Question about HP Vs17 17" LCD Flat Panel Monitor
Our screen comes on fine and then goes dark every time after about 2 seconds
Sounds like classic symptoms of capacitor failure.
Old thread, but in case anyone else is still looking for an answer, the problem is probably bad capacitors on the power board. There was a world-wide problem with capacitors in the early 2000's that affected all kinds of electronics. For a good summary/review see https://en.wikipedia.org/wiki/Capacitor_plague .
Make sure the replacement capacitors are the proper size, specs (volts (v) & micro-farads (mf)) and temperature rated for 105°C. Make sure to install them in the proper orientation, they have a positive (+) and negative (-) terminal. I had 3 bad ones but replaced them all. It's actually quite simple and cheap if you have basic soldering skills. If you're not sure, research soldering technique and safety. Be Safe Out There.

If this happens before you turn your computer on, then your monitor is automatically saving power. Just turn your computer (the big box) on before the monitor, and it'll be fine.
If this happens after you turn your computer on, you have a power problem. You can either get it fixed, or my recommendation would be getting it replaced.
