1994 accord radio
 

I bought an 1994 Accord Wagon LX and it appears that the radio does not work
all the time. Sometimes it does and sometimes it doesn't, although the power
lights and display are always on. Also the cassette doen't work when the
radio doesn't work, although you hear the rotation of the cassette
mechanism.
I've heart from a friend that she had the same problem with her Honda.

Does anyone know what the problem is and how it can be fixed? (I don't want
to go to a dealer for a radio worth $25). I prefer not to buy a new radio
because I'll have to sell the car again in 6 months, unless it is a used
Honda one.
