Tv has started to change channels on its own from 3 to 33 to 59 to69 and the remote will not work to turn it back to 3. tried unplugging and still does it.
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.

Are you using a cable box or a satellite receiver? They too have format, Zoom, or view mode buttons.. It seems like there's several names for them but they do the same thing. I hope this helps.

Its a backlight problem. Common with this model. Under warranty? If not, then its a service shop repair.
