Bob and all, thanks for the additional info. I did the BIG reset: no AC, NO battery ...NO results. Today I plugged in the power adaptor and I got a flashing light (one white followed by 5 orange) at the power adapter plug. Also I noted that when I depress the power push button it lights up for about 10-15 sec and then goes out. Otherwise all is dead. It still won't do anything when I pop the battery. I understand, through other research, that the flash code indicates a dead main battery...I ordered one. Now, I do think that the pwr jack is functioning. If any of you have more ideas about what's going on; I'm ready to listen. Thanks!
