Check the remote control for its infra-red emission. Check it with fresh batteries. Check by pressing all the buttons on it; and see whether all of it generates infrared signal while pressing. If it is found OK, check and replace the infrared sensor inside the TV. If you wish to get some details; check the site linked here. It has details about how to check a remote control; by one among the post. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ If the remote control is found OK; check and replace the infra-red sensor inside the TV. Contact any service technician.

SOURCE: TV Volume turns down by itself - Philips 29PT8319 Matchline 27"

Most likely the volume down button on the front of the TV or the switch that it activates is sticking. Should be an easy fix otherwise.

SOURCE: Toshiba TV Remote Control not working

I have been seeing a lot of Toshiba remote "eyes" (the infra-red receiver inside the TV) fail recently. If several known good remotes cannot control the TV then the IR receiver will have to be replaced. If you have no experience soldering and unsoldering PC boards then have a qualified tech handle it for you.

I did this the other day and I think it was 1000 that worked with my RCA universal remote. Once I found the code, it was smooth sailing.

My LG TV red light won't turn on. although the plug fuse and the remote OK


Try manually pressing the power/standby button on the tv (side or bottom) the red light should appear, most modern tv's will turn on simply by pressing the channel up or down on the tv itself.. But unfortunately in most cases, this seems to be an internal surge and needs a professional to inspect..

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 am trying to set up dish network on this tv i can not get the channel to change to 73 only 70 and 76 i have no remote control for this tv just using whats on the tv


Hello. If this has not yet been resolved, I have some simple steps for you that will help you out.
First off, it sounds like the remote needs to be programmed, and since I do not know the particular DISH remote you have, here are the steps for a power scan, which will scan the TV for the correct code.
1. Hold down the Clear TV button until all lights at the top of the remote light up
2. Press the red TV POWER button
3. Press and release the up arrow on the remote about once a second until the tv turns off.
4. When it turns off, press the # (Pound) button
5. Try powering the tv on/off, and try the volume. If one or more of these functions do not work, start over at step 1 again.

Then once you are on 73, that picture will work. You can also try the alternate channels, which are 22 and 21. That may also give you a picture. I hope this helps!

Lost remote and now cannot move to any channel except 3 and 4


If you have a vcr, set it on channel 3 or 4 to match the tv, hook it to your set and use it as your channel changer until you can come up with a better solution.

I wanna put the tv on input but dont have a remote ....and it doesnt have an input button on the tv


On some of the crt televisions you could channel down 5,4,3,2 and then they would go into the line input that way.. Other wise you can get a universal remote and get in.. Im not for sure on the older Toshibas but its worth a try!

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.

Input channel

You keep pressing the TV/VIDEO button to switch between input modes.

Here is your manual in PDF: http://www.tacp.toshiba.com/tacpassets-images/models/27a34/docs/27a34_om_e.pdf

(See page 24 of the manual).
