    Re: Vizio P50hdtv10a vertical bar

    Weird things going on with this set, Im thinking my new upper ydrv is bad also. I finally got something to come up on the screen. The only way I could do that though was by unplugging the P3 connector from the y sustain, leaving the buffers attached at the pads. As soon as I hook p3 back up I get nothing on screen,no prime. Picture is with P3 plug disconnected.

        Yeah I would recheck those FETs on the Y buffers again.

                Open circuit except one way there will be a diode drop around 400 to 800mV.

                    Its not the buffer boards that are bad, had a good set installed, does same thing. White plug connected to y sus, I get nothing. Disconnect that plug I get a full distorted white screen. I cannot even get the vertical bar on screen anymore that I started this post with.

                        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...

                        Samsung LC32HG70QQUXEN - vertical and horizontal stripes across the screen
                        by kotel studios
                        Hi,

                        Just now my Samsung LC32HG70QQUXEN monitor gave up on me. On cold boots I get many vertical stripes going across the screen (see the attached picture). After it runs for 1-2 minutes those go away but there are horizontal stripes going across the whole screen no matter of the input and PCs I use. (couldn't take an picture of it since the image size goes to 20MB and the camera doesn't pick them up)

                        In a video about a 27" monitor with an similar issue the guy removes one resistor and supposedly the entire monitor goes back to life? For sure this fix is only temporary....

                        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...

                        To fix laptop screen vertical line by working on its EDP cable
                        by almarhum
                        Has one here really gone through fixing laptop screen vertical line(s) by repairing/replacing its Embedded DisplayPort (EDP) cable, so would recount and share the complete steps of the process here now?

                        As most, if not all, believe the laptop screen vertical line(s) caused by defective Embedded DisplayPort (EDP) cable which slipped and passed through either laptop screen hinge but post here is asking help to elaborate definitively the useful, real knowledge of repairing in the most complete, correct way, esp. can decide/determine whether the cable can still be fixed or must be re...
