There is no text on screen when those buttons are pressed after the standby mode. After the last button i.e. Power button is pressed, the TV is turned on.

I hope I get your instructions correctly.

Maybe it is different for Asia/Pacific TV (="LA") compared to US (="LN") and Europe (="LE"). I will do some quick research.

According to the service manual found here


it is POWER OFF -> INFO -> MENU -> MUTE -> POWER ON.

If that does not work then a different reset technique needs to be tried, but I am not sure it will work on these models.

Hi Tom66,

It seems to work.

I pressed INFO->MENU->MUTE->POWER ON and some texts appeared. I selected RESET and the intermittent audio seemed to be gone.

I will monitor for a few days.

Thank you Tom66 for your guidance and patience.

Glad to hear, let us know if it's a permanent fix.

The intermittent audio is back.

After I switched off for about 8 hrs, the problem returned when I switch on the TV. Seemed like the factory reset only worked for a while.

Could it be the caps as the power is discharged after 8 hrs?

Go back into the service menu and check what the READY is set to. It will be hidden in one of the sub menus.

Re: Samsung TV Model LA26R71BA

The Ready from Option Table(Service) is set to ON. It cannot be turned OFF.

The TV still has intermittent no audio. Where else should I check?

Re: Samsung TV Model LA26R71BA

So, out of interest, if you repeat the reset procedure, do you get another ~8hrs? Or perhaps that was just a coincidence?

Re: Samsung TV Model LA26R71BA

Hi Tom,

The 8 hrs was the time I left it overnight. I wouldn't know exactly how long it takes to revert back to the intermittent audio problem although.
