HP Pavilion DV2615nr LCD intermittently flickers and sometimes goes black-what do I replace first?

I have an HP DV2615nr laptop that is about 2 yrs old. Over the last 3-4 months the LCD will flicker or go black at times. If I open and close the lid several times and get it open to 'just the right spot', it will come on and stay on...sometimes it just flickers constantly....sometimes it stays black. I am trying to determine if it is the backlight, the inverter or the LCD? Any ideas on trouble shooting this before I purchase parts? After querying this on the web, it does seem to be a standard problem on HP Pavilion laptops :( Thanks in advance for your help!?

There is one or several flat ribbon cables that go from the mother board thru the hinges to the screen. One or more of those cables are no making contact all of the time. They have a tendency to work their way out of the connector. What should be done is to remove the back carefully and find all of the ribbons and reseat each one of them. that will probably clear up the problem. I have a laptop that I have to do the proceedure to about once a year.

Thank you Re-design! That was exactly it :) I removed the cover for the screen, found that there was one large flat cable up the back that was not connected completely. A quick reconnect, a piece of tape, and voila! Thanks again for taking the time to help...
