Question about HP Pavilion a1720n PC Desktop
Welcome to Fixya
No signal usually tells you that the video cable is not properly plug in at the back of the computer or the video card has gone bad. If your computer has a built video card, you can use that one to test the PCI video card if its malfunctioning. You might need to take out the PCI video card inorder fro you to use the onboard video card.
