Run Forest, Run!
I have no problem with your response! Not a problem for me!
I have no doubt that DirecTV knows about the trouble. I also have no hope that they'll fix it after 5 years either! If they wanted it fixed or cared even a little that it be fixed it would be fixed... But it's not fixed. I'll be President of the United States before DirecTV fixes it.
Have you tried blue painters tape over the sensor on the receiver ?
Or, Scotch Tape and color it dark with a charpy or marks a lot ?
I have it on all 3 of my receivers and it keeps out the excessive IR signals from the TV and from the curly que flourescent lights I use and I no longer have this problem.
It is easy to try.
I have suggested this to many and almost all of them have good results.
