Fix for Samsung LCD audio delay

Thanks to a thread on Home Theatre Forum, I was FINALLY able to fix that irritating delay on my Samsung LA46a550 LCD TV.

When the tv is turned on and connected to an external sound system, there is a split second delay between the sound coming from the tv’s builtin speakers and the external sound system’s speakers causing an echo effect. So far Samsung’s reply was to mute the tv’s speakers when using an external sound system…

Basically, you can change this setting in the Service menu which also allows you to do lots of other interesting stuff.

WARNING: The User Interface is horrible, and the chances of accidentally changing a setting is high so use at your own risk. I’ve already had to factory reset my tv twice since I’ve started playing with the menu.

Anyway you can trigger the service menu by turning off the tv and pressing Info, Menu, Mute, power on buttons in sequential order. The tv should turn on with the new Service menu options.

I got a different set of options from the thread on my TV which mentioned that there should be a “Audio” submenu in the Service menu with an Audio delay option.

On my tv, you need to go to the “Advanced” menu and do so by going to the Advance tab which will unhide all the advanced options. Im not sure if theres a delay or a specific combination of buttons to press but I’ve managed to get into that menu via pressing lots of buttons on the remote.

Then go to the “Sound” menu and look for an Audio delay. Mine was set to 950 and changing it to 10 fixed the audio delay for me.
