I bought an Axion 8" TFT LCD TV with Card Reader a few years ago, Cat. No. 16-3350, and for some unknown reason, channels 9-12 stop playing the audio totally even though the picture was great as usual. No where in the user's guide do I find a troubleshooting advice for this type of problem. A lot of favorite tv shows are on these channels. Do you have any resolution advice for this problem. Thanks in advance. John N. Lawson; jnlawson8@yahoo.com
