Thanks for the message. Is the TV plugged into a power strip or surge protector? If yes, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television. If you are not using a power strip or a surge protector, plug the power cord of the TV to another electrical outlet. If the issue still persists, that may be an indication that the TV needs service. You may refer to this link to locate the nearest Sony authorized service center in your area.
