Hi, I have a Sony cybershot digital camera DCS-P1 (mine) that spits out E:91:01. I assume its has to do with my flash unit, because it does not work I can still used the camera and all other functions work, but does not flash. I tested the strobe, capacitor & trigger transformer (all OK). Need a print of trigger circuit and/or flash circuit. I also need the procedure to reset the codes or address for these functions. Thanks, Autolectrics Randall Torda 284 Makua Street Wailuku, HI 96793 808-244-3064 lectrics284@xxxxxxxx ----------------------------------------------------------------------------- Lost Password: http://www.tech-assist.org and select "Login Problems?".
