This site is working fine! Did buy a manual for SX-EX25L and after a while I could download it and fix the problem. Nice and easy!
 ;
Complete manual as pdf-file in very good quality. Very helpful and fast availability.
;
Complete service manual in very good scanning quality with all schematic and PWB graphics as well as assembly & maintenance instructions. A slight drawback is that the rastering of the PWB graphics sometimes makes it a bit difficult to follow fine traces, but no showstopper.

5-5. Power down detection circuit
IC48 : Detection IC The power is supplied at CN16 from switching power supply unit. When the VP voltage become more than 22V, the voltage appears at pin No.2 of IC48 through the zener diode ZD2. The detection IC outputs "High" signal from pin No.6 and its signal going to IC45. Then, the signal "INTPWD" becomes "High" and going to GA2. The GA2 outputs "Reset" signal and reset the all GAs.
