Screen problem / Processor problem ? [FP3]

Yes it sounds like the display to main board contacts.

To be careful not to burr the cut in the screw head it can require a lot of pressure so the screw driver doesn’t slip.

Once the head cut is damages i.e. rounded there are a few ways to get a grip

  • laying a rubber band between the driver and screw allows for good friction

  • Use a very sharp edged simple screwdriver that can be dug into the head with pressure.

  • in a worse case take to a phone repair shop for someone with better skills and equipment.
