A family member has got a laptop that is about a year old, an Acer Aspire 7535g
The problem with the laptop is that it is getting pink banding on the screen, this does not always happen but often does. Once the banding shows on the screen it tends to stay into the laptop has been restarted.
While the banding is visible any pressure on the base part of the laptop alters the pink banding. for example: no banding on screen - light pressure on base shows light pink banding and hard pressure on the base shows deep pink banding.
If their is banding on the screen a light bit of pressure on the base reduces the banding on the screen and if u put a lot of pressure on the base the banding vanishes, release the pressure and it comes back.
No loose cabling or parts and everything up to date.
u might want to try and disassemble the laptop screen to see if there is a loose connection with the motherboard... while u have it apart, if the connection is solid, you might want to change the voltage regulator, or perhaps the screen as well
