Audio Systems: alpine car stereo, alpine car stereo, cda 7840


Question
My 1999 alpine car stereo (CDA 7840)works perfectly some of the time. Most of the time however I'll turn it on and I can't hear anything unless it's turned up almost all the way.  Sometimes if I wait long enough it suddenly works again. Could you tell me what might cause this?  

Answer
Hello Joe,
I would say by what you told me that this radio may have a defective solder connection/s. If it takes a while to start working the problem might be a heat related connection, the defective connection will work after the circuit board heats up and makes the connection work as long as the radio is warmed up? if you need to contact me in the future you can Email me direct at: tdeser@zoominternet.net
