I have 2 LG Flatron m2262D monitors which I use for my gaming setup and console. I know that these monitor-TVs are unreliable and not really good quality but as I was doing my rendering and basic stuff, one of the monitors went off and when I tried to open it , It displayed V3.14.0 in front of a White scene and no buttons or the remote key didnt work.I plugged out HDMI and left power cord in because I tought maybe it was updating and shutting off power might end up in no firmware or smt  like that. 2 hours later it was the still same and I started thinking it might have overheated as their cooling efficency is terrible, put it in front of the cooler and after 1-2 hours later came bacl plugged power and pretty much nothing changed. I searched everywhere and nobody had a problem like this so I wanted to ask you guys...
