I recently got a Hanns G HG281DPB 27'' monitor from a friend of mine since he was going to throw it away since he got a new 3D monitor and after fixing a button issue i ran into an issue i can't seem to put my finger on. Randomly and at times far between failures the display just fails completely. Im running 2 other monitors so i know its not a graphics issue since the other monitors function properly. The power light is still on but the display is completely black and will not come back on. A few hours later after having it off I can turn it back on and use it. At first i thought it was an overheating issue but it will fail the first time i turn it on every once and a while and its not even remotely warm. Any ideas?
