hi, I got problem with my sony 17" (SDM-SH73)LCD monitor that I got around Thanks Giving last year. While i was playing videogame, the screen went blank and when i tried to turn it back on, it'd come back for a split second and go blank and again. Anybody knows what's going on? I tried to unplug it, turned it back on, read the manual, but nothing changes. I don't know what cause this, and I probably cannot afford the one like it ever again. Is there anything i can do? Thank you for your help..
