TV turns on and changes channels on its own

TV turns on by itself and you'll walk into that room  to find it on.  It also changes channels on its own while you're watching and you can't get back to the one you were watching

    Changes channel and will not hold channel. It has also turned on by itself. Turned TV off for 12 hrs. This kept the channel stable for about 30 min.

Keeps changing channel
Check voltage on D12 if below 4.8V then change
Changes channel or volume adjusts by itself
Check S900/1/2 on pcb H1, alternatively this could be due to failure of IC005 (CD4052BCM-FL63) on pcb A

I have a 50" philips magnavox tv that changes channels on it own and turns itself on frequently. What is causing this issue?


Do you live with someone who likes practical jokes; even silly ones?

There are a number of companies that make remotes that can mess with someones TV or other remote devices.
I have a watch, as a gag, that will self program its remote to operate any TV capable of this feature. With this watch, I can change channels, power status and even reset the TV to factory default state.
Next time this happens, look behind you.

Toshiba tv 40rv525u has started to change channels


My TV 40RV525U changing channels, menus itself for few months ( I use antenna).
my son tried to stop the channel scrolling by enter weird number into the channel to stop it scrolling such as 555, 777..
later, it turn on off by itself and unable to hold on a channel
I call Toshiba customer service and they ask money $25 for troubleshooting but I denied since I do not want to waste money and time.

Now, I found how to fix it myself.

In my case, something was wrong with the signal comes from the button control on the left side of the TV.
========================
What I did
========================
unplug the power cord.
Remove back cover.
Look into the motherboard ( biggest green at the center).

First, I disconnect a connector on the motherboard come from the IR board that receive the wireless signal control ( meaning the remote is disable).
I turn on the TV, press on Menu button on the TV side. Menu is still scrolling.

I turn off TV, disconnect power cord and connect the IR connector back to the motherboard.
I then disconnect the nearby connector that comes from the side control buttons.

Turn on the TV by remote, press menu button on the remote to check. The menu stays.

DONE.

I use electric tape to seal off the connector and let it hanging there.
Close the TV back panel

I have been watching TV for 3 nights without menus/channels scrolling.
NO AVAILABLE red message when watching DVD is no longer existed.

Hope this help someone else.

I have a small magnavox HDTV. I unplugged it to watch it in another room. The next day when I moved it back into the living room I turned it on. Every time I try changing the channel it changes the source...


Is it a multi-function remote? If it is, make sure you've punched the TV button before using it. Also, make sure none of the buttons on the remote or the TV have accidentally been pushed down and are stuck.

I have an apex flat screen TV and I use direct TV as my cable provider. I was watching TV and walked out of the room and when I came back the TV said to run the channel auto scan in the TV menu...I did...


unplug the tv and the direct cable box reset the box by plugging both the tv and box back in. MAKE SURE the tv is set on the right input for the box first. if the tv said to do auto scan then you lost the connection from the box either by changing the input that box is connected to if by a cable its usually 3 or 4. if by hdmi or rca cables its an input channel. also make sure not cables are loose try that first before unplugging the tv let me know

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.

TV or Satellite Box Problem?


Do you have a VCR or DVD recorder? If yes, set it to record what you are watching. After a "blackout" rewind the tape and review it. If there is a blackout on the tape, the problem is the sallite box, if not, it is the TV! QED
