Question about Televison & Video
Do you hear any click sound?
ONE: The protection circuit is shutting the set down when you turn it on - to avoid further damage to the set.
TWO: The reason for the shut down is due to the protection circuit detecting excessive current in one or more sections of the tv.
THREE: The clicking sound is the ON relay getting shut OFF by the protection circuit. The thumping sound in the speakers is from the power supply coming up in voltage a little, and then shutting down.
FOUR: Number one reason for auto shut down in big screens is loss of high voltage. Number two is defective deflection amplifiers (horizontal or vertical amplifiers).
FIVE: These repairs are not something you can do at home; they require the service of a trained tv tech.
A Toshiba of this age is very marginal as to whether it is worth the repair investment. May be better off applying the money towards a new set.
Please don't forget to rate the solution.

A couple of possibilities:
1. While in transit, something must have jarred loose internally;
2. your post "...Nothing else is connected up to the TV..." might be causing a video/audio mute, have you tried connecting an aerial or cable to it?
3. try do a reset. Unplug the unit from the mains for a couple of hours and try again.
If problem persists, please try to determine if there is a sequence to & the number of times the "...green 'timer on' light flashes..."
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.
