Hi,
Please restart the computer and press the F2 key to access the BIOS setup. If the issue persist in the BIOS also then the issue is with the LCD screen, in that case service will be required to replace the LCD screen. You may either contact Sony Service Center at:

Based on the information, it seems that those are dead pixels and a LCD replacement will required.
The following are the Display part numbers:
A1062138A- Sharp Display Model# LQ170M1LA04
