I recently received this accurian wireless sender (15-1938) and accurian wireless speakers. The sender does not power on and I believe (hope) this should be a relatively simple fix. I traced the circuit board via the images with my volt meter and lose power on the output side, of what I am calling, the power transformer. I was hoping someone here could look at the high-res images I have linked below and give me some suggestions on repair. I am a laymen and that might be pushing it a little...
I look forward to some suggestions
Here are the images:

A wireless sender that uses a Realtek 8019 LAN chip - interesting :)
By the look of it, the power transformer is toast if you cant read any voltage at all (it will be AC) on the secondary side. It's not likely that you'll be able to get a replacement unfortunately. |

I happen to have a spare board if you would rather replace the whole thing. PM me if interested.

The board does not allow me to PM users yet, I am too new. Email or PM me an image(s) and to let me know the price and I will certainly consider it.
Thanks |

Hi,
IIRC I have 5 of the receiver boards that I have no use for. As far as I can see they use an identical transformer. If you are willing to pay shipping you can probably remove the part and re-solder it to get what you need.
If you search for "accurian" you should be able to find the thread I started in the trading post trying to give the things away, if nothing else you can see a picture.
Let me know what you think

Email sent. I was unable to attach pictures through the forum mail function, but if you reply to my mail I will send them shortly.

Paul, take a look at my board in the images and if the transformers look the same let me know how much shipping will be 37064.
Thanks,

But they look pretty darn similar to me...
In fact comparing the pictures we have each posted the 'sender' and 'receiver' boards look very similar too...
Perhaps they are really the same and I just need to figure out the right jumper settings to make my 'receiver's into matched pairs.

Hi Stuart,
Wondering if you figured out how to use an RX unit as a TX unit?
I see that the output connector says A-OUT, the one next to it A-IN, hmm, that should be a hint. There is a single jumper (CON4) on the board but not sure what it does.
If anyone has a transmitter, is the jumper on CON4 in place or removed?

Yeah, through correspondence with Michael (wirelessrat) we (he) changed a receiver into a sender by exchanging the small socketed rom. The boards are identical, it is just the firmware that changes...
If someone out there can burn these parts to make a couple of my surfeit of receivers into senders it would make what is currently a lot of junk useful...
Hopefully Michael can address your other questions, I'm still transmitterless, so not sure of jumper settings etc...

| Thanks - now where to get the ROM? |

...Michael
though he might not want to be without his toy for the week or so it would take to send it to someone etc.
Do you have the means to burn the proms?
Stuart
Oh wait, there's a certain ambiguity here, did you mean the original e-prom image for a transmitter? I haven't checked part numbers but there is a good chance we can simply reprogram the parts we already have.

OK, I've worked in digital electronics for many years so sure I know how to program a PROM, EEPROM etc. But, I don't have access to a programmer at the moment, or an original to copy, so that's why I asked. I just need one transmitter, two would be nice, I'll probably look on ebay.
Yes, if the original is a reprogrammable type such as EEPROM or FLASH, we can reuse it.
The RX prom is labeled: RS, 0624, R
I'd guess that RS is Radio Shack, R at the end for RX version?
PROM is cheap these days, I'm surprised that they didn't put both in one PROM with a page select to choose the mode.
I'll keep an eye out for a transmitter.
Thanks again,
Pete B. |

| Guys sorry I can not help. I got rid of that thing shortly after the donor was so kind to send me that receiver board. Now I am wishing I had the thing back to use with the nice speakers that go with the sender. |
