PS2 FAT has no video/audio after removing the Matrix chip
The PS2 Fat console was displaying video and the Matrix chip logo appeared, but it just stayed there—it wouldn't boot up. Since I wasn't going to use DVDs to play games, I decided to remove the chip by desoldering each joint carefully (without lifting the traces and making sure to clean the board).
Then I put it back together and turned it on, but now it has no video or audio.
