Sony TV KDL- 46EX723 switches itself on and off at random intervals.

my Sony KDL- 46EX723 (8 year old) switches itself on and off at random intervals.

I checked setting such as Eco/standby/timer etc and also my firmware is up to date.

I changed battery on remote controller and cleaned the TV by removing back cover.

but still the TV is clicking and rebooting automatically.

could this be any hardware issue? if so it is a PCB ? can you please advise.

Have you tried a different electrical main? Also, did you try to disconnect the TV from the mains for a few minutes or factory reset the TV? Are any devices connected to the TV when this happens?
