I have a Mitsubishi SR-HD5 Satellite HD receiver. It is failing! It cannot see Sat 109, transponder #2 at all. Many others do not have signal strengths over 60 or 70. I believe that the guide is transmitted on 109 #2, so without that, the entire Sat receiver section is not working. I know, you're thinking that my dish is defective, its alignment is off, or line of sight to the satellite is obstructed. To that end, I bought another new dish (wanted two anyway). I sat it up and it works fine with my second receiver. I cabled over to the new dish from the HD5 receiver and got exactly the same symptoms as before. I have isolated my problem to the HD5 receiver. Now, it's only about 20 months old. I'd like to see about a repair or exchange program. Problem is that none of the authorized service centers know anything about HD/DirectTV receivers. I tried Mits directly . . . no luck there, either. Their website doesn't seem to admit to their existance. So, my question is: Do any of you have any suggestions on getting my SR-HD5 receiver fixed or exchanged? I hate to throw away a $1,000 unit without trying.
