With noticed today that the screen of my tv is very dark. Have brightness and so synonymous already set to bright but still quite dark. What can this be? Have read the HDMI cable may be broken but I look over Netflix therefore falls away schonmal
Do not look at brightness in the classic settings for brightness and contradt, but at the backlight. If that does not help, and you still have an older one with Kaltkathodeb tubes, these are used up. If you can't change that yourself (which means a complete disassembly of the screen, and then manages to get matching replacement tubes, the repair is so expensive that it's not worth it anymore.) The problem is that they glow with almost maximum power during the entire operating time Brightness.
Often it is the automatic brightness control. Turn this off, because it looks how bright the environment is and regulates the display accordingly.
Well, if it is dark then it seems quite bright but if it is bright outside it is just quite dark
