My tv is linked to an hifi amplifier, as many of yours i suppose. Did someone notice the lag for the audio ouptut between external speakers and internal ones ? And therefore the lag between external audio output and image ?
Is there a way to correct that ?

[edit] Sorry, i just saw that the "Service Menu" chapter of the Samygo wiki solve this problem... I will try

You welcome.
I don't have an external sound system, If you donate me one (like Z5500) than I will dig about your problem
Or you can use free SamyGO Wiki for solution.
PAY CAUTION ABOUT SYSTEM MENU.
I advice you to use Digital Photo cam for take picture after change some settings. You can mistakenly change a setting in this menu and results might be catastrophic.
