Hi to everyone . I recently received an SCPH-77004 (board : GH-052-51) with a modbo 750. This modchip was installed on December 2007 (so, i suppose before it works). But i doesn't read any type of backup (or import original games). It works DVD-Video and Original PAL games. Maybe the chip or wires are broken? Here's some pics : The connection looks like Ok (check with tester and there is connection)....maybe there is some fuse on the modchip? Thank you in advance and have a nice day !
