I have a 19 inch flat screen HD Ready TV that I bought 2 years ago. Just recently all of a sudden two stations have no sound. They have perfect picture, but no sound. I can not figure out why just those two stations do not have sound. the Stations have sound on the other tv's in my house so I know it is some thing that happened within the TV. there is some type of block on sound within the TV for those two stations. How do I unlock the problem

Hi.
If the problem is restricted to two channels only, and the rest of the stations are working, then it can be a faulty tuner device. If you are using an external tuner box, test using a replacement tuner.
If you are using the built in tuner (aerial connected straight to coax socket at the back of TV), then the problem may be the internal tuner.
Before contacting repair or purchasing part, ensure that the problem is not low signal (bad reception). Video and audio digital signals are carried on different channels.
Test the TV performing a channel tuning and resetting to factory settings.
In some case the problem may also be caused by connection used. If for example the sound is carried from a receiver to the TV through RCA cables (red and white), you may have no sound from some digital channel. If the TV uses an external receiver box, test using different kinds of connection.
