Hi there,
I see you have been waiting some time for an answer.
There is very little information in your question to help us determine what the problem is.
If this is an electronic device, then first check that it is fully charged, and next try a reset by pressing and holding the power button for up to 20 seconds.
If you need further assistance, please let us know the make and model number of the device, and more details about what the problem is.

Ok, that sounds very like a defective power supply board inside the TV - the power supply board will need to be tested and replaced if confirmed as defective.
