Jamiecole2, what type of music do you play during the day? If it is mellow music, he should sleep during the day as well, but they really need a minimum of 10 to 12 hours sleep each night.
If it is at all possible you really need to at the very least move his cage from away from the tv, since it tends to startle the birds especially if you watch any kind of action program.
Do you know for sure that he doesn't sleep when he is covered?
And you really need to cover the cage anyway regardless of whether or not you think that he maybe sleeping. The light of the tv is much brighter than that of a nite lite and harsh for the bird.
Please try and be diligent for your birds sake.
I am really not trying to be rude just concerned.
