The display on the radio in my 1994 Accord EX doesn't work most of the time (unable to see station) and the tape player makes the tape jump every few seconds contantly unless the display is on before putting the tape in. The odd time giving it a good smack seems to help but other times does nothing. Any ideas as to what's wrong with it or how to fix it, it worked fine up until this past January, I'm wondering if some really cold -40 nights may've somehow affected it. Any input is appreciated. Thanks.
