Response from Jonathan: Scott,

Sounds like your monitor is getting power so the problem is probably not your monitor. We typically use the term playing blind for games where we can hear the game’s sound coming from the speakers but do not have anything on the screen. If this is the case with yours, we recommend checking the wiring and connectors between your main board and your monitor chassis. If you don’t have sound coming from the game, you might need to check your power supply and main board to see if it is getting the correct voltage.

When you are getting these kind of symptoms, it’s always a good idea to get your multimeter out and start checking voltages. Check out our post on Checking And Replacing A Power Supply for more information. Hope that helps. Thank you for your question and good luck with your repair.
