first make sure u havent bridged anything on the ps2
then remove wires from neo2 chip(if prefitted wires make sure u record which wire goes were) ensure end wires which u remove r insulated from touching anything
now your ps2 should boot
if chip part installed it gets activated but cant function as wires r missing so ps2 doesnt boot
certain wires can b left off and neo2 still has most its functions
(tray doesnt open for ea swap i think is pin2 (not sure) but pin 8 i think must b connectected
sorry i not neo pin expecheck no bridge if no bridges remove wires from neo2 as i said let some one refit it later
if no bridges the ps2 will boot again
my advice bin neo2 before it destroys your laser u lucky u not used it yet
buy a messiah not cheap but worth every pound it costs
