    BLACK SQUARE on top left screen Pioneer pro-1410HD plasma TV

    I tried to fix the vertical white bar on the right side of the screen.I reseated the ribbon cables but the white bar was still there. Thanks to the forum I was told it was not repairable. NOW a new problem. After about 100 screws, I put it back together. Now There is a black square on the top left side. I tried to reseat the ribbon cables but that did not work. Any suggestions?

          Unfortunately it does look like the panel driver for that part of the panel has failed - it is worth checking you seated the Vadr power connector though.
          Be careful not to reseat all connectors with power on or shortly after as this can cause further damage.
          The ribbons are also very thin... it's possible that you tore one of them.

                  Two small wires on a 3-pin header, connects between the boards running across top & bottom and the Y-drive/X-drive boards. Approx 75V-80V on that connector.

                          How did you remove the ribbons? I thought they were bonded on this set. Maybe I'm thinking of another panel... the Kuro 9G ones are... and so are the 8G ones...

                              they were just clipped in with a plastic locking bar

                                  Yea... I am thinking of another set.
                                  You're just seeing the difference between priming glow and no priming glow.
                                  The drivers running along the top and bottom edges of the screen put the actual picture information on the panel.
                                  The drivers running along the side (X/Y-drive plus Y-buffer) are responsible for creating the priming glow and making the actual display image appear.
                                  (Modern plasma panels make very low priming glow to improve image quality.)

                                      do you think a new y upper buffer will fix this? also I was taking the upper buffer out and I guess I was still plugged in and it sparked and the tv turned off. Now when I try to turn it on it turns on for 1 second then clicks and turns off. Is there a master reset?

                                          Probably toasted the panel completely now!

                                              No as I said this will never be fixed by a y-buffer
                                              The panel is bad , you may have caused additional damage but it was bad to start with unfortunately and there's nothing you can do. Sorry!

                                                  Panasonic Plasma screen interference on left half of screen
                                                  by Zelek11
                                                  My Panasonic Plasma model P55VT50 has started displaying "interference" on just the left half of the screen only (left when facing the screen). Sometimes it's concentrated in about the first 30 seconds after startup, then disappears. Other times it's fine at startup and then randomly does it later on. When it flashes the interference it's very quick and doesn't stay on the screen unless it flashes repeatedly in a row.



                                                  This image is a screen shot from a video I took. This is an example of the interference at its worst. Often the interference is much smaller...

                                                  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...

                                                  Hi,

                                                  Trying to work out if this is TFT problem or TCon issue.
                                                  The TV powers up but the top half of the screen, from the right it is OK, but as you look across to the left halfway across it starts get duller and duller until it is very dark on the lefthand side, currently I trying to clean the remote as it seems to have something film wise on the pads stopping it from registering buttons pressed.

                                                  Also when changing the screen size of Windows PC display to say to a smaller pixel sizewindow, the original window displayin the top left stays/takes a few seconds to disappear?...

                                                  Hello,

                                                  Stopped by this site trying to fix my parents Panasonic Plasma TV.

                                                  Model number is TH-50PZ85U

                                                  Power comes on and the red power light stays on solid.

                                                  Did a few checks like hold the power button on for 60 seconds, hold the - Volume while holding the menu button, no luck, still@ blank grey screen as the screen lights up very vague.

                                                  I also hear a few clicks.

                                                  I also think my parents said there was a thunderstorm and the TV failed after that.

                                                  Section 6 in the service manual talks about power and no screen,...

                                                  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...
