It sounds that the main system control memory IC to this TV is faulty. Contact any service technician to confirm. This is not a user repairable fault. Gopakumar Gopalan Google
It's October 2012 and I have a problem with my exact same model of JVC TV which has worked fine since i bought it in January. In fact it has worked the best out of the four that we have in the house working off the same aerial until 4 days ago. I tried retuneing and then the problem expanded to more channels. I tried to reset to factory options and then do a retune but lost all the channels. I have again reset and retuned and I'm back with channels that I can only tune into for between 4 and 15 seconds before the screen goes blank. None of the other televisions are affected. Digital UK website show no works to transmitters in our area and JVC are impossible to contact. Their site sends one around in circles in a most frustrating and unhelpful way. I will not be buying JVC again. Any help offered would be gratefully accepted!
However, I do have a suggestion. You can hook up a vcr to your tv, then put the tv on channel 3 or 4 (whichever the vcr is set for) and change the channels through your vcr. You have to have the cable go first to your vcr and then out to the tv.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.
I am assuming that you are using cable and not an aerial/antenna.
On your concern "...channels do not tune...correct channel numbers...", it is possible that when you re-tuned the TV your setting was set to AIR or STD, try to re-tune again but this time pls verify that you are in CABLE mode. If on the other hand you are using aerial/antenna, then it is the other way around.
Channel 0 would automatically be your Audio/Video (which is where your DVD/VCR is connected). If you re-tune, chances are that Channel 0 ) would be back. To be on the safe side, pls power on likewise the DVD/VCR.
