Hello,I would really appreciate help with this issue: My 2 yrs.old Sony pc "pvc 2252" (Vaio ,Motherboard P4SD VL)will not display anything.When monitor is turned on, a small screen flashes for few seconds ''No signal input'' then back to black.Connected monitor to other pc and it works fine. removed video card placed it in other pc ,working as well . I checked all connections and pins ...I have no clue to whats going on. I don't see any other blue video connector ,but video card does have a white slightly larger connector just next to monitor connector,but I don't know what its for. Please if anyone responds keep in mind that my knowledge of pc is elementary. Thank you.Pat
