    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.
