1- Broken screenAlthough it is the most common and non-repairable panel malfunction, our customers persistently (yes, persistently) believe that it can be repaired by saying "the screen is only intact windshield is gone" or "there is a little line on the screen, just nothing else". Dear visitor; This malfunction cannot be repaired anywhere in the world. Do not mind those who say "There is a master, he can fix it".
2- AND............. Dead pixels.................
These black spot (s), which are usually noticed on a white background, unfortunately cannot be repaired. Dust dirt etc. left behind the panel with dead pixels. It is difficult to separate things from each other, so if your TV was recently repaired and you noticed it after repair, let the repairman know maybe it is dust.
3- Polarizer film tear
If the film covering the panel is damaged, there will be no image in that area of the screen, only bright light will leak. You can tell the difference between dead pixels by touching.
