Default HP Laptop Turns On But Screen Is BLACK

I have a 4-5yr old dv 6500 HP laptop. I recently had 2month old battery crap out on me (don't know if this is related to the problem). However, soon after my battery crapped out i started having problems with my laptop screen. First it would go out/black if I wasn't using it. (during this time the laptop is being powered thru the outlet). Next, i start seeing lines on the screen in addition to the black screen problem. By lines I mean the screen would get distorted and soon the lines would turn into a colored blur. I definitely thought this was a screen problem where it may have crapped out. But i would re-boot and power back on..and the screen would come on..only to succumb to the lines and blackouts 10-30minutes later. this problem with the lines and black screen went on for a week and a half. Now the screen remains black and will never come on..all while the computer is on and I can even hear the computer reaching the sign on windows screen (where I enter in my password). I connected my laptop to my tv and it would give me an image on the tv..but once my laptop went to black screen..so did the image on the tv. Fom this, I am pretty confident it is not a problem with my screen but something else.
Some of these problems may lie with the graphics card or RAM? Am I right in saying this? If yes/no how do I go about repairing it inexpensively?

I would appreciate any help really!!

Thanks

Sounds like a defective GPU, I think there was a class action law suit over that a few year back.

2 years ago, I had this same problem with not just one but two.
I ended replacing the mobo (integrated graphic chip set) only a few months later they both crapped out on me again.
Ever since I vowed not to ever buy any thing from HP again.

I believe it was the nVida Quadro NVS 110M on numerous Dell and other laptops that was faulty and causing major headaches for folks with it present in their laptops.

I don't think it would take 4-5 years to become an issue on your laptop.

Remove the battery. Remove the power cord/adapter. Press and hold power button for 60 seconds.

Reconnect power cord only. Try powering on and tell us what happens.

Hey guys,

Thanks for all the input and suggestions. Would this piece of information change anything? ...A week or even less before I started having the black screens and blurred lines, I installed a Nvdia driver/graphics update onto the laptop.

"Wedge1", i believe i have done that...but i'll give it one more try.

I just talked to hp about the faulty gpu. They told me to call the recall dept. and see if my laptop falls under it.

Thanks

Nothing you done have caused this.
The Nvidia GPU was defected from the factory, and don't go spending money replacing the motherboard either. All motherboard with that Nvidia GPU will die on you.

The claim period is over, lucky you, you now have justification to buy a new laptop.
I am stuck with an old ThinkPad that just keep on going and going ;(
