How do I retune My toshiba ct 90240 hd tv

SOURCE: Tuning a Toshiba CT 9689

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.

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

i think i get the jist - you've moved, and now you're missing a couple channels. from what you're saying, i assume you are using a digital converter box, or have a digital ready tv. i personally have seen many problems since the digital change, specifically loss of channels. even though digital tv is supposed to be 'all that', and it is fine when it works, the quality and placement of your antenna is still critical. you are still receiving a signal on the same channel, only with digital, they have reduced the bandwidth. this action was not done with the consumer in mind, it was done to free up air space for other communicatiomns. try an amplified antenna [available at radio shack for about 20 dollars], and try different positions. if this doesn't work, you might try an outdoor antenna. with digital signals, if there is an obstruction between you and the transmission site, rather than getting a weak, snowy picture, or shadows, as you would back in the days of analog, your receiver will simply not receive the station

SOURCE: No BBC channels available after retuning Sony Trinitron TV

When TV channels are moved from one frequency to another frequency that was previously used by a different channel (sorry, but there's no simple way of saying that !) as has happened recently in th UK, some digital TVs and digiboxes struggle to sort the channel list out properly and channels can go missing as you describe.

If your equipment has the option to delete all currently stored channels (normally in the tuning menu options) then do so and then do a full re-tune.
Sometimes, this solves the problem as the equipment is no longer aware of any previous use of a frequency and just loads every channel it finds.

If this doesnt work, or your equipment doesnt have the option, then there is normally the option soemwhere in the menus to retore the item to "factory defaults/configuration". This will clear all previously stored channels and after a full re-tune your missing chanels should be there. However, any other configuration changes you previously made, e.g picture size, output type (RGB/NSCT/etc), etc will be lost and you'll need to set these again.

NB. some regions of the country have lost some channels temporarily now until after the switch over programme completes at the end of 2012. If you visit the Freeview website, this will tell you if your area is affected.
