I have a car radio/cassette from a 1997 Honda Accord that has an intermintent problem. Model number is CM6704BA, P/N 39100-SV4-A000-M1.
The radio dial always displays and shows chaning frequency for both AM/FM
All speakers dead, most of the time. I have it on the bench and seem if I heat it up with the hair dryer it will begin to produce a sound on speakers like amp is working.
When tapping or twisting stations will begin to come in and Stereo Light on FM will appear.
When it works it works good. Bump or twist the main board stations will disapper and rush sound form speakers remains, or speakers become silent with dial still displaying frequency, but no stereo light..
I have cleaned all sockets with DeOxit.
If I remove the cassette deck to trouble shoot componets beneath the deck, the display shows tape. I do not know what to jump to simulate the cassette deck being installed.
Does anyone have a Service Manual?
I think it could be in the area of the crystal or the large intergrated circuit. But it has been hard to determine what part of the part the connection is bad or flaky component is located.
I sure could use some help. I have doing electronic repair since the late
50's and have plenty test gear, scopes and sig generators.73
