Re: RCA Wireless Speaker System WSP255RS

This ia a new item for me. I bought it on EBay a few months ago as a refurb. The first one I got would crash after a few seconds. I sent that one back and got this one. I tested it for about 15 minutes and it ran well. So, I boxed it up and figured I was set for the summer entertaining on the deck. ...

Hey Sambuchi,

I am impressed. Who did all your PCB work?

Re: RCA Wireless Speaker System WSP255RS

I want to thank all of you for your quick response and your help. It appears the problem was indeed caused by overheating which caused the circuit to shut down. The transmitting section is sealed in a metal box, which probably is also supposed to function as a heat sink. I pulled the entire circuit ...

Re: RCA Wireless Speaker System WSP255RS

jwax - Thanks for the info, it will help a lot. Now I can dig into the thing and at least know what I am looking at.

I am aware of the "no audio" feature of the xmtr. That is not the problem here.

I wonder if anyone else has had a similar problem with this system?

Re: RCA Wireless Speaker System WSP255RS

The wall wart does not show any signs of heat. But, I have not monitored the output voltage to see if it does drop off after a while. I will try another supply to see if it makes any difference.

The FCC ID is N0YRF93.

Re: RCA Wireless Speaker System WSP255RS

It can't be dusty because it is a sealed saucer shaped unit. Thermal overheating probably is the problem. But, without any tech specs, I don't know if the transistor is bad or just can't handle the power requirements. The whole unit is only 4" in diameter.

RCA Wireless Speaker System WSP255RS

The system works fine for about 10 minutes. Then the transmitter shuts down. This seems like an overheating problem, or maybe a weak transistor final. I have not been able to find a schematic or any kind of technical info on this system. Any help would be much appreciated.
