Can I use just the amp from a home receiver??

[Vigilante]

Hey guys and gals, question:

I have a 600W 5disk DVD changer, a Panasonic SA-HT670. The unit "would" work, except for the drive trays screwed up, and the dude who had it, was just forcing the trays in and out until it just busted completely and none of the 5 trays work anymore. Let me put it this way, the WHOLE of the disc changing/playing assembly no longer works.

However, the unit itself still works fine, I can output the FM signal to my speaker and all seems normal. The problem is that the unit thinks there is something going on with tray 1. The Tray1 light is on, and the disc1 graphic in the display is blinking. And so the unit will only switch to FM/AM and back to CD. It will NOT change to any other inputs, which it has 3 inputs. It just won't do it.

So we took the whole drive assembly out and took the control boards off. We were messing around with pressing the various switches on these boards, but any of the switches pressed, or ALL pressed, doesn't change what the system thinks is going on.

Thus brings me to my question. I can't get the unit to switch to aux input because of what it thinks is going on with the DVD. Is there a way to FORCE it to use aux input? Or in other ways just "pull" the amp out of it and use it standalone? Is there a way to trick the unit?
Nothing we try makes it stop blinking the DVD and lighting the Disc1 light. Even disconnecting the two ribbons from the drive tray and pulling the whole thing physically out of the unit and disconnected, it STILL blinks the disk1 as though nothing even happened! The entire 5 disc changer/player unit is gone out and I still can't switch to aux input or any other input but FM.

This is bugging me, I'd like to use the 600w amp in this thing. ANY and all help and suggestions please don't hesitate to say your peace! Thanks.

find a local authorized dealer. tell him what you want.
he'll probbaly be able to snip a couple wires make two of your RCA INputs and tap the wires into the PA section input (usually two wires..L & R).

then you have a Power Amp....no volume control, just a pure amp like those without volume knobs. straight thru.

your pre-amp/volume knob will be your recorder/faders or what ever your using.

Like the previous post says...basically, you need to be able to bypass the preamp section of the receiver so that you can send the outputs from your mixing board directly into the amp. Either it has a preamp in (which I doubt) or you can possibly build around it. If you use the preamp inputs (like the RCA's) your sound will be linited by the capabilities of the receiver preamp...

Hmm, Panasonic listed each of the wires from the ribbon cables. Each of the controller boards don't "talk" via "wires" like I could easily bypass or jack in to. It uses a thin ribbon cable that I doubt I could rewire.

The other twist is that it has a decoder in it for 6.1 channel sound. So this ribbon cable handles not only L/R but subwoofer and center, surrounds, etc... Which means what? That I would have to take each audio signal, put them all together? I was thinking I could maybe hook just the center channel and sub together?

Similarly I want to ask, how sepparate can the pieces of this unit work? I mean, if I disconnect all the front panel stuff, can I still make the amp power up without the "button" on the front display? I'm just wonder so that I can strip this down to only the pieces I need, and then see what my options are.

If you like, I can get the unit and print what the pins are on the ribbon cable.

Oh and one more thing, since it CAN switch to AM/FM, can I pull the tuner out and hook my input to those connections somehow?

Thanks, I'll look around for a dealer, but people around here are not that technical, nor would they do something like this for me. There's only a few audio shops around here but they are mostly retail.

thanks, I WILL get some sound out of this thing if it's the last thing I do!
