SCPH-1001 wont go past startup screen

Post by Mrmet2087 » September 13th, 2021, 8:22 am

Picked one up for free. Boots to the white screen but wont go beyond that. Stays there forever and wont even go to the bios menu. I tried to reflow the bios chip with some heat to see if that would re-set the chip, but nothing. Am I dealing with a bad bios chip?
