V14 (Might be a 13) Slimline with Matrix Infinity V1.88 Firmware (Authentic)
The screen bounces on Matrix Logo when you turn the PS2 on, nothing else bounces during boot up, or when playing PS2 games. The MI Menu & PS1 Games Bounce It didnt used to do this, i could play any game without issues.
I didnt change the firmware or any settings prior to this problem, It also bounces on Snes Station (not on the Snes Station Welcome Screen/File List, just during games) and PGen bounces no matter what. PS1 Originals and Backups both Bounce.
Figuring that something got changed i openned the MI Menu and tried all sorts of settings (ForceNTSC, Pal, Pal60, auto, ect) tried enabling and disabling PS1/2 Options like (Y Fix, Multi-Disc, ect) That didnt help, so i upgraded to V1.93 Firmware. No Change, still bounces on the Matrix Logo during bootup (prior to the PS2 Swirling Menu Screen), on PS1 Originals & Backups, Snes Station, The MI Menu & PGen.
Doesnt Bounce on PS2 Originals or Backups, or DVDs.
A Couple Exceptions to the Bouncing screen were the File List screen on Snes Station, Gameshark V4.11 for PS1 and several screens during the openning of a PS1 Game (Such as the Sqauresoft logo on Final Fantasy Games)
Chip was installed by a professional as a Premod system, It's an Authentic Matrix Infinity. I haven't dropped it or anything, i take great care of it, so Damage and Loose Wires are unlikely.
