My toshiba keeps jumping between source channels- any ideas

Did you try changing the source? It might be getting the channel from a source other than the TV.

If it's not the remote check to see if one of the buttons on the set is jammed/stuck

Yes, the main tuner is likely bad.

you will need first to configure the antenna sources where you want to program channels. and then you can add channel through your remote control. to add channels in the channel memory, first press MENU and open the set up menu and then highlight installation and press enter. a new set of installation menu icons will appear on the screen. open the terrestrial menu highlight channel add, and then press enter. the list of channel program from the antenna source that you select will appear on the screen. to add now a channels to the channel memory, highlight unchecked box next to the channel number you want to add, and then press enter to check the box.to save new settings highlight done and press enter.

As far as I know, you must enter the "-0", "-1", "-2", ... part of the channel number to jump directly to the digital channel.

Do it with the buttons on your TV scroll down through your channels after the channels run out keep pressing channel Video 1 should appear if u you need Video 2 press the channel button again.

you will have to program the tv to cable for it to work then it should start changing the channels and if that doesn't work then you might have a bigger problem with the tv

Hi, David.

This unit does not have a TV tuner built in. It can record only from a video/audio source such as a satellite receiver or cable box. That's why you can't find anything in the manual about programming a channel. It doesn't offer that capability.

Not the answer you were looking for, but that's what they give you. The only solution I can offer is to keep your old VCR or pick one up at a thrift shop, and use it as the signal source. Program it to come on at the desired time on the channel you want, and use its video/audio outputs as the source for your recorder. Program the recorder to start at the same time.

Kinda klunky, but it would work.

I just tried finding a manual for the toshiba and didn't find much. In the setup menu there should be an auto setup for tuning in channels. Cable or off-air. Let the system do an auto set-up to find channels available. I'll keep looking for a manual. Let me know how you do.
