Polyspan soundstation power supply schematic diagram

I'm sorry, but I am not able to provide specific service manuals or schematic diagrams for specific products. I would recommend contacting the manufacturer or a authorized service center for assistance with obtaining a service manual or schematic diagram for your specific device. They may be able to provide you with the information you need or point you in the direction of a resource where you can find it.
In general, when troubleshooting issues with a power supply, it can be helpful to check the voltages at various points in the circuit to determine where the problem is occurring. If you are not getting the expected voltages at certain points in the circuit, it may indicate a problem with the power supply or with components downstream of the power supply. You can use a multimeter to measure the voltages and compare them to the values specified in the service manual or schematic diagram to help diagnose the issue.

if you think that you are able to do that

Very simple one

If you have a schematic diagram of the power supply you would have to check for the feed back circuit which comprises of an error amp and an optoisolator check around that circuit and change any faulty component that should solve the blinking condution and thus will bring on the power supply

You need a meter to test the voltage else check the manual or normally it is written on the transformer about power,voltage and current.Hope this helps.

Polaroid will not release component schematics not even to service centers as they are designed to replace the entire modules while under warranty out of warranty there is very little Chance of obtaining new replacement parts. As i have a 2006 LCD and a 2007 Plasma Polaroids and polaroid told me they are considered a disposable TV replacement parts are not available and suggested that I try ebay

You have something in short circuit in power supply pattern, so filter coils are burnt. It may be voltage regulator, or regulating transistor, electrolytic capacitor or even shorted diode at pwr. input serving to protect in case of inverse polarity applied. Check all for short. Was it reverse polarity or overvoltage occured?

1-change telephone cable from your machine to wall outlet if the problem fixed it is ok,if not you must contact your phone company because noise may be in telephone line itself.

Someone in our office recently damaged the RJ-45 cable for our Polycom Soundstation. Because the jack was damaged I could not determine the order of the cables. After a call to polycom, we found the pinout information we needed - so I thought I would share, in case anyone else finds themselves in a similar situation:
With the RJ-45 prong pointing down the wires, from left to right are:

• Black
• Brown
• Red
• Orange
• Yellow
• Green
• Blue
• White

Then Crimp and test. I got this information directly from Polycom for use with the Polycom Soundstation. This information was not easy to get. They originally told me they could not provide the information and I would have to buy a power adapter. This is not true, just trim the cable and follow the above instructions.
