SOURCE: Toshiba 26AV502U Won't Pick Up Channels

Hi albertogiler, I am happy to help, you will need to attach a antenna to the tv to pick up OTA over the air signals, depending on your location you may be able to use a set of rabbit ears, I have provided a link to a site that will explain in depth. http://www.antennaweb.org/aw/welcome.aspx
Let me know if this helps and please rate this solution. lone99star

SOURCE: White/Grey screen with non-HD channels

I removed the HDMI cable and connected with component video and rca audio. No more white screen.

Picture quality looks good. I don't know if it's as good as HDMI, but then I don't need to reboot the TV three times to get to teh on-demand menu... Grrrrr....

I am trying to contact Toshiba on this as well. I have seen several reports of this problem on the web.

Sections of the power supply may have gone out, or it detects short circuits in the backlight inverter board or in the power supply itself.
Those are the two areas you need to check. Look fo bad caps with leaking/bulging top fist in the power supply.

To see if the problem is with your remote control, go to the receiver and use the channel up/down buttons on the receiver itself. If you can change your channels with the buttons on the receiver, the batteries in your remote control probably need to be changed.

If you can't change channels from the receiver, turn off the receiver. Then unplug it for at least 15 seconds. Plug the receiver back it and turn it on. Again, try changing channels from the receiver itself.

Tune to a channel, and while programming is playing, try tuning to the missing channel by entering the channel number on the remote control keypad to see if channels change. Do not try to select the channel from a channel list, program guide, or favorites list.

If this approach takes you to the correct channel, you need to adjust your favorites list function. Press the "guide" button on your remote. Look for a button on your remote called "fav" or "list." Press it several times and watch for an indication at the top of the guide that you are moving from "all channels" to a particular favorites list.

If you are locked on one channel only, your Channel Lock feature is likely active. Consult your owner's manual to unlock the rest of your channels. See your owner's manual for information on managing favorite channel lists and locking out channels. Enter your password, if necessary.

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.

Tv turns on and off by itself


I had this happen to me just last night. I noticed that it happened as soon as I turned to a particular digital channel. It would turn on and off quicker than I could change channels. To correct this:
1. Remove the cable input, the coaxial cable, from the TV

2. Turn the TV on

3. Change to a different channel

4. Delete the channel that was giving you problems from the lineup

5. Reconnect coaxial cable and you are ready to enjoy TV again.

dont know if this will work for you but it did for us ! good-day !

I have a Toshiba TV/VCR/DVD combo, remote WC-FN2. I can turn the TV on,change volume but can not change channels. Help! Thanks,


Some tv remotes will do this if the TV is programmed to skip all but one channel (or the last scan for channels had only one active channel - like a tv connected to a set top box (3,4,60)).

See if you can navigate to other channels by typing in a channel number. Also check if the Tuner is the current source of the video signal by pressing the Source or Input button. If you have a menu button on the TV or the remote, try rescanning channels or editing the channel list.

I hope this helps.

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 turns off when you change the channel


sounds like a power fault, prob just weak capacitors if you can change them it would not cost a lot to replace them, when you change channel it draws more power and if its at its limit it will turn off as the capacitors cannot take it. few £'s or $s to get the replacement capacitors, you will probably see the blown capacitors on the power board as the will not have flat tops they will be rounded, change them same for same i.e 16v 330 for same 105c type would be best. it will say this on the capacitor.
