My 2400h will no longer power down. also, the frequency dislay only displays 170-180mhz, which of course I can't use anyway. This is after replacing a blown 2200 ufd cap on the input power line
forgot to mention--accidentally reversed polarity. After removing cap, powered up and found other problems. Read the manual over again, found the way to set to factory defaults. that took care of it. working fine no. thanks
