Thanks for the message. Follow the steps below to perform Power Reset.
1. Turn off the TV.
2. Unplug the power cord of the TV from the electrical outlet.
3. Let the TV remain without power for 60 seconds.
4. Plug the power cord back into the electrical outlet. (If the television is plugged into a power strip or surge protector, 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.)
5. Turn on the TV.
If the issue is still unresolved after performing power reset, 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.
