Whenever I boot up my computer the screen will turn on for a second, then go black, but the power light stays on. While it goes through the BIOS screens, Window screens, etc...it will keep flashing on every time it reaches a new screen, but instantly goes black again. It also makes a very slight beeping sound coming from the back of it. I tried shining a flashlight to see a dull image, but I don't see anything. What could this be, and is it worth replacing or just buying a new monitor? Thanks!

Have you tried another Monitor ??
I saw something similar to this when the power supply for the Florescent backlight in the monitor went bad.

Yes, I plugged in another monitor and it works just fine, so its definitely the monitor that's the issue. I'm just not sure if its the backlight, inverter, or something else. I've never heard a monitor make the low beeping sound that it's making from the back. You can barely hear it.

Check to see if it's still in warranty ... Mine were.
I've had to send 3 monitors back for warranty because of the short life of Florescent backlights ... Or supply issues
My next monitors will be LED backlit

I got it from a friend who is wanting me to look at it. I don't think its under warranty, but I'll ask. I've taken apart a few laptop LCD's, but never replaced any of the parts. If it isn't worth the time or money to replace, then I'll just recommend him buy a new monitor. Thank you. :p
