DISH Network DVR-625 DTV - AUDIO PROBLEM ON LOCAL CHANNELS ONLY

Bypass any connections, such as running the composite cables or coax through VCR. Hook up from the box straight to the tv.

I am probably stating the obvious here but here it goes:
If the 625 is connected to the tv using coax directly try using the RCA jacks to connect directly to the tv. If the 625 goes through a peripheral first, eliminate that peripheral and conect directly to the tv.If the problem exists with different media connections still at the same tv you can remove the coax off of the TV1(3-4) output on the back of the 625 and attach it to the TV2(CH60-73) output.You would then change your tv channel from 3 or 4 to ch 60air or 73 cable(which will be the same channel that TV2 is normally on in the remote room without the 625) Once you are on the right channel you will be able to tune TV1 to your local channel using the TV2 remote. If the audio is good here it eliminates the TV coax input on the TV1 and the coax cable connecting it as the source of the problem. You will have already eliminated any other inputs on the same tv as being faulty by using the other connecting media leaving you with the internal components of the receiver as being faulty. In this situation I know of no recourse except the obvious.
