Concertone not working

I have a Concertone dvd player in my 2009 Rockwood ultra lite 8306SS. On my way down to Myrtle Beach it quick working. No power to it, checked fuses at fuse panel. Pounded on it and still not working . Any ideas??? Everything else in camper works including TV. It is not the GFI either, checked it.

There is an inline fuse behind the unit.

Color me curious, why did you think that pounding on it would fix it?

Just checking if it was something loose. It was more of a tap, pounding was what I wanted to do.

How can i remove to check fuse? I didn't see any opening like a slot to stick a screwdriver in.

No bad manners at all!

That was me just trying to be funny (and failing miserably).

Look at the bottom of the unit, there are 2 slots for a flat bladed screw driver.
CAREFULLY insert the screw driver and twist; the cover at that corner should pop. Continue carefully lifting around the 4 corners until the faceplate pops off and you will see the 4 mounting screws.

My 2009 Wolf Pac 16 DFWP has the same Concertone unit. The alarm clock kept going off at 2 am. I went on the web and found an owners manual (PDF). I also found several post regarding multiple problems with these units. Mine was junk-could not shut off the alarm and it could not be repaired. I was fortunate and found one (new)on Forest River Forums. Best of luck. Googmiester

Mine quit this spring and after researching a little I pulled the fuse out for a minute or two then put it back in. Started right up basically resetting it.

If your talking about the fuse for the radio at the breaker panel, I tried that also but no luck. Thank you.

There is a blade fuse in the back of the radio.

Hey Herk, here is an update on my radio issue. Panel came off like you said and when I pulled the radio and all the wires (which is in abundance) I found a large mouse nest made of paper towels and facial tissues. The only wire I found chewed was the FM radio antenna cable which I repaired. Checked both blade fuses and they were both good. Checked for power with a 12V test light and had power everywhere it should be. Scratching my head I checked the wire harness's that go into back of radio and what do you know, radio came on. Made sure all was secure and mounted radio back. Thanks again for you advice. We are heading for Hueston Woods State park in Ohio soon and was hoping to have system up and running. Thanks again!!!

Used to work to shake tubes back in the socket, really!

Too true. I remember the TV technician making house calls when I was a kid (hold cow talk about old) and saying that hitting the cabinet to "knock parasites off the cathode ray tube" was an acceptable practice and that will still be 20 bucks...

I really do like learning about this machine we call an RV. Whenever someone finds I fix I file it in some of those vacant (aircraft only) brain storage cells.

Only fair to share...

I had mine out to try to find a 12V source for something else, and man, what a bunch of wiring to that thing!

It had been "permanently" connected to the trailer wiring by those clamshell splice things that bite through the insulation and you squeeze with a pair of pliers. As an aviation electronics guy for nearly 40 years, those things give me the creeps. Plus, as I was digging around for my power source, some of those wires started coming loose.

So last weekend I spent a couple hours removing each and every one of those silly things and doing the splice properly, with solder and heat-shrink tubing. I also labeled both sides of every connector so that now I not only won't have those nasty little things causing trouble, I can remove the whole unit if I need to work back there.

Some people swear by those splices. I swear AT them. They're great, IMO, for a temporary repair to get you home; I don't believe in them for a permanent installation, though.

YMMV

True statement.

Years ago, I had to maintain a half-dozen aviation radio beacons (non-directional beacons, to you pilot types) in the Colorado mountains. They were old enough that I think Orville and Wilbur found their way to Kitty Hawk with them. Anyway, a "percussion adjustment" was exactly what it took sometimes to get those tubes glowing and working again.

I was valedictorian at my school, the "Bigger Hammer School of Airplane Maintenance". Our motto was, "IF IT AIN'T BROKE, YOU DIDN'T HIT IT HARD ENOUGH".

Does anyone have a picture of a blade fuse for those of us who are not electronically inclined?
