My monitor will turn on and i can browse through but as soon as i get to the right screen it will show the the picture for a second or two then just go black, the sound still comes through and the monitor is still on but the screen is black?

I'm afraid this looks like an electronic fault. Some component, most likely a capacitor, has degraded, is overheating and going out of spec.
You just might be able to squeeze some more hours of work - but the monitor is still likely to drop dead any moment now - by rigging a computer fan on the backside to extract hot air from the inside.
Possibly, the problem might have a noise factor - try adding a ferrite shielding on the cable (unless one is already there, as it often is) and see whether the thirty minutes' grace period extend somewhat.
A probably unsatisfactory solution might be to drive it at a lower resolution, so that the more relaxed frequency constraints do not stress the component so much.
When the capacitor finally blows, you might be able to recognize it and have it replaced; it's likely a US $1 component and is probably in the LCD driver section. Perhaps, just perhaps, you could already be able to see it with the naked eye looking for a component that looks "wrong" - a small cylinder that looks bloated, with electrolyte leaking, whitish powder around the base, etc. But you would still need some solder work to get it replaced - and, if it's a SMD component, chances are it can't be done at home.
Sorry for the bad news...

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

The backlights inverter circuits are not working, it can be due to bad DC power supply feeding it, or failing inverter circuits. I would inspect the power supply section first to see if it has any bad caps with bulging/leaking tops first.

If you are going to DIY and already try the monitor with another PC, and have proper tools and know safety precaution then please read on:

Or www.digikey.com just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.
SOURCE: Hi Support I hope you can
From your description of the problem, I would suggest that the issue is not with the inputs, but with an internal fault. The fact it powers up then cuts off is symptomatic of power capacitors failing, or could be due to a faulty circuit component on the internal board. For reasons of safety, I'd strongly suggest that you take this to a qualified engineer for more accurate analysis and repair, rather than attempting to trace the fault yourself. Check also the main power lead and socket on the monitor and substitute it for a new one to test it.
I'm also assuming you tried this monitor on another computer? A failing graphics card or chip would also give you the problem you describe

There is a good chance the power supply board has one or two capacitors that are open,"they often bulge at the top" making it easier to spot, replacement of parts only option.
