Alright, its kind of ironic that the first question I have to post on this forum is on electronics but, regardless, I'm perplexed.

My brother recently moved back in with my parents and had free reign of the electronics for about four months before I came back to visit for a while--which means I'm left with trying to /fix/ everything. This means, completely reformatting and restarting computers and fixing whatever he has done to tvs.

I've got the computers, but the tv's are not something I understand.

My parents have Direct TV, my brother attempted to connect a PS2 to it, and in the process retained pictures, but killed the sound.

I've unhooked everything, and replaced all the cables into their presumable right places (red goes in the red slot etc.) and it looks like it should be working---it seems to match the other tvs.

However, the tv claims it can't find the 'stereo' sound system (only the mono) and there is no sound. If you turn the TV itself onto another channel you actually get to hear fuzzy sound of a random channel but when its on the direct tv box, nothing.

So, anyone have any idea of what my brother did to it? The sound works on the tv technically, just not on anything my parents would want to watch.
