Title: Javalena/Audit CRT monitor replacement
Post by: DayDreamer on March 07, 2020, 01:59:40 pm
Our 1997 U320 has the original Javalena/Audit CRT monitor which is not working.  It was working when I bought the coach, but a few weeks later it stopped working.  I watched an old video by Gregory Jones who replaced his with a small LCD monitor with an 800x600 6 inch display and plan so do something similar.  Also read several old posts. 

Anyone done this recently?  If so, where did you source the monitor.  Appears to need two inputs in order to allow switching between the Audit and back up camera. 

Will probably also replace the backup camera too since the current one is likely original and can now get much higher resolution ones.  For folks that have multiple cameras, where do you install additional ones?

The previous owner of my coach removed the non-working Javalina and installed a rear camera and two side cameras. He had it done at FOT.

I installed a SeeLevel system for the tanks.

There are a bunch of threads, here is one

Our previous owner replaced the monitor with a 5-inch flat-panel monitor that connected to the same video cable (from the Javelina system) that had fed the old CRT monitor. The dash selection switches still function as they did originally. That flat-panel monitor finally failed and I replaced it with a Pyle PLHRQD7B 7-inch monitor (from Amazon I believe). I've been quite happy with it.

Is the 7" in the dash similar to the original or do you have it mounted externally?

I carefully enlarged the hole where the old monitor was located and mounted it in/on the dash in the same location. I think I could have squeezed a 9-inch Pyle monitor into the available area but decided not to take that chance.

Nice installation David!
Also anyone removing the original system save the remotely mounted power supply.
If it wasn't the reason that system failed I'm sure someone would love to have it.

I agree, a very tidy install.  I do not think I will try a 9" either.  The 7" looks great!  Thanks for the picture.

If you have a coach with the electroluminescent dash, that is a wise decision!

Damage to the circuitry will cause the dash to cease illuminating.

Great advice from Michelle!

 Our 1995 U320 has the simple dash and so I wasn't concerned about modifications. If we would have had the electroluminescent dash I would not have enlarged the original monitor opening, and instead used something like VHB tape to mount the monitor to the dash face.

Just to double check......

 After removing the old CRT box, this flat monitor will directly accept the inputs from the stock system?
 Hook up one RCA cable, provide 12 VDC, mount it up and it shows all the levels that I had before?
 Switch functions remain the same?

I believe that will be the case, except that you may need to purchase an adapter to go from one type of video connector to another type.

Mine has the BNC connector on the audit box. I ordered an adapter to adapt the audit box from bnc to rca then I will just use a rca video cable to connect it to the monitor.

How do you tell if the dash is electro-luminescent?  When I turn on the lights, nothing on the side panels appears to light up and it just looks like sheet of steel to me.

Right there in the photo that shows the label, the part number has E.L. (Electro Luminescent) in it. There should be an inverter power supply zip tied behind the panel below the dash. It is a black box about the size of couple of decks of cards stacked.

Thank you.  I will look for the power supply.  I sort of wished it was not so I could enlarge the opening for a new monitor.

You must rotate the dash brightness knob to see the glow.

To add to Bob's comment, keeping the brightness all the way off or way down can stress the variable resistor (control knob) and or the inverter power supply causing an early failure.
