At power up, tv scrolls uncontrolably through channels, power light flickers


1. Take remote control far away from tv - 3rd or fourth room. Then switch on tv. If uncontrollable scrolling stops , then cause may be remote button (Ch+ or Ch-) has got dirt inside and its shorting.

2. If taking remote far away doesn't stop scrolling then (Ch+ or Ch-) button on front pannel has shorted. Take a cutter plier and care fully remove button from its circuit board. ( If you know desoldering, it is far better than cutting). If scrolling stops then you can operate channel change with remote.

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.

Hello,

I think one or two buttons on the TV is stuck in and that should be the channel button. Its pressed in that's hy it keeps scrolling.

Disassemble the TV, remove the TV board carefully to get to the channel button, free the stuck button and TV should be okay again.

Note that TV stores a lot of current, so wait a bit before opening the back cover to avoid electric shock.

Good luck.

Toshiba 40rv525r screen says NOT AVAILABLE


I've had the same issue! This is caused by the control panel telling the TV what to do - does it change channels on its own, too, or turn off or on on its own?

What you need to do (if you've not already done it) is lock the control panel out, which you can do under the LOCK menu.

What may help is running the factory reset on page 54.

Sounds like a tact switch problem at the front of the set. The switches are just behind the front panel buttons. Don't replace just one. Replace them all. They are not expensive and will avoid trouble later. If one switch is getting stuck internally, nothing else will work including the remote.

Mitsubishi WS-65611 tv channels cannot stop scrolling


Check to make sure the channel down button is not stuck. If it is not the button is probably defective. Mits has had a lot of problems with the buttons.

Turn tv on, and it scrolls through the channels


Had the same problem, channels would not stop scrolling.
It was as though someone had there finger on the channel up button.
Disconnected the sixth wire, starting with the black wire on the wiring harness for the front buttons, on/off, ch. up/down, vol. up/down, etc.
It works fine, no more unwanted channel surfing!!

Disconnect the front control board and see if that stops the scrolling. If it does, check all of the small tact switches or the remote sensor. If that does not help, you might have a shorted microprocessor IC.
