Display in bad state on stored 48G

[Jlouis]

Yes, I've seen it. Many times.

It's due to heat. I see you live in Brazil, like me. Depending on the city you live, the temperature can lead to damage the display, although HP specifies IIRC 40°C max temp, I've noticed that 35°C is enough, combined with humidity, to damage the display. Specially the black screen.

I think it is repairable. There's a gentleman in Curitiba that do this repair, see here.

You can substitute the display also. HP 49g, 39g, 40g can be donors, with the better contrast black screen.

Good luck!
