Having problems with your HP Pavilion dv9500t PC Notebook ?

HP Laptop black screen on boot, TV source works

\015 I have a HP dv9500t with a docking station. About two weeks ago, my laptop stopped displaying on the laptop screen, however it displays just fine on the TV that I have hooked up via composite (yellow cable). The laptop does not even display the normal bios or xp logo on the laptop screen; so I don't think it's a problem specific to explorer. For a while, if I waited long enough after booting, I could change the source using Fn+F4, but I cant seem to do that anymore. I have heard that there have been a lot problems with HP laptops and the nvidia graphics cards (which I have in this laptop). However, I havent heard that they still display on a TV source with this problem, so I'm not sure if this is the problem I have. I guess I'm just wondering if there is some way that I can restore the factory default display settings on my laptop or if there is anything else I can do. Thanks for the help in advance! \015

I have a hp pavillion dv 9500. When i have switch on a laptop but display is not coming in laptop lcd. i have open a laptop & disconecting a data cable of lcd. Now i attached external monitor & switch on a laptop. display is now working with external monitor.
\015\012i also cheque a laptop lcd, lcd ccfl lamp but all of ok. but till display is not coming in laptop lcd. kindly help me.
I have managed to solve this problem.\015\012It turns out that the cable connecting the laptop motherboard and the lcd screen had been bent too many times (from opening and closing the lid). When I examined closely, I found that of the approximately 20 small wires, over half of them broke with a small tug. \015\012
\015\012After replacing all of the broken wires, the screen booted up just fine.\015\012
\015\012Hope this helps someone else.
