When I switch over to digital TV I am stuck on a single channel and can not change channels, see the digital menu, the guide text etc. In fact the only thing that I can change is the volume. The tv works fine for analogue television and was fine for digital until last week.

First, search for available air channels by going to you menu and then search for channel setup.
Second: change the option from Cable to Air Channels.
Third: after performing the channels setup you should be able to see free channels trough the air.
Using the television's remote control, enter the user's menu. Search for video input and change from cable to antenna. If still experiencing difficulty, visit the JVC website and download the owner's manual to learn the procedure of changing the video input type and deactivate the television's digital decoder.
The digital box should have a round threaded output connector on its back panel. These are usually marked "OUT TO TV" or "RF OUT" or something similar. There may also be a slide switch nearby to select channel 3 or 4 output to the TV. On some boxes the output channel selection is through and on-screen menu. You only need to connect the output of the digital box to the TV's antenna connector, then tune the TV to channel 3 or 4 depending on the box setting. Leave the TV on that channel all the time and do your channel changing on your digital box using its remote control.
If your TV has an AV input for connecting a device like a VCR or DVD player, you can probably connect the digital box that way. Most boxes provide stereo audio and video outputs, and you will get a clearer picture and sound if your TV has the input jacks. If your TV is not stereo and has just a single white input jack for audio (instead of red and white ones for stereo right and left), you'll need a Y-adapter to join the audio outputs from the box together to feed into the TV.
On the off chance you have a digital box with no RF output (I've never seen one since they need to work with older TV sets, but I don't know evey model), and your TV doesn't have AV inputs, you need an RF converter. The converter takes the audio and video signals from the digital box and generates the channel 3 or 4 TV signal that your set can pick up with its tuner. You can find RF converters at larger retailers and online.
There are two possibilities: either the channel memory has been lost due to the TV being unplugged for an extended period or the digital tuning system has a defective component. First thing to do is go into the TVs menu system and try to re-scan the channels. You may find that you can change channels after doing this. If its still not changing channel, the digital tuning board will have to replaced.
Well there is still a problem with the TV. I found that by unplugging the power cable that the digital channels worked. But, when I turned the TV on today the problem had returned, I had to take out the power cable again!
Beware: Although the process should be safe, it technically voids your warranty.

select the Reset option. Using the right arrow button at this point
will do a hard reset.
5 - Wait a few seconds, turn TV on
6 - you will have to rescan analogue and digital channel but it should be working now.
the problems due to the microprocessor on the remote reciever present inside the tv .i think the remote is normal working. as the only problem with your iinfra red reciever microprocessor.microcontroler circuit. Replace the IC to solve this. Check electrolytic capacitor coupled to the memory block of the micro processor. Contact service if you are not well verse doing all this rectification works. it is off high risk and caution thank you !
