Please help me. I have had 4 HR20's and had techs come out 4 times. The problem is still there and very hard to detect. Directv escelated the problem but I am not sure how it will get fixed as the local installer had no clue what was wrong. Here is the problem: 1. I have 3 receivers, 2 HR20-700 and 1 old Samsung HD 2. Both the Sammy and 1 of the HR20-700 work great with signals all in the 90's 3. The one receiver is always having problems and I am on my 4th one. What happens is the signal on one of the tuners goes out like once a day and a simple reset fixes the problem. This problem did not occur until they put up a Slimline and took down my AT9 because the 103 went bad. 4. They ran dummy wires and ran the wire from where the good receivers were and the problem was still there 5. the hard part is that this only happens once a day and a reboot fixes it. So when they come everything is in the 90s. Something must not be grounded or is shorting out. Its very wierd. Maybe this is why the 103 went bad on all boxes before. Bottom line is that no one can figure it out. I keep blew the tuner in 3 receivers with this problem so keep putting in a new receiver makes the problem worse. When I switch signal 1 with signal 2, signal 1 is still out, so I doubt its the feed. could it be bad grounding, could it be the multiswitch. No one knows.
