DirecTV installed a Slimline 5 at our vacation home which is our primary residence with Direct. After the installer left, I found he did a half-assed job and didn't mount the dish level resulting in sat 119 not being available at all. I fixed that today, but have another problem. I am not getting any signal at all on 103(c), even transponders. This occurs on multiple receivers. It continues if I remove all coax to the lnb and reconnect it. The coax from the receiver is connected directly to the dish lnb. I do not use an external multiswitch. All signal strengths from all satellites is above 90. Problem has to be with the lnb unit, right? Is there anything inside that is user serviceable or do I just have to replace the lnb? I know I should have Direct come back out and swap it, but we are here so infrequently that would be a hassle. I just want to make sure that is my only option.
