Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

When I turn my TV on, it comes on and says 'no signal' then after about 5 seconds, automatically switches its self off... any idea why?


Most sets will shut down very fast if no signal at all.

If you can before it shuts off try to change input to one of the rear audio video inputs that has something connected to it and turned on.

Failing there and if using a box of some type for signal--unplug it and the set both for a while---plug back both and let each try to boot up.

A total loss of signal or a glitch with the set or a box can confuse the TV set's Microprocessor.

PUT IN A NEW LAMP BUT NEED TO KNOW HOW TO RESET TIMER. THE WORDS STAY ON THE SCREEN FOR 1 MINUTE.


Turn the TV on, and once the timer leaves the screen (after 1 minute as you say) you do the following.

Hold both the "Volume Down" button on the TV it's self and the "Split" button on the remote for at least 5 seconds. That should reset the timer.

Toshiba TV fails to recognize HDMI input


If the tv does all those symptoms but after some seconds the tv works and stays doing the job. THen the tv has a slow microprocessor to recognice the different resolutions or video inputs.

But if the tv cannot do anything and stay aout of signal forever. send the tv to the waranty. (no waranty? you have to use the component input instead to have digital signal reproduced

TV will not stay on


I would just return it and get another one, if they fuss about it, then ask for a discount on a new boxed model.
