    Sony KDL37M3000 sparkly

    Sony KDL37M3000 sparkly in picture. I have not run into this one before so not sure but I think the screen maybe bad or?? I have had to turn the brighness all the way up and also the backlight yet the picture still looks dark and too red and around some dark areas it's like blue or green sparkly. Ideas?

          OK, can you tell me where to tap off of for it? Or I see like 22 different little points that all say gama something.

                  Bad gamma chip, replace AS15 to fix.

                          Yes but often very expensive due to high failure rate.

                              Can't find the correct board or a repair kit. Even emailed SJ and nada.

                                  I am pretty sure you can use any as-15 chip, atleast I remember reading it here or some other place.

                                          Can you not read the markings on the chip at all? Sometimes I have to take a digital macro photo and adjust the light via iPhone photo editor to read em.

                                                  I have bought several as-15 chips from this seller and had a 100% success rate with their chips.

The lines sometimes get bigger/smaller vertically and bounce back. See the video for the problem. It seems to be happening after it warms up after an hour or so. Happens regardless of source. Right now there's nothing but power cable connected and it's happening. We did hook up a new Nintendo Switch to our HDMI switching receiver today, and played for a while with no issues, but this problem didn't occur til a few hours later while...

                                                                      i want to repair a Sony KD-75XF9005 TV that initially only showed a grey picture.
                                                                      Backlight seems to work, Sound (Setup menu after reset) works.
                                                                      If i dissconnect the left FFC cable from TCON to panel i have half a screen on the right. If left cable is connected always only the grey screen.
                                                                      Interchanged the cables, its always only the right side that is working. Always grey if left side is connected.
                                                                      With my small knowledge i would think at least the cables are good.

                                                                      Can this happen because of a bad tcon board?
                                                                      Or is it always a bad/shorted...

                                                                      So a few months ago my Sony XBR 49x900e TV screen stopped displaying the picture but the backlight comes on and I still get sound when I use the remote and navigate to certain apps. I haven't checked anything with the meter yet but started with ordering some replacement boards. I've tried replacing the BMKS board (used from ebay) and also completed the firmware upgrade based on Nicks TV repairs youtube video. I've also replaced the TCON (twice) and PIB.

                                                                      All of these changes have resulted in the same issue with no picture. I've also tried disconnecting the ribbons...
