Hello, the TV works, but for which time I do not want to start (most often after connecting any device under hdmi, but this is also not a rule, when watching netflix it can also spill) and its only sign of life is a flashing diode twice then break 3 sec and flashing again. Pulling out the plug doesn't help. The TV hangs up for some time, sometimes after an hour, and sometimes for a few days. The situation appears very often. What could be the reason? TV no longer guaranteed, sent to a local service, where they can't diagnose what happened. They mentioned something, PLN 300 paid and the TV still freaks out. Please help
