My tv [vizio vf550m] won't respond to a remote.


Vizio is famous for having main board issues. If you have replaced the IR board the only two other items it could be is a broken wire from the IR to main or the main board has an issue. Nothing else can stop the remote from working provided the remote is working properly.

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.

Westinghouse tv turns off with rmote but cannot be turned on unless button on tv itself is used


How old are the batteries in the remotes? The on/off signal from the remote is the same. There is some lattitude in the IR reciever module for what it accepts. Low battereis may be shifting the signal's frequency or light intensity enough for it to not be recognized.

If sunlight is failing on the sensor or the remote's IR emitter, that can cause interference. Other IR devices can also interfere with the IR signal such as a "Remote Extender" being used for something else.

It may sound odd, but if your remote was working one day and not the next- was the room rearranged? If so, look around for possible sources of interference blocking the beam from the remote, or shining or reflecting light onto the IR reciever module in the set.

Very good TV. Since this is LCD there's not much that goes wrong with them except their internal power source. You will have to get it serviced. It is not something you can do without the expertise.

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.

Tv will not respond to remote


You may need to reset the TV. Try unplugging the AC cord it for 15 minutes and then reconnect it. Also, while you wait for that... grab a digital camera, point the remote at the camera so that you can see the dark glossy plastic end or IR emitter. Your eyes can't see the inferred, but the camera can... just look at your cameras screen and you will see the emitter light up when you hit a button. Try a few remotes just to verify your test if you don't see anything. Finally, if the remote is lighting up and the TV power cycle didn't get it... you may need to replace the IR receiver pcb within the TV bezel. Sorry, I can't find a PN for you.
