Recoton/Optimus 900MHz loudspeaker transmitter repair?

"The CHARGER jack on the transmitter is for charging the RadioShack PRO-100 Wireless Headphones (Cat. No. 33-1145). Do not plug any other device into this jack"

No worries on that as the plugs are clearly different but is there anything which can be cone to resuscitate this unit or obtain one elsewhere?

If the unit is completely dead, then I would expect to be able to pin down the cause of that with reasonable certainty, with just two or three measurements. If you don't have a suitable meter, or are unable to determine what those measurements should be, then no disrespect intended, but reviving this item without at least schematics, is likely to be beyond your skill level. Sorry.

I scoured the web for a schematic for the speaker side of the system several months ago. No cigar. I can probably trace out what I need when I get around to it. I basically want to tap in an audio signal to use them as standalone amplified speakers, which shouldn't be too tricky.

If the transmitter is totally dead, it's probably a power supply issue. Step 1: check the wall-wart supply & make sure it's putting out the right voltage. If so, there's probably something simple that died internally. If the wall-wart is toast, it could have been killed by a shorted capacitor inside the transmitter. That level of troubleshooting shouldn't be too tricky without a schematic. Beyond that, it's a lot of work to repair something without more documentation.

If the OP gives up on fixing the transmitter, I might be interested in picking up a pair of extra speakers.

Are these speaker of adequately high quality to justify the level of bothering you are employing? Or doesn't it matter all that much once you have gone over a certain threshold with rear speakers in a home theatre setup?

First thing I did was to switch AC adapters with those of the speakers (same voltage) to isolate the problem to the transmitter itself.

Thanks for your message, t I sorta figured that if nothing happens when you plug it in, it is probably a power supply issue 'cos before you even start to get into circuits, that is PROBABLY what sends juice to the LED:: This is a Radio Shack unit, one would have thought that it was possible to buy a power supply somewhere? Surely easier than trying to find a transmitted for a unit which burned out its transmitter so often?

I need battery powered speakers for a small PA application, and they are higher quality per $$ than anything else I've found.
