so i just woke up, turned on my pc and 2 monitors, and 1 of them was fine, suddenly looked at the other and it was completely white with very vague 2-3 green lines. this monitor can also be used as a tv so i just disconnected the hdmi cable from the pc, tried turning it on again and this time its grey with vague white clouds that appear over time and some very small green pixels (i had to get close to see them), plugged it to the pc again and same grey screen issue, everything is plugged correctly, i just used it today and it was fine. it looks alot like this:
its a samsung T260HD and ive had it since like 2009
help and tips would be appreciated, thanks in advance.
