Laptop turns on but no display

[Samsanxious_]

I have a 15.6” HP laptop 11th gen intel core i5 processor and solid state drive, I tried many many troubleshooting things from a YouTube video HP posted, nothing worked. When connected to my TV with an HDMI cord I can see my screen but other than that nothing. I reset the bios or whatever, did something with the drive when connected to my TV, windows button, B and power button. Please help im a college student who needs my laptop

Hello @Samsanxious_ 

Sorry to hear that you are having problems ... I would like to help you.

In the simplest case the internal display cable behind the screen is no longer seated correctly. It has come loose slightly.

Recommendation and solution

In your case: Service is required !
- The computer should be disassembled and checked.
- [Always recommended] Thermal paste for CPU GPU and bridges should be renewed
- [Always recommended] The function of the fan(s) must be checked

- The internal display cable that goes from motherboard to screen has to be checked or replaced

- The screen has to checked or replaced

- Short circuit test

- General cleaning ...

HP warranty valid -> Please contact HP Support for service check/repair.

If status (date) is wrong:

HP PCs, printers - Dispute a warranty status

If you can't do that, you should have it serviced by a professional notebook (chip level) repair store.

Good luck
