Question about HP Compaq Presario F730US Notebook
When I turn on my Compaq Presario F700 laptop, the screen is black and stays that way. At certain angles, there is limited ability to see things on the screen. I've tried the "fn" f8 button, which has no effect on this problem. Is there anything else I can do?
its comes on but blank black screen and its only a year old warranty just ran out
If you can still see a faint image on the screen, then its the inverter coil or the inverter itself which has gone bad or maybe even worked itself loose causing a bad connection.
Either way you will have to take it to PC repair shop to be looked at.
Good luck and thanks for using Fixya!

Sometimes there is a switch up above the keyboard that can get stuck down. The switch controls the backlight on the LCD, so if it gets stuck down you'll have this dimming problem.
If the switch isn't stuck, or if it isn't visible you might have a bad LCD inverter. It's a very common problem. The inverters are $10-$20(USD) on eBay. They are moderately difficult to install, but not impossible.
Please let me know if you have any other questions. I'll monitor this thread.
