Question about the Audio setup - 2000 Itasca Sunflyer

I would appreciate very much if someone can shed some light for the following problem on a 2000 Itasca Sunflyer 34 footer.

Problem:
The TV sound is very weak, almost not noticeable. I used the same stereo jack (behind the TV) on my iPhone as well. I can hear the music but it is not any louder; pretty much useless low audio level.

We have 4 speakers that look like they were made by Bose (but they are not), a Sony Head Unit (Car stereo), and a new Flat panel TV.
Once the Switch is flipped to the RADIO (I will attach the photo), the sound comes nice and clear. It is controlled from the Sony Head Unit.

However, once the switch is flipped back to the TV position, we get the same low volume sound. The volume on the TV is maxed out all the way...

Any ideas? Is there a hidden amplifier that's suppose to boost the TV out volume?

Here is the photo of the TV/Stereo switch I'm referring to.
Thank you for your input...

The old TV had a preamp built in and new tv's don't you will need a preamp to drive the amp.

Any Ideas what kind of preamp/amp would work? 12v or 110? Are there any RV specific products available?
Thanks!

I think that's only a preamp. Also something you need to be aware of is that the audio out on most of the current TV's is fixed level. That means if you add an amp you will not be able to control the volume with the TV remote. You might want to check your tv to see if the output can be set to variable. These days very few tv's do.

You can download all the schematics for your unit from the Winnebago website, which will aid in your troubleshooting.

You unit should have a remote amp located somewhere in the front cab. On my 2003 Adventurer it was located on the passenger sidewall under the dash. The variable outputs of the tv and radio were wired to this amp. A switch on the dash controlled the dc power to the amp (chassis or coach battery). The little switch you pointed to switches the amps input from tv to radio.

Winny wired their older tv's to provide a variable output. Your new tv most likely is providing a line-level output which is non-variable.

Sometimes this output can be changed to variable thru the tv's menu, but depends on the tv.

One fix would be this:

MCM Custom Audio Line Level Volume Control with IR Remote | 50-8394 (508394) | MCM Custom Audio

and adds another remote.

Another route might be using an input on your dash radio if it has a remote.

Of course, this assumes your tv output is now connected to the original amp.

Thanks for your ideas. I have found the wiring blueprints for this year's model, however I can't find the one exactly like the one I'm working on. Looks like over the years some components were moved around.

The TV I have has the headphones out jack, so I believe that is variable output. I'm afraid the amp (still need to find it) is shot. There is also a passive subwoofer under the pullout couch.

Will report back...appreciate everyone's input and suggestions!
