Tv changing channels on its own

After a few minutes when I turn the tv on, it changes the source to tv channnel1. then I try to press the source button to return to hdmi or video and it is like someone is holding the down button, so it goes by itself on all the sources. if I press ok on one of them as it goes down automatically then I returns after a second to source tv channel 1.

SOURCE: TV changes channels itself

Have you checked to see if any of the front panel buttons are depressed and stuck??? this is a big problem these days?? I have also found the infared remote sensor to be bad on some sets that do crazy things all by them selfs.. A funny storry once i had was a customer called me after her mother called some goast finders as her maggy projection set would go on all by itself andf the channels would change and the volume would go up and down all by its self. funny thing I had a set just like thast in the shop at the time with the same problem and I scoped out the output pulse from the infared reciver on the set and that was putting out noise on the data line and caused the set to eratacly do all sorts of weird stuff. get the point?? its a stck button or the remote sensor is bad.

SOURCE: mAGNAVOX mODEL 27ms3404/17 shuts down

first place to start on this chasss is with a known failure in the horizontal circuit. there is a capacitor 2455 and 2 transistors locations 7461 and 7463 that have caused a wide variety of failures. i would recommend replacing these components before proceeding as they could be the whole of the problem.

SOURCE: television turns on and off, turns up volume and changes channels

Usually sets that are "possessed" in this way have defective "tact" switches. Replace all switches and that should take care of the problem.

When pressing menu on remote control I do not have a tv section listed to tune in channels


The TV channel settings Menu is usually only available when the Input is on TV. Look for a Source or Input button on the TV or the remote. Press this button and try to change to the TV source option.

Please add a comment with the make and model of the TV for additional information. (Unfortunately, many TVs don't let you change the source after pressing the Menu button and they don't always have a Source/Input button on the TV. Additionally, some replacement remotes don't even include a Source or Input button. For those with an Input button, you may need to try other codes to see if any will correctly work with the TV.)

How to change input on tv without a remote


Which TV do you have? Some will have an Input or Source button on the front panel. A few will have an option to change the source from the menu. Both of these options require the front panel lock to be inactive.

A few older TVs allowed you to find the A/V input by pressing Channel Down on the front panel buttons until you passed channel 2 (or Channel Up until you nearly reached Channel 2). This option wouldn't work if the A/V inputs had been deleted when someone minimized going through unused channels.

If the Source or Input button was only available on the remote, you will need a universal remote that includes this feature. These cost a bit more than the lowest end remotes. Then you will have to try all of the codes to find the one that makes the Source button work with your TV. (Several codes may work for On/Off but not the change input.) The Universal remotes that can be programmed from a computer (USB connection) will be the easiest to set up. Remotes.com may have a replacement original or substitute remote for your TV that should work for all of the TV functions.

I hope this helps. Please add a comment with the TV make and model for specific options for your particular TV.

I have a Toshiba TV/VCR/DVD combo, remote WC-FN2. I can turn the TV on,change volume but can not change channels. Help! Thanks,


Some tv remotes will do this if the TV is programmed to skip all but one channel (or the last scan for channels had only one active channel - like a tv connected to a set top box (3,4,60)).

See if you can navigate to other channels by typing in a channel number. Also check if the Tuner is the current source of the video signal by pressing the Source or Input button. If you have a menu button on the TV or the remote, try rescanning channels or editing the channel list.

I hope this helps.

Can't get the tv back on the channels properly after watching a m


Change the input, look for the button on the remote or on the TV itself. Just changing the channel on the TV after powering down the VCR should also work.

Remote stuck--can't change channel or turn off TV


Pull out the power plug of your TV and don't use it for few minutes. Remove batteries from your remote and keep it without batteries for few minutes. After about 15 minutes your TV and remove both will work fine.

Mintex 37 inch wide screen. remote is working however cannot change channel, input source or volum. only turns tv off. The buttone on tv doesnot work connot change input source or volume


Check if the remote is in TV position, that is, because most of the remote controllers have the feature that you can program them for use with another devices. Make shure that one button that says "TV" in pressed and released once before you try to change any function on the TV.

Channel changes automatically


There are a few things that can cause this. #1 most often cause is either something spilled on the channel button or something wrong with the bezel where the buttons are located causing the button to be pressed all the time. Check the buttons on the tv and make sure none of them are stuck. #2 is a bad button (switch). Replace the switch or the control board. #3 is a short on the wiring harness going from the switch to the mian board. Maybe it's squished against the frame somewhere. #4 would be a bad main board. You will likely have to take this unit to a service centre to have it looked at.

You need to press the button on the top right of the control ( the TV button) once and that will allow you to control the tv once again. Problem occurs when you accidently push VCR or DVD button which means remote control will try a different frequency to operate a VCR or DVD that isn't there. Hope this helps.
