I agree with wayez, but there are other possibilities If you can get at the mains switch, check the mains wiring looks good and the switch operates with an ohm meter. See if there is a small mains tansformer in this mains wiring part of the circuit. If there is, it is quite likely the primary has burnt out, causing it to short circuit; the thermal trip will have reset which is in this transformer winding. Replacing this transformer is easy but make sure on switch on that its output is not shorted by another fault. Leaving a TV on standby shortens the life of these components. I have had lots of faults reported for TVs only 2 or 3 years old, so not only is your electricity bill more but it may cost you on average, 50£ or more a year extra due to a massive repair bill.
