Sometimes you really need to get down and dirty. The basic tests aren't enough. You need the real information. DIRECTV receivers have three built-in tests that can help you understand what is going on inside that sleek black box.
Disclaimer: These tests are designed for ADVANCED users. It's pretty hard to do any permanent damage with them but as with any high-level tests it is possible to get yourself into a pickle, so be careful. If you don't think you'll be comfortable with using these tests, don't do them. Neither DIRECTV nor SolidSignal.com or its associated companies are responsible for any damage or lost data resulting from the use of advanced tests. If you undertake any tests not designed for the regular public you do so at your own risk.
