Hi

Software is up to date on my tv

Recently and randomly, some times it does sometimes it doesnt, when I switch the tv on (or after a few minutes) the sound goes & then it turns itself off!. 

It only takes about a minute before coming back on but during that time i get the following on the screen.....

SONY. Then for about 30 secs the coloured, moving circles/symbols, then ANDROID and then back on and all normal!!

Have others had this problem? Is this a Sony issue that will be sorted at next software update?

Have unplugged tv for a number of minutes. That has not worked. reluctant do do full reset

Thanks anyone for your response
