My world band receiver, Sony ICF-SW55 is acting up. When you power
on, it goes into a short calibration procedure and then the radio
comes on. Lately, it goes into CAL (displayed on screen) and then
shuts off after about 20 seconds. It started doing this from working
one day and not the next. Does it w/ ac power or batteries. Have
tried reset button many times. Does anyone have any help or comments?
Thank you!
