Question about Samsung LN40A550 LCD TV
Hi my name is Eric,
I hope I can help you with your issue ,
Do you have a cable box?
First thing i think of is you need to reboot the cable box by unplugging it from AC power, then reconnect it. (then reboot the Tv same way if haven't done that yet either) then its time to try it with AV cables
to make sure the cable box is not bad. using the red/white and yellow cables
then testing with another source like a DVD player, common sense will tell you if its the cable box or the TV.
If you've already done this or don't have a cable box (sorry),
The only thing in the TV that can cause you to lose audio only on TV is the SAP mode.
Hope this helps, if it has solved your issue please click accept
But if you have more questions please respond and I will reply asap
