|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.
