I called Cox Communications and the technician told me to disconnect every cable or connection and turn the DVR and T.V. off. Cox ran a diagnostic check to make sure my DVR was reading proper info from their center. It was, and then I reconnected everyhing, cables, HDMI plugs, and finally turned the DVR on. It read Boot, and then, I waited for the time to show. When it did, I turn the T.V. on. It has worked great since then. No problems with sound or picture. Hope this helps someone.

If the TV goes in standby, then it is in protection mode.
Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
Try first leaving the TV power cord unplugged for some times, let say one hour or so.
The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible causes.
1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.
2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , starting the flashing light.
If you are in situation one, then the TV will reset just unplugging power cord for one or two hours,sometimes even minutes.
If you are in situation 2 , then there is an internal fault.
If under warranty contact the manufacturer ringing the number on the user manual

On LCD Pay particular attention at inverter and power board, power board can be inspected looking for bulged or leaking capacitors, then tested with a multimeter. The inverter is more difficult to test , there is need to read voltages, should be done by a tech. Also the LCD controller board can cause same problem
On Plasma, test Sustain (Ysus/Zsus) / Buffer boards , cables to plasma, digital board and power board.
On Rear Projection : check lamp, lamp ballast, power board, and convergence.
On CRT TVs, check ballast , flyback transformer, CRT, Tuner, Convergence.

Do you get any indicator lights at all, if you do, then the 5v standby circuit is working, if you get nothing at all, then the main power supply will be the first palce to look, blown fuse? capacitors?
