Im not new to modding ive done my ver5 (easy) but i tried install of the neo12 chip on my ver9. Long story short is after testing all my solder points over and over and checking everything i could think of , I gave up and decided to remove the chip to see if i could get my ps2 to work without the chip. OF COURSE IT DIDNT WORK! Now the ps2 lights up but doesnt boot , black screen. ive check anything i could think of , but still not working. this ps2 ver9 is for a show truck and I have got to have it reinstalled back in my yukon by show season and there is more i have to do to this thing before its ready .but thats in another thread. the point is i really need help with this thing please.
