SOURCE: TV will not power on
There is not an internal reset for this. You would need to check what voltages you are getting from the secondary side of the power supply, this would then indicate if the problem is with the main board not starting up the system or if the power supply has a fault. If you have a multimeter then you can carefully check for 24v 5v & 12v supplies. If you are not getting any voltages then the primary side of the power supply may be at fault. The first thing to check would be the fuse at the incoming mains supply on the power board, if this has blown then suspect one of the senmi-conductors & check to see if any of the capacitors are swoolen if so replace them.

SOURCE: I have an LG LCD
This is a real odd problem. If these are the only channels this occurs on, I would make sure that the set is not in SAP audio mode. This is switchable through it's on screen audio menu. If you have other sets in the house that you can also receive these channels, see if they have sound. If not, it has got to be a cable company issue. If they do, I would check with LG to see if they have a software upgrade that addresses the problem. Their customer service number is 1800-243-0000.
Most manufactures are pretty tight with their software so they want to deal with the customer one on one.
I hope this helps,

First you have not indicated the brand or model but that aside the issue appears to be a bad micro switch or the keyboard with the controls on this set, I would suspect the source or TV video button first, not the plastic button itself but the tiny switch it activates, that is bad---have someone get at that and disable or remove that and the set should again function in a normal way.
The micro switches are momentary and should only operate when pressed, the problem is they fail, and with no one pressing the switch activates on its own.
