2018 XLR Nitro 35VL5. The cable in question is the coax cable that comes out of the wall in the garage area below the TV antenna booster wall plate.
I have been experiencing trouble with my antenna/cable TV. I have a cable tester with numbered terminators that can be installed on the cable outlets/inlets and traced/identified by number using the tester. I discovered that I have a faulty splitter and have ordered a replacement from Amazon. The cable I have not been able to trace/identify is the one coming out of the wall in the garage.
Here is the wiring that I have discovered so far for anyone that may own a 35VL5. Hope this helps someone.
1. Satellite input from the outside wet bay goes to the Satellite output on the wall plate located by the living room TV.
2. Cable input from the wet bay goes to the garage TV antenna booster wall plate "Cable input" located on the circuit board behind wall plate.
3. TV antenna goes to the garage TV antenna booster wall plate "Antenna input" located on the circuit board behind wall plate.
4. TV antenna booster wall plate "Set 1 output" located on the circuit board behind the wall plate directly feeds the connector for Cable/Antenna on the TV antenna booster wall plate.
5. TV antenna booster wall plate auxiliary/satellite? connector is a feed through connector on the wall plate and is not connected.
6. TV antenna booster wall plate "Set 2 output" located on circuit board behind wall plate goes to the 4 way splitter "Input" located behind the XLR control panel in the living room entryway cabinet.
7. The 4 way splitter located behind the XLR control panel in the living room entryway cabinet "Outputs" feed the Cable/Antenna wall plates for the Living room TV, Bedroom TV, Loft TV, and Outside TV.
