The cockpit RCA television was not working. No “standby” red light and, of course, said light didn’t turn blue with the remote. Pushing the “standby” button on the side of the unit had no effect. It was either very dead, or not getting power.
Our system has the HDMI splitter under the TV above the fireplace which takes HDMI inputs and distribute them amongst the various TV’s. This is done via CAT-6 cable and each TV has a little jack to convert said CAT-6 back to HDMI. These jacks are powered by a power supply into the outlet behind the TV. They have a little LED. This was on, telling me there was power to the outlet.
The front TV (by law in many states) is disabled with the ignition on. So are the awnings and the slides. (Don’t want little Johnny to go: “What does this button do?” and have him deploy the 20′ slide as you are doing 65mph inches from a semi). Since the awnings and the slides were working, I knew this circuitry was in order and that power SHOULD be going to the TV. (Note: I have since installed an override for the ignition lockout system).
So the next step was to take it down and look behind it. Here is where I’ll save you some work/headache. On my 38A the TV is mounted on a metal bracket which is screwed into the back of the wood face frame between the two overhead cabinets. If you look in the cabinets you’ll see two pairs of screws on the panel facing the TV. The forward (as in the direction you are facing when sitting in the driver’s seat) of each pair is about 1-1/2″ and connects the center and outer cabinet. The rearward (again, as in towards the BACK of the bus) of each pair is 3″ and goes through the panels into the side of the wood face frame into which the TV bracket is mounted. Remove these 4 screws (2 on the left, 2 on the right). Now remove the bull nose trim (half round plastic trim) on the two panels facing the interior as they will interfere with the face frame. It is strong, there is no glue and they come out nicely. Now you can grab the TV and pull it about an inch towards you and then down, and away.
In a very anti climactic but lucky break it turns out that the ignition lockout gizmo which the TV plugs in to and which itself plugs into the outlet had unplugged itself. Plugged it back in and viola….. power to the TV.
Reverse the process to re-assemble.
Update……11/17 So the darn ignition enabled power box that the TV plugs in to and in turn plugs into the outlet is heavy, and keeps working it’s way out of the outlet when driving resulting in me either having to go in there, again, or not being able to use the TV. So, I went in there to screw a strap or something on there to keep it in the outlet when I decided that I was adult enough not to turn on the TV while driving and I just plugged the darn thing into the outlet directly and shoved the box aside. There, take that nanny state. Problem solved.
