A/V mystery - partly solved

Previous owner upgraded TV to a Panasonic LCD. Unfortunately, coach came with no manual or remote for TV. I assume the model number is on a plate on the back but I haven't gotten back there yet, have no idea how the TV is mounted.

Coach came with the Bose Lifestyle 30 system. Have the manual and remotes, but the system is dead.

First thing I would like to do is get to the back of the TV, get the model. If I have this I can probably download the manual, would let me identify the inputs and outputs. Would also be able to go to Logitech and program my current remote with the Panasonic commands. Unfortunately, don't have anywhere near the proficiency of many of the forum members. I need to remove the panel that goes about halfway down the the TV, is behind the TV, goes from drivers side of coach completely across coach to passenger side. This is shown in one of the attached pictures. It appears this panel is secured with six screws into the ceiling. It also rests on pillars at driver side and passenger side. These are shown in two of the attached pictures. If I remove the six ceiling screws, and the three screws in the two pillars, will this panel be released? Will I create a gotcha and not be able to put Humpty back together again?

Was able to get my camera in the small compartment beside the TV, took a picture and found a wall wart not plugged in. This may be at least one of the problems for the Bose. Can't reach it and can't see any AC outlet nearby, but if/when I get the above described panel off, may be able to make progress.

Thanks for any reassurances or experience here.

So, how long have you owned the coach?  Has this condition been there since you purchased the coach?  All power is working as it should in the "Inverter Circuit" outlets/appliances?  This is the circuit that provides power to the TV (120VAC).

Hi Peter
We have owned the coach since May. Problem has been present since then, other issues have been higher priority. All power is working as it should.
I should have said originally, TV has power. I get OTA signal, video is fine, no audio on OTA. Found an HDMI cable end unattached, connected a Western Digital media player, video and audio both fine through the TV display and speakers but nothing through the Bose. I'm guessing the TV audio out is probably connected to the Bose and prevents the OTA TV  signal from providing audio through the TV speakers. Not sure why this wouldn't also prevent audio from the media player but guess the HDMI connection makes a difference.

Not knowing how your LCD replacement TV was installed, perhaps if you can look up and behind the LCD set, you might be able to see the data-plate using a mechanics mirror? When I did my upgrade I installed a mount that would allow the set to be extended/swiveled-out for hook-ups and R&R. As for the Bose, the option I used when my display faded to extinction was a remanufactured exchange. If you're interested you might contact jessemcclendon@yahoo.com.

The small black ac power pack is the power supply for the Bose lifestyle 30. When my Bose system is off I have no sound from the dash radio.  The remote to control my Bose 30 system that came with my rig is a systemlink RCA.I have to push the TV button to turn the power on, the 5 button to turn on the Bose, and the power button to turn everthing. off.Gam

Mike,
I can't help much in regards to removing the TV or the Bose system, but I would suggest that when you do figure out the model number that you order a new original remote for the TV.  There are usually many necessary functions and setup items that the universal isn't likely to cover.  We damaged the remote on our new S&B TV when it was only months old and purchased a new one on line at a very reasonable price.  I think this was the same website (for Panasonic TVs):

From your picture it appears that the trim piece at the top of the TV extends down about an inch covering the top of the TV.  Removing those screws should allow the TV to lean forward and allow you to lift it out.

I was thinking the same as Spoiled. Looks obvious, so I might assume that removing that trim piece was your first move. When I swapped out the CRT for a flat panel, I had a heckuva time trying to mount it. Since the TV was just a tiny bit larger than the cabinet opening, I installed an articulating arm mount to the center back of the TV, and have a heavy bungeee pulling the TV firmly against the rubber seal around the opening ( I added this myself to eliminate squeaks and rattles ). When you look at the installation, it seems there is no way to get behind the TV. All that is needed is to get a fingernail under the edge on any side and pull enough to reach behind and unhook the bungee. Bingo...full access. If the prior owner of your rig did a similar custom install, this explanation might help you with the puzzle. Good Luck!!

Well Mike, can't help you with how to remove the TV, but looks like it will have to come out. I replaced my old CRT TV with an LED, and a new DVD player, as far as the Bose goes in my 1999 their are no USB connections on it all of them are RCA or coax. The plug you are looking at may be the power source for the IR sensor receiver for your remotes. As O/P said you may need to order an OEM remote for the TV, your Bose should have some type of remote signal reciever as well. Once you get the TV out there is a big bird nest of wire and cables behind it, but once you can see the back of the componets it helps figure it out. Another hint is set the TV up where you can operate it and make sure everything works before you put the TV back. One of these days I'm going to replace my 1998 vintage Bose with a new one to help the connectivity issues. Good luck.

Mike, if you haven't already ...... check the Bose power supply brick.    On my '99 it was plugged into a surge suppressor and then into an outlet located behind some paneling in the front right corner of the front overhead.  The weight of the whole assemble caused it to fall away from the outlet.  I used wire wraps to secure all the various surge suppressors around the coach.

The mystery is partly solved. I used the feature set and specifications and dug through Panasonic's list of manuals until I found a match. Downloaded the manual from Panasonic and downloaded the command set from Logitech to my 880 remote. It actually works, have all the commands. Still don't have audio when I'm not using hdmi, but haven't had time to rtfm, hope the answer is in the manual. (I was wrong about the lcd, it's actually a plasma from around 2003.)

Chad and Judy - can't get a mechanic's mirror where it needs to go. I've managed to get my arm partly back there from the side and taken numerous pictures. Haven't been able to get anything useful. When I do get back there will probably need to contact your guy for a refurb music center.

GAM - the power pack is still behind the TV. Pulled the Bose music center out, it really looks dead. Fortunately, the dash radio and Bose are separate on this coach.

John - so far it looks like I have all the commands per the manual.

Spoiled and Bofzwell - when I saw your post it dawned on me that you must be right, that last piece of trim would do it. Unfortunately, that last piece of trim gave me about a 1/4" wiggle at each corner. Pushing and prodding from front, back, sides, top and bottom didn't help. Makes no sense because the way it wiggles indicates it is mounted at the center back, pretty much normally.

bbeane - After much messing back behind the TV, you're clearly right. The TV has to come out before I can make sense of the mess back there.

Steve - I thought the TV would tilt forward and lift out too, typical mounting bracket. Didn't work. When the TV does come down I'll remember to have a helper with a camera.

I tried the cabinet disassembly but the custom cabinet work creates a problem. The small cabinet to the right of the TV has a shelf installed. Secured on the right side with velcro, but on the left it's secured with a screw from inside the TV cabinet. Catch 22. The interior of the cabinet on the left has been reconstructed with nails and caulk, as well as the usual screws. It's so small that even if I rip out the interior, won't have much access.

I've tried to find an inspection camera for rent locally but no luck. The mobile rv guy who does some work for me has one, so will put this off until I need him for other things.

Dave - the tie wraps sound like a good idea. When I finally get behind the TV.

Now, on to the next crisis. Do they ever end?

Thanks to all.
For now, moving on to the next crisis.
