My problem is very similar. I have the main unit plugged in along with the subwoofer. The power light remains on. When I hit the power button to turn it off, go to the main unit to press open/close on the DVD player, or hit input selections on the main unit, the light on the subwoofer and main unit goes off for about 2 seconds then turns back on. I have to unplug the unit in order to turn off both the subwoofer and the main unit.
Everything is plugged up properly but I'm not gettin anywhere with setting up the home theatre system. Not sure if it's a fuse or not but certainly a power issue. Any help and/or suggestions anyone can give would be greatly appreciated.
Unplug all of the speakers and power on.Its possible that one of the speakers is causing the protection circuit to activate.If powered on and subwoofer works start reconnecting one speaker at a time( after powered off) and retest each time.One Speaker may be bad.Its also possible the output ic is failing under a speaker load.There are no fuses related to this issue.If its not a speaker problem then the subwoofer will need to be serviced.

Need a bit more info. Have you checked the power at the power point? plug a lamp or similar into the power point to check. Are there any indicator lights showing on the front of the machine? could be a main board, have come across a whirlpool wfs1273bd with a similar problem yeasterday with a similar issue, pwer to the main board but nothing out.
If the system is connected properly and the main tuner power is on you will see the orange standby light on in the front of the main diamond shaped control unit. If that light is not on, you have not connected the system and power cables properly.
If the standby light is not lit, press the power on/off button in the middle of the rectangular processor/tuner to turn it off and unplug the main power cord from the main tuner/processor from the wall. Next, ensure that all of the power, video and audio cables from the diamond shaped control unit are properly connected to the large tuner/processor. Since you are there, check any other av in/out connections.
Now that you have checked and adjusted the cables between the controller and the tuner, plug the tuner back into the wall and push the power on button. Now check the standby light again on the diamond shaped controller unit.
Once that light is lit, press the silver, horizontal on button in the middle of the diamond shaped display unit, or the Power Standby/On button on your main remote control and you are operational.
One thing is to make sure the inverter board is unplugged when testing the voltages. A shorted inverter will shut down the power supply if the fuse dosen't blow first. There are fuses that don't look like fuses so they can be missed. The next thing would be to look for a connector from the main to power supply and see if there is a pin labeled power on or p.on or similar. The main board should turn this line high(5V) when you push the power button. If not you probably have a bad main board. Unless you can find good used boards they are both expensive. Around $200 for PS and $300 for main.
I have several of these units due to being a liquidation seller, and the MOST common problem is the subs not getting any power. Next is CD Player Dying, and 3rd, unit powering, but not sending info BACK to the sub.
In any case the issue with the subwoofer is rarely the fuses. It's further up the line. So far every unit we have checked the transformer was the culprit. If you are handy, by all means replace the transformer and you're better to go.
okay, this seems like either the fuse hase blown in the actual mains plug, or the mass fuse inside the device, it looks like this very small glass fuse, same size as an ordinary fuse, its just seethrough. see if you can get a replacement for it, you may need 2 open the unit to check if it has blown, it will be black or a "burnt" colour from inside! if you dont want to open it, take it to any electronics store, they are bound to check for you, but these fuses don't cost more that $1 or 50pence!
There are 2 things you can try, first ensure that the digital transmitter is fully inserted into the slot of the main unit. Secondly do you have any other wireless devices near such as cordless phone or wireless network equipment? See page 5 of the installation manual as per this picture.......
