. It actually turns on but as you see from the attachment, it has vertical stripes, on an external screen!!

                  The board is neat. Not opened before for sure. Just a little dust, nothing more.

                  Recovery using wifi can be opened, as can also be seen in the photo but it doesn't go all the way through after connecting it to a wifi. It downloads the initial Recovery files but never completes the rest of the...
