If you alewady tryed the DIFFERANT cable modes such as HRC, IRC or normal and the set still does the same thing then Jexx is probably correct in the diagnosis. BUT one more thing to check is that there may be an afc problem I've seen in many sets as if you turn on the tv first and then the cable box the set already tunded and wont retune. If you try to put on the cable box first wait a few seconds then turn on the tv and see if it tunes properly. But Jexx is right the tuner is defective most likly Good Luck
Right, but the problem is more likely the tuner unit-which the coaxial is hooked up to. If it was strictly the coax, when you wiggled the cable around, the image would probably come back fine. Youll have to get a tuner and solder out the old one, the solder in the new one. The tuner for your model is part QAU0305-001 found here: http://www.jvcservice.com/service/JMdlPrtXrf.asp?PgReq=DspDta&MdlNbr=AV-32432 Be aware that the problem could be as simple as a diode or cap...until it can be tested we don't know for sure. techman would probably know more about this model than I would.
