Changing channels on its own - Toshiba 19AV500U 19 in. LCD HDTV

• If both the STA and AP support channel change notification, the AP sends an action frame (802.11h) to the STA after the AP switches to a channel. The action frame is used to notify the STA of switching the channel immediately or after n Beacon intervals. The STA then switches the channel and retains online.
• If the AP supports channel change notification but the STA does not support channel change notification, the AP sends an action frame to the STA, notifying the STA of switching the channel immediately or after n Beacon intervals. The STA does not process the action frame, and goes offline after the AP switches to the channel.
• If the AP and STA do not support channel change notification, the AP switches to a channel and the STA goes offline.

To see if the problem is with your remote control, go to the receiver and use the channel up/down buttons on the receiver itself. If you can change your channels with the buttons on the receiver, the batteries in your remote control probably need to be changed.

If you can't change channels from the receiver, turn off the receiver. Then unplug it for at least 15 seconds. Plug the receiver back it and turn it on. Again, try changing channels from the receiver itself.

Tune to a channel, and while programming is playing, try tuning to the missing channel by entering the channel number on the remote control keypad to see if channels change. Do not try to select the channel from a channel list, program guide, or favorites list.

If this approach takes you to the correct channel, you need to adjust your favorites list function. Press the "guide" button on your remote. Look for a button on your remote called "fav" or "list." Press it several times and watch for an indication at the top of the guide that you are moving from "all channels" to a particular favorites list.

If you are locked on one channel only, your Channel Lock feature is likely active. Consult your owner's manual to unlock the rest of your channels. See your owner's manual for information on managing favorite channel lists and locking out channels. Enter your password, if necessary.

Lots of possibilities. If you are using the remote, try also using buttons on the TV to change channels. If TV buttons work, the remote is broken or perhaps try changing batteries and cleaning battery contacts on the remote. If neither work, lots of other things to try. You may need to set preselect channels, so your TV thinks there is only one channel out there until you do. If you are on a cable box you just need channel 3 and change channels on the cable box. I can't tell what you mean by "audio changes with the channel" ... if you mean that when you try to advance channels, it increases volume and moving down in channels lowers volume that would be strange -- if you are using a programable remote it might not be set correctly (try another programming code). The "blurred" picture is probably symptomatic of having the set on the wrong channel, and if you could set channel it might clear up ... I'd start with getting channels to change. If you need more help, give the brand and model of TV, say if you are using a remote (original or programable), and what the 'audio changes' comment means in more detail. Probably worst case is that your tuner circuit is fried, but don't assume that without more diagnostic.

AVEIS LT15AP3; WHEN CHANGING THE CHANNEL BY LAST CHANNEL OR BY PUTTING IN ACTUAL CHANNEL , IT DOES NOT CHANGE TO CHANNEL I PUNCHED IN BUT TO CABLE CHANNEL 3. IF I TURN TV OFF AND HAVE THE CHANNEL I WANT ON, IT COMES ON THAT CHANNEL. THEN IF I CHANGE CHANNEL IT GOES BACK TO CHANNEL 3. HELP????

Auto channel search is your friend. Once the tv has been through it and finds active channels, your channel button should work the way you envision.

Try getting a universal remote and use that to change the channel.

If you changed the RF out channel setting on the DTV converter and now can't see the output of the converter try changing the channel on the TV set. THe DTV converter boxes are designed to output either RF channel 3 or RF channel 4. If you were on channel 3 and changed the converter output to channel 4, you will have to change the TV channel to channel 4 to see it again.

Hope this helps.

Did you follow the suggestion to rescan your channels in the setup?

The button on the remote next to 0 and below 9 has to be depressed to _ _ before you select any 2 digit channels. I had the same problem and accidently figured it out. Hope it helps. TC
