View timer keeps blinking..tv wont turn on.nobody set view timer..is there a reset button? tried to unplug but no luck


Mute + 1 + 8 + 2 + Power.

Your TV set should now say “Loading Factory”.

Browse down to “Option” then press Enter (or the right cursor button).

NOTE: The Mute+1+8+2 buttons need to be pressed down consecutively and fairly quickly. If your TV does not enter the service menu after using this combination, you can substitute MENU instead of MUTE. This seems to work for some sets. Also, the right cursor arrow also acts as the ENTER button, so try it if you’re having difficulty with the ENTER button.

To exit the service menu, hit press the EXIT button or just turn off your TV (remember not to turn on your TV immediately afterward!)

Toshiba Regza 32C3000A tv sound keeps droping out, the mute button when pressed on and then off brings it back on. seems as if the tv is auto muting itself?


Could be a contact piece of the MUTE button from your remote that is causing it.
Go out and Big Lots or Radio Shack to get a cheap universal remote control(big lots would be between $5-$10) Pick up the code for it,and when the tv happens again,your the OLD remote MUTE button to turn it back on and then put away this remote control and use the new universal remote control.
However,if the problem is coming from the manual MUTE button on the TV,you need a repair tech, to fix it!

28" Toshiba TV has no audio when TV is turned on. the speakers are fine as you can hear a video tape. need help


Check if the speakers are switched on in your Menu:

Press the AUDIO button on the Remote Control or the Menu button on the TV set to display the AUDIO menu. Repeatedly press the AUDIO button on the remote or the ADV button on the TV set until SPEAKERS is displayed in magenta

Press the + or - button to call up the SPEAKERS ON/OFF mode on screen display. Each time you press the button ON or OFF mode alternate. Make sure is is switched to on.

Also there is a switch on the back of the TV to control which speakers you use, it says MAIN SPEAKER EXT-INT make sure this is set to INT.

If this doesn't work you'll have to contact Toshiba service.

Hope that helps..........
