i got the sodering right, i used.022 Silver Bearing Solder, idk if that worked good but we were able to start the PSP and screen perfectly and then we took out battery and put faceplate and use battery to turn on and it didnt then got power plug and didnt either, tried charging battery same thing. what happened everything went well until this
EDIT: nevermind my bro found the problem, he soldered it and left a huge tip sticking up and was touching the brace, thats y it didnt power on, he found out when he unscrewed and it released some of the pressure and let the PSP turn on. thnx for ur help 4dP, u too psp339 u came in at the point where i was just gonna sell the damn thing and was very deppressed, after u showd me those pics my bro soldered with no problem, we practiced on some old circuit board from a phone line, thank you both, i will never forget this. thnx
