TV Speakers work intermittenly

[squeeg22]

So, when I first turn on my TV there is no sound coming from the speakers. After a few minutes or so, the sound begins to intermittenly come from the speakers. Finally, after watching for 10-15 minutes the sound returns to normal, except for the occassional crackle.

Does anyone know what causes this and can it be fixed? I usually use the Audio Out from the back of my TV running into my receiver until the speakers are "warmed-up". BTW, the TV model is a Sony KT-57WP600.

Thanks

The real question is if you have external speakers why would you still use the TV speakers?

Because you don't always want to turn the entire system on, maybe you just want the news on in the background.

I suppose this makes sense if you are trying to do two things at once on the same system...but otherwise I don't see the point

When I set up my parents TV for them I disabled the internal speaker entirely. It's annoying to have to turn down the internal TV speakers whenever you want to listen with the home theater system.
