Have you, or is it possible someone else who had access to this computer...
- dropped it, or dropped anything on it, or otherwise exposed it to a physical jolt ?
- spilled liquid on it, or sprayed it with liquid, or exposed it to liquid such as rain ?

Since the video last worked properly all the time, has there been a power failure event that happened while the AC adapter was plugged in ?

Those things are the most frequent reasons something inside the laptop has been damaged.

Try plugging in an external monitor
If there's nothing wrong with the display on that, your display assembly is damaged or defective , or the wiring between it and the video adapter is damaged.

Laptop no video (or video problems), and battery, AC adapter, power jack T shooting.

See response 1:

DO NOT plug in or unplug a monitor's video cable into / from a video port while the computer is running. Doing so can damage the monitor's circuits and/or the video adapter's circuits.

Some laptops will display on an external monitor without you having to do anything.

If you get no video on an external monitor, some laptops have a key combo that you must press to toggle the display to external video only / built in display video only / sometimes both - see the Owner's or User's manual for the model.

Thank you for responding Tubesandwires

This is my 21yr old sons laptop, he says none of those things have happened. (I cant be sure lol )
I plugged in another monitor and that display is fine. I guess his display is damaged? Any way to fix, that does not cost a lot?

If other people have access to the laptop, he can never be sure it wasn't damaged by one of them and they didn't tell him. ( I would - I suspect most people would not.) I also suspect most people who use laptops do not plug the AC adapter into something that protects against power spikes and surges.

The cheapest possible fix is to replace the wiring between the video adapter and the display assembly.
If that doesn't help, the display assembly is either inherently defective or has been damaged - it's much more likely to be the latter. Whether it's worth the cost of replacing that depends on how much the laptop cost in the first place. He could replace it himself to save on labour costs.

A failing backlight or defective voltage inverter causing his problem is extremely unlikely.

Hi Mikkis, if you decide to replace the screen, check out ebay as often they can be found there at reasonable prices.

I would choose a new one, rather than used.

You can probably google and find a video of how to replace same.

Please advise back what you decide.

Good Luck - Keep us posted.

I am sure you are right, it very well could have been knocked around by accident by a friend without our knowledge.
So how do I get the parts and instructions to try the fix you suggest. I would very much like to fix it as he has not really used this laptop much at all, it was a graduation gift in 08 for college but he only went for a few months and works all the time in the heat and air business. Which is why I'm doing all the research for him, he has no time and for some reason he thought the hard drive was shot so he just figured it was done. I wanted to investigate. If I can get all the info to repair I am sure he can do the work. About how much would this cost?
Thank you again for all your help

Search the web for someting such as: HP Pavilion dv6915nr display assembly, or use the laptop series number (see the Maintenance manual info below).
Note that I recommend you get the wiring for between the video adapter and the display and replace that too, or at least have it on hand for future use. You could try getting both and trying the wiring first - if that fixes the problem, return the display assembly, however, examine the policies of the seller
When you open up the laptop there may be a part number label on that cable. If not, the part number for it may be in the HP Maintenance manual for the series.

HP usually has the Maintenance manual for the series available to be downloaded, in the Software downloads for your specific model. That tells you most of what you need to know regarding opening it up and replacing parts.

What may not be mentioned is after you remove the screws holding the case together, there are usually hidden plastic latches and matching hooks on the other side they latch into at the seams - you need to insert something metal and thin and at least , say, 1/2"wide , to unlatch those latches, the width being necessary to avoid damaging the plastic. `

"About how much would this cost?"

I don't know. As someone has already mentioned, the cheapest prices may be on ebay.
Generally, the older the model is, the cheaper the display assembly becomes.

It's NOT a good idea to buy a used display assembly, unless the ad says the backlight has been professionally replaced. Backlights - CCFLs - have a limited
life span - a used display assembly - the backlight in it - will have a shorter usable lifespan.

That is a lot of very good info for me. I am going to pass it all on to my son so he can try to get this fixed. We will try the wiring first. My fingers crossed, hope that does it.
Thank you for all the much needed help.
