How to remove a ''white'' dead pixel?

Thank you Duane_D for reading this. I'd be happy to provide any additional information the best I could, when I receive a private message from an identified HP contact to get these issues resolved, even if I had to fix it myself but with HP guidance. I appreciate your respond. Thanks

I am wondering if you ever got a fix for your laptop?

Interestingly, my laptop developed a problem with a hissing noise when using earplugs and then a short time later (maybe days later) one third of my screen seems to have dead pixels.  There looks to be a bleed of black pixels at the bottom right hand side of the screen and then the rest of the affected part of the screen is covered in white and multicoloured lines.

It is best to start a new thread for a new issue, especially when the existing thread has an accepted answer and is therefore marked 'Solved'.

Most earbuds are extremely sensitive, typically picking up low level noise from the internal sound cards of many notebooks. Internal audio hardware is in a very difficult environment for small amplitude analogue signals: electronics crammed into a small case with a lot of other electronics all of which can generate noise, and with which the audio hardware has to share power supplies and ground planes. You will often get much better performance from outboard audio hardware, such as a USB DAC and headphone amplifier or a more fully featured USB audio interface.

It is hard to comment on the screen without seeing a picture, but it sounds like you have suffered some sort of hardware failure - perhaps the display panel or the cable between the system board and the display panel. If you have any warranty remaining, I would contact HP to discuss that situation.

Yes, I had to send the laptop back to HP and they've replaced the screen, there was no other way to fix it.

Its rather inconvenient but if your laptop has multiple issues, the best option is to open a repair case and have it sent back for a repair.
