I have the Panasonic DFX700U receiver (glows blue at night) it has a manual flip face.
Anyway, for the past month or two now it has been pumping out the nastiest distortion ever and it stops when you tap the face cover on the receiver but then comes back a few seconds later.
I pulled out the receiever and checked all of the wires and made sure everythign was plugged in correctly and made sure no wires were touching and i removed the ground wire and then grounded it right back where it was (man theres nowhere else to ground it)
I screwed it back in and now it still does it. I can't exactly send it back to the factory because I dont have a fucking receipt for it anymore. Any ideas???
Could it be the connections on the flip face?
The only other slight peice of car audio information I can tell ya is that I shaved my antennae off my car and the cord for the antenae is just sitting in my trunk and it's still plugged into the receiever, but that shouldn't bother me while im playign a CD right??
