Solved! Sony Smart TV makes popping sound when off.

Hello


I have a Sony 55" smart tv on my living room. It is making a popping sound when it is off. It is not typical heat expansion cracking/popping sound. It comes from speakers. First i thought that the power socket was no good. I changed the socket and added a high quality extension cable with multiple fuses and other regulation stuff. The sound comes randomly when tv is off. It doesnt have to come right after i shut the tv down. For example when i turn the tv down and start reading stuff i hear the sound 4 or 5 times in 2 or 3 hours. What might be the reason?

What else is connected to the TV?

Maybe the TV is searching for updates while in standby, usually this can be turned off in the system´s menu

A lot of things are connected, IPTV box, play station, Lan HDD.

Do you think updates can make tv to pop a sound when its off?

disconnect all cables from the TV but the power cable, switch the TV to standby and wait if the TV does this sound again
