Let me be a little more clearer because my first post was rambling. I checked many times and all solder points are clean and connections are correct: Just finished installing Magic V 50k. First time installing, moved GND to another GND point: boots into PS2 menu, but gets black screen on booting PS2 original game and detects all inserted disc as PS2 format disc and does not run any other format disc. Second time I reinforced GND and 3.3V with thicker gauge wire and moved GND and 3.3V to other points (GND on voltage regulator, 3.3V to 3.3V source for Mars II modchip): boot into PS2 menu and plays PS2 original game, but still detects all inserted disc as PS2 format disc and does not run any other format disc. Keeps givming me browser when the disc is not PS2 format. Also, PS2 logo (the one in white saying Playstation 2) when first booting a game is garbled =( . Also, I cannot get it to sleep and the operating procedures from Magic do not work with dvd movies or sleep. Please Help. Thank you. Today, I just tried it again and it is working as it did the first time I put it back together.
