Toshiba 42 lcd cannot delete channels I use the manual channel set and select Not Viewable for channels I don't want to see. Then as I click through the channels, the deleted channels show up again.

select to auto channel then press the + volume.

set your TV! go to menu then click auto search!

the set should have in the menu a way to manually add or delete channels, consult the owner manual and or look for that feature in the sets menu.

no you do not need to upgrade the firmware, the channel selection is based on the amount of signal strength it gets, older analog systems would select it as long as there was a slight amount of modulation as for digital it goes by a percentage, if you wish to set these channels then go back under the setup and select manually add channels then you can add any one you whish reguardless of signal strength.

Hello
First of all reset the TV. for that

press and hold the POWER button
on the TV control panel for 5 or more seconds to reset the TV.
Then connect the TV tt any source like outdoor areiel or cable box etc, select the appropriate input, and retune the TV. First of all, connect it to an external antenna, and set it to autotune.

• You must configure the ANT/CABLE input source before

programming channels (-left-hand column).

• If the ANT/CABLE input signal type is set to Cable, the

automatic channel programming process erases channels

that were previously programmed into the TV's memory.

• If the ANT/CABLE input signal type is set to Antenna, the

automatic channel programming process adds newly found

channels to the existing set of programmed channels (and

does NOT erase channels that were previously

programmed into the TV's memory.) To remove an Antenna

source channel from the memory, you must manually delete

it.

• To tune the TV to a channel not programmed in the channel

memory, you must use the Channel Number buttons on the

remote control.

• Programming channels when the ANT/CABLE input is

configured for Cable will take substantially longer than when

the antenna input is configured for Antenna. This is normal;

however, once channel programming is finished, you should

not have to repeat the programming process again unless
your Cable TV service lineup changes significantly.
Find out the received channels are clear or not. If they are clear, your TV is perfect, and the input device you connects ot the TV is faulty. OK.

After u deleted all the HD channels u don't want.Tries unplug,replug the cable box back like about an hour.For the box to upgrade it softwares,should be deleted all the HD channels u deleted.

Which specific model from Toshiba do you have? There are several 42" TVs released with the Regza name. Most of the manuals can be found on the Toshiba support web site. http://www.tacp.toshiba.com/customersupport/

The one that I have allows for the channels to be set from the On-Screen Menu. In the TV mode, press Menu (there is a Menu button on the side of the TV). Navigate with the arrow keys (CH+, CH-, Vol+, Vol-) to the Setup menu and highlight Installation and press Enter (the Menu button is also the Enter key when using the buttons on the TV). Then highlight Channel Program and then Start and press Enter. When the search is done, press Ch+ or Ch- to view a station. To add or delete channels, use the Channel Add/Delete that is one line below Channel Program. Use the enter key to change the check mark status next to a channel. If adding a digital sub-channel not previously found, enter the number manually on the remote using the 100 key to add the dash. If the channel isn't found, an error message will result.

I hope this helps.

what are you trying to do ?
if your trying to re scan your channels then go into youe setuo menu and rescan channels in cable mode if your on cable or antenna select air

Just go to the main settings. You will see an "autoprogram" option. Select this and it will scan all available channels and delete non-airing channels

On your menu, go to the channel settings. Go to add/delete channel. You will have to add this channel manualy. The tv might have went into autoprogram mode and deleted it.
