Solved! Lenovo y720 screen problem

[sayralihovac]

Hello, can someone tell me what could cause this problem Im having with my lenovo y720. Laptop is not older than 5 months and yes I have warranty and will take him as soon as I can. But I would like to know why this might be happening to brand new laptop, it happens only when my screen is waking up from sleep.

it could be a loose cable (the cable that connects the display to the motherboard). It could be the display itself. Or it could be the graphics card/GPU is defective.

Best to let them look it over since it is still under warranty.
