Question Monitor screen goes black when ever i change resolution

[Gylon]

Hello, so basically whenever i change resolution/open a fullscreen game/or change source from HDMI to Analog and back to HDMI my samsung syncmaster SA550 monitor display turns black and the on/off red light start blinking. To fix that i need to turn it off for 5mins and restart my computer, i already tested my pc with another monitor and it’s working fine. What’s the problem with my monitor ?

test with another monitor? could be your gpu.
full system spec? include make and model of the psu

well, i tested it with another monitor as i said and it’s working it’s not the gpu or psu, i changed the resolution and played full screen games... btw i just opened it and the circuit is extremely hot i think that’s the problem
