What is the model number off the back of the set?
When did this problem occur?
Additionally, what is connected to the TV for devices (Cable box, DVD, etc.), and do you have no sound regardless of which you're trying to watch?
The tvs up stairs work fine they are also hooked to Directv. The playstation3 works fine its just the sound on the tv it self
What I'm asking is does the PS3 have sound on this TV currently?
Okay, if the PS3 does have sound on this TV, but Direct TV does not, then the problem is not with the TV.
First, make sure the Volume is turned up on BOTH the Direct TV box AND the TV. Each has its own independent volume control and if one or the other is turned down, then you will have no sound.
Beyond this, please reset the system by following the steps below:
Please shut the TV and Direct TV box down. Unplug the Direct TV box from AC power for minutes. During this time, disconnect and reconnect the HDMI cable on both ends, making sure it is secure. Then plug the cable box back in, turn on and let it reboot. Once it's rebooted, then turn on the TV and attempt to watch a program.
The sound should be back on at this point.

I'm confused, you said the TV lost sound. If the Direct TV and the PS3 both have sound from the TV, then how is the sound lost?
Does each TV have it's own Direct TV converter box?
Then please follow my instructions and reboot the Direct TV box connected to THIS TV.
