Around 14 plus channels do not have volume, voice, sound, etc while the other channels do. The picture is great on all channels but no volume on others. Some of the channels are 8, 14, 26, 50, 63, etc. A total of 14 or more which has no sound. Could you please tell me why and if it would cost alot to have it fix as I'm on a $800 fixed income monthly. Thank you in advance for all your help.
