BigPapa76 \, before tearing it apart connect an external monitor and see what it displays. If it does not, then read my answer to a very similar question :" this series has an issue with the GPU failing. Sometimes a reball can fix it, other times you may need a new logic board. Here is my answer to a similar question :"
This is a well documented prob with this series of notebooks and if you do a search on the Internet you'll find lots and lots of unhappy and frustrated people. The problem is the motherboard, and the symptoms include loss of bootup, VERY slow bootup, WiFi stops working, etc. is simply that the MOBO board overheats and fries the video driver chip. The cooling design of this PC is inadequate.
You might try this to verify.
1. Take the battery out and unplug the charger
2. With the computer lights OFF, press and hold down the power button for 15 seconds
3. Plug the charger back in and start-up the computer
to fix the problem you will have to reflow the graphics chip.
If an external monitor displays properly, you have a bad LCD.
Just for completion sake and pointing out things that were "discovered" about this since 2015. It is the same chip design as was used for the Xbox360, PS3 and multiple other products.
You most likely have issues with your GPU processor. It is a flip chip design and the issue could be the solder bumps between the IC and the substrate.. Combining this with a reflow with a heat gun may just complete a good repair. Check on here for the reflow guide. Also "remember that all that this kit is trying to accomplish, is to close cracked solder joints.
Here is a very "quick and dirty" explanation of what causes most of the RROD. It is not always a failure of the solder balls which connect the Flip Chip BGA package to the motherboard. It does happen and you can see why on here More commonly however is that the failure is due to the chip design itself.
As you can see the "bumps" are what actually connects the die to the substrate to make the chip complete. If these bumps fail the die does no longer make contact with the substrate and thus no contact with the circuit board. The chip has failed.
Here you can see the space where the bump has failed and no longer makes contact. We are talking microns of space here. So a bit of pressure on the top of the die potentially close the gap. Same with a reflow, it may allow some of material from the bump to reshape and starting to make contact again. The heating of cooling of the chip during use is what will eventually cause it to fail again.

I used to have this problem with my hp (exact same model) but I had lines on the screen. It was unused, until I turned it on again after loads of time, the screen fixed itself.

My capslock light will not blink but remaining lights is blinking and can't show display

@muneebkhan90161 read through the answers and comment so on here. This is most commonly an issue with the GPU and the design of that IC. There is no quick fix for this.

@muneebkhan90161 Pull your data off and scrap it. There's no fix.
Parts are NLA, and this was HP's era where they cooked things like GPUs which need proper cooling to death for fun. As you see, me and @oldturkey03 are very familiar with these lemons.
Any of these with the dGPU that SOMEHOW hasn't died is a pavement princess that was never used (but give it enough time, she's going to die) OR it uses the Intel GMA IGP.
If you bring me this mess of a laptop or ask me, my response is the same: "Bring an external HD or HD enclosure, I'm pulling your stuff off of the hard drive. I don't even want the laptop if you want to smash it with a baseball bat or run it over". They are THAT BAD. Outside of the DDR2 RAM and MAYBE the screen if for some reason you can find an inverter to make it external (and the backlight somehow isn't dead or on life support), these laptops aren't worth the parts recovery effort. Even the Socket M Core 2 Duos were mediocre. The fact I need to take the whole laptop apart for a mediocre CPU makes the recovery a waste. Unless I had an immediate target system, I don't bother with saving the CPU. These were so bad I considered them"roadkill" in my teens, even today I consider them roadkill at best. Any HP from this era with a Nvidia GPU is basically on that list, but all of the DVX000 2006/7 era laptops are on that list. They all had the same issue. I used the freaking LCD lid as a CLIPBOARD IN HIGH SCHOOL, minus the clip. HP logo was even visible -- you knew what it came off of and I think someone asked what it was.
The only time I will even waste time baking your GPU with a heatgun is if you have encrypted data that relies on Windows to recover.
