Chosen Solution
I have this “goodwill special” system that looks to be in good shape with the dvd player missing. This system consists of a DVD player (missing along with system cable), a powered subwoofer, rear wireless speaker (powered) , FL , FR, Center speakers. I imagine the dvd player failed and some tossed it a long time ago. My hope (with some assistance) is to use the speaker components to plug into a receiver normally. I’ll included pics to help this along. Apparently this piece of the component system controls the on/off signal to the main amplifier built into the main sub. Of course it has a proprietary “system cable” that alot of manuf incorporate into their systems now. This plugs into the dvd player into the sub. I need to know if I can bypass the need for having the dvd player and remote allowing use of this sub and speakers as a standalone system connected to a receiver. The sub does have an auxilary input L and R rca but this does not activate / turn on the sub when a device is plugged into it. The sub is an active sub. I’ve taken it apart thinking I could get the datasheet on the IC amp chip but do not know how to read / understand the pinout. I’m good with solder and know basics for a mulimeter. I just need someone to locate the circuits / pins to bypass if any “standby” mode exists (see pics). I’ve performed a similiar fix on a sub for a bose 3-2-1 system (big dissapointment there ). It’s rediculous what bose charges for their sub-par systems but thats just my opinion. That’s another topic. I appreciate anyone giving me any advice on this. It has some pretty large drivers and the system has good reviews. Could this be as simple as a jumper at the system cable connector??
Edward Anderson there is a lot of stuff in your Question. I am old so I easily confuse. You want to plug a receiver into this so you can use it as regular multimedia system, without the DVD player is what I read. I don’t think the DVD player is really necessary for that. Anyhow here is what I got. The “proprietary connector” is CN400 so take a look at it and it is quite complex.
These images are large so you want to open them with a graphics viewer and not just on iFixit. Not sure what you want to connect to the “IC amp Chip” (which one were you looking at?) Update (10/05/2020) Edward Anderson of course we are still looking at this and trying to follow you along as well as finding a solution. Anyhow, here is the schematic for the CD/DVD player
