After installing Magic S+ on my V12, and Summone's fix using 2.0k resistor on "683" (tracking) and 4.7k on focus, I got a black/blank screen. Holding down reset put Magic S in sleep mode and everything worked fine.
I then installed the "blank fix" which is simply capacitors on the "A" and "?" (forgetting). I then could boot to Browser, etc. First time installing PS2 backup, it loaded fine, then started skipping and finally froze. Subseqeuntly, could read that PS2 disc was installed, but would freeze on loading. Same with PS1 discs. Audio and DVD still work fine with Magic S active.
It seems that heat is the problem and possibly related to the Summone fix. Should I try a 1.8k resistor for the tracking coils? I would think focus is fine since I am reading the disk initially.
