My installation is about 5 months old going on 6. Dish contractor installed a Hopper w/sling, Super Joey and a Joey, all new wiring and a new dish (I held out and was still using my 322 boxes with old series 1 tivos till I could not stand only recording 2 shows at a time anymore). Everything was working ok till about a month and a half ago when I started getting recordings which were cut off with loss of signal and occasionally getting 503 loss of signal errors watching live tv. I have run a check switch and it tests ok, have done a power cycle of hopper and SJ then run test switch again and it is still ok however still have issues. I was going over the diagram from page 12 of the hopperjoeysystem_jobaid.pdf file and comparing to my cabling and everything looks spot on, connectors are tight no corrosion and center leg is long to reach connector inside devices. The only difference I noticed is on the diagram it shows the Integrator should be grounded to the Solo Node, mine is not could this be causing all of my issues?
