The monitor no longer receives a signal

[Diego-]

Hi everyone, I own an HP Pavilion 550-100nl. Today while I was turning on the computer, the monitor to which it is connected via HDMI no longer receives a signal. I tried to connect another monitor to the computer but it does not work. While the monitor I use for the Pavilion, connecting it to another computer works properly. I think it's a driver problem, but how can I install them on my computer if I can not see the screen? Thanks in advance.

I tried the three solutions you showed me and I could not do it because the computer does not recognize the keyboard is connected via USB and Bluetooth.

Hi there, thanks for trying. This would confirm a hardware issue and the computer needs to be serviced. I'd suggest you contact the Phone Support team to know more about the service options for your computer.

Have a good day!

Some time ago I advised in this forum to use this procedure, can you tell me if it is possible to do it?

"Disconnect the AC power from the computer.

Remove the side-panel, to expose the motherboard.

Physically remove the add-in Radeon adapter.

Connect a "known-good" monitor to the integrated graphics port.

Reconnect the AC power.

Power-on the computer.

Now, do you see anything?

If not, it's time for you to take the computer, and the add-in adapter, to a professional computer technician, and pay for assistance."

Hi there, thanks for replying. Those steps are not recommended if you are not comfortable opening the computer as it might cause more damage. I'd suggest you reach out to the Phone Support team in your region regarding the service options for your computer. 

Have a good day!
