A special PCB design with one PIC and 4 pcs of diode for protection all PS2 SCPH-700XX console. The new fix is the same function to slim fix VIII ( based on the idea of Matrix-FIX and on the previous version of Comsoft & Albert 35 ) But you must cut 1 wire of PStwo mainboard and solder 6 wires when you have installed for the total ultimate full protection. Features: 1. On boot the pic of the fix waits 1 second for the pstwo to initiate. 2. Check to see if the CD Tray is open, it does IMMEDIATE SHUTDOWN PSTwo. ( This is the test mode, which enables to check in anytime if the fix is working ) 3. Checks for INT for every 250ms at anytime if INT is high, the pic code jump to watchdog routine. 4. If 1.5 second from boot have passed and the INT is still not active then the PIC CODE mute the RS2400FS and by that disable any current flow to the lens and to the CD/DVD motors. 5. If 3 seconds from boot have passed the PIC CODE shutdown the pstwo to save the lens. 6. Clip the input tracking signal from the CD/DVD controller to 1.2 voltage (more stable and safe)
