I'm trying to troubleshoot poor cable reception on my Allegro Red 37BA.
Your statement is exactly what I see here but I'm getting nowhere fixing my poor signal.
I suspect the problem is the switch and will tear into that next. Sure would be nice to have some guidance.
What I've done is prove excellent signal from RV site by running spare cable direct to a single TV. It's beautiful.
Run that same cable to input of splitter and it is no better than when hooked up in the water compartment.
Switch from cable to OTA and the picture on 2 tv's (I didn't try them all) is adequate.
The antenna switch is wired with a connection for cable, 3 tv's, radio, and antenna. 2 of the tv connections are unused. That leaves cable (presumably input), tv (presumable out to splitter), radio, and antenna (presumably OTA input). So when I try direct connection from RV Site to tv (presumably splitter) I get no signal. I'm next looking to use ohm meter to verify which cable on the switch goes to splitter.
Maybe the electronics on the cable side of the switch is bad. The lack of a wiring diagram is a real headache.
If anyone has insight to the technical side of this cable/OTA switch I'd like to hear about it. I'd really like to know if I could swap from one tv connection to another on that switch. And does the LG Blu-Ray Home Theater & Surround Sound box have anything to do with all this? Mine is unplugged because I don't have a need for it. Turning it on doesn't seem to make a difference but I'd like verification of this.
