Hi everyone,
I just bought a monster 75" Samsung UN75MU6300 with the hope of fixing problems with the screen. I initially thought it was just a backlight issue, as the picture darkens gradually from right to left (meaning that the far left side is super dark, and far right side is seemingly normal). Once I got it home, however, I ran some screen tests and see that there are possibly more issues.
There seems to be a timing issue on the left side, as there are weird artifacts and transitions from one color to another leave horizontal streaks that take a few seconds to fade away. Once they catch up, the left side seems to produce the colors normally, at least to my novice eye. While there does appear to be a backlight problem in the center of the screen, it seems to be a fairly minor problem, at least relative to what I initially thought. I now suspect either the T-con board, bad connectors or cables or a completely smoked panel.
I posted a video of the full screen test here: https://youtu.be/FpPzSDXP3LY
I also attached a few screenshots to this post
I would greatly appreciate any insights you guys may be able to offer, as this is actually my first TV repair project. I'll catch up pretty quickly, I hope. Worst case scenario, I wasted $80 for the experience.
Thanks in advance,
SDG
