Have you tried changing the input channel of the tv some tvs dont give any indication that theres no signal. If that doesn't work try plugging in a device that gives video output that you know works.

If the previous solution didn't work, which means it's not a no signal on input, fry disconnecting the TV from power completely for about 10 minutes. If there is an issue with one of the capacitors in the TV, it will discharge in that time.
