You may be able to get around this via a digital hd tv decoder box and then have it on a hdmi input on the TV as a backup to the cable if you can't have both cable digital channels stored and aerial digital channels stored
With the tv cable hooked up do another channel scan and that should find all the channels again. As for the DVD there should be a source button or a tv/video button for that :) hope this helps :)
First: If you do not have a cable hookup, if you are using an antennae, you should get a converter box.
It handles the scanning, the decoding of sub-channels (I have four OPB channels), signal strength filtering. It's remote, controls both the box and your TV.
It hooks up between your TV and antenna. Set your TV to channel 4, click the on button. The first time menu comes up, scans the channels and lets you know when its done. You'll find channels you never knew existed.
I carried my Westinghouse TV to the basement. Unplugged the antenna from the digital converter box and connected it to my digital TV. I then re-scanned for channels and found channel 9. After carrying the Westinghouse TV back upstairs, I connected the original set-up and tuned to channel 9 which was now showing on the screen as no signal. From that point I moved my VHF dipoles until I had located the correct position for reception. A little labor intensive, but I was fortunate to have another antenna that was receiving channel 9.
I always tell people to carefuly read their instruction manual and consult the product tech support before determing that there is actualy a fault with their unit.
If sounds like the tuner module or the controler board for the tuner may be failing, or there is a power supply distribution fault to the tuner section and or its controler. This has to be service by the manufacture.
One of the criteria I recommend when people buy an expensive appliance or TV is to make sure that there is local authorized service. I also recommend an extended warrany for expensive items. The warranty is like insurance. You may or may not need to collect!
