Get no video detected when pic is turned on
Is this a good question?
Repair guides and troubleshooting for the HP Compaq DC7500, a business class desktop computer introduced in 2007.
This can be caused by a couple reasons. First When you turn on the PC, does it make any particular noise? If the PC is turning on normal I would try switching your display wire in order to make sure that its not simply the wire not sending the image to your monitor. If after you switch the wire you still don’t see an image try to to double check that your monitor is actually able to display an image., by turning the monitor off and than back on. If your able to see the start up screen of your monitor, than you might need to trouble shoot the display card in your desktop. First try this and than let me know if you still need more help.
