The laptop turns on but the screen remains off, if I connect the laptop to a second screen it works without a problem. What suggestions could I try?
Is this a good question?

Hi @juan25026
With the laptop turned on, shine a flashlight at an angle close to the screen and check if you can see any images on the screen at all.
They will be very faint if they are there so trying this in a darkened room may help.
If you can see images then there's a backlight problem with the screen. This could be due to a faulty backlight power supply circuit on the motherboard, a faulty EDP cable/cable connection between the motherboard and the display panel or a faulty LCD panel.
If you can't see any images then this this could be due to a faulty EDP cable/cable connection between the motherboard and the display panel or a faulty LCD panel.
Here's the hardware maintenance manual for the laptop. Go to p.61 to view the procedure to remove the LCD unit. This will allow you to inspect the EDP cable/cable connections and also to replace the LCD panel if that is the problem.
If the problem is a faulty part that needs replacing e.g. cable or LCD panel, there's a parts list in the manual. Search online for the part number (FRU number) for the wanted part, to find suppliers that suit you best.
