Be sure your remote hasn't got a button stuck down which is changing channels. If not, take the batteries out of the remote. If this stops the channel changing there is probably some conductve material stuck across the circuit board
inside the remote. If this is the case you have to check inside the remote by openning it up.

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.

What's your problem?Won't stop changing channels


Hello,

there is every possibility that the channel (ch - and ch +) button on the TV is stuck. This can make the TV channels change by itself. This also applies to the remote control (if any).

Turn off the TV, use your thumb to flip through the channel (ch - and ch +) button on the TV. This will free the stuck button. Also, check the channel (ch - and ch +) buttons on the remove and make sure it is also not stuck in.

If the above doesn't solve the problem, then it means fault is from the control board inside the TV. It maybe defective or needs servicing.

The board controls the buttons on the TV and it can be found on the position of the channel (ch - and ch +) inside the TV.

Note that TV stores a lot of current. So if you want to disassemble the TV to check the board allow the current to discharge by remove the TV plug from the wall and wait for about 1 hour before attempting to disassemble the TV.

Let me know if you need more assistance...

Regards.

My 32" G.E. television can


I have had similar experiences. I have a VCR sitting near the television. I found that if I keep the VCR turned on then the TV stops changing channels by itself. If the VCR is turned off, then it starts again. Weird, but it worked for some reason.

AOC Plasma TV turns on by itself and changes channels non stop.


I have an AOC 32" LCD HDTV and it turns on by itself as well. Tuning is done via my cable box, so the tv is set on HDMI and I don't have the channel changing issue. I as well am trying to figure it out. The only thing I could suggest is perhaps the remote batteries are low and triggering on it's own. Try changing the batteries, or ensure that the remove it in a drawer or other room so that triggering the unit is impossible. Hope that helps.
