ok so i have a JVC cd stereo and lately the thing is screwin up bad. I'll be listening to a cd and all of the sudden the cd will stop and makes a noise like someone is scratching a blackboard. Then it will come back on 10-30 sec later. I thought it might be just the cd, but if i switch from cd to radio when it cuts out, the radio doesnt work either (it makes this high pitched noise). It seems like the stereo loses power for a sec or something. Maybe the connections are loose? Any ideas? Thanks
