Cleaned the vents. The symptom is consistent with old age, heat or failing parts but I always like to try the usual generic reset (battery, AC out, hold power button for 60 seconds) but I'd like to know about maintenance over the years.
Did you crosspost?

Hi all
Today i was using my laptop (Acer Aspire 5742ZG) normally and then suddenly my screen freezes and turns off. The picture at that moment when the screen froze was covered with green horizontal lines and some small green squares and then the screen switched off while the laptop continued to operate normally.
I tried to restart my laptop, but the screen does not turn on, and looks like laptop is working normally because I can hear the windows login sound (led indicators for WIFI and HDD are working).
I tried to connect the laptop and TV via HDMI cable, but the TV does not get any picture.
Do you have any idea what could be the problem and how it might be solved?
I tried few solutions i found on other forums and youtube but nothing seems to work.
