My HP DV6-Pavilion Entertainment laptop doesn't work properly since yesterday.
My sceen is smashed, so I was using the hdmi cable but yesterday when I attached my laptop with the cable, my smart tv screen keep closing and opening again and again, like I plug in and out the cable.
That's happen only whenever I plug the hdmi cable with the ethernet cable!
So it's work all fine when the wire internet cable unpluggen.
I tried to check from "device manager" my network adapter (Realtek PCIe GBE Family Controller)
and I tried to check my display adapter but they're all fine!
What the problem may be?
