Hi. 1: plug out power connector, mains power, and leave TV with no power for a full night. Sometimes, RAM or EEPROM needs resetting. 2: Remote has battery? Hope this helps, if not it its the powersupply or mainboard of the TV. Best
Hi Jacob. Bad capacitors could very well be the problem. Probably the most common issue with TV's, and not just Samsung. (They just had the biggest shitstorm) Also LG, Sony and so on. I would go for this, as a first attempt of trying to fix the issue. If you know your way around the basic electronics, you should go look for bad capacitors, most likely on the PSU board. Remember to check the ESR (internal resistance) of the capacitor, not just the value i Farads. Best Anders
