My dish has been in place for over 15 years. Now I'm getting "Searching for Satellite Signal" on half of the channels, the rest are alright. The transponders show that all of the even numbered transponders (2, 4, 6, 8, 10, etc.) don't see any signal, while the odd numbered ones show a signal strength of 88 or better. Is the problem the receiver?
Do you know if it's a "Single Wire Multiswitch (SWM)" dish?
This is typically caused by a loose, moist or corroded coax connection at your dish, ground block, or multiswitch. If you can easily access those, try loosening an re-tightening them. Otherwise best to call for a service visit. It's free if you have DirecTV's Equipment Protection Plan. Otherwise ~$50.
