Question about Philips FWC550 Shelf System

1 Answer

Power shuts off

I have a Phillips FWC550 Shelf Unit that will immediately go to EcoPower mode after I turn it on. This happened after I plugged about 6 speakers and a sub-woofer into it. It all worked until I turned the volume way up and it just shut off. Any help would be appreciated.

The unit is in "protect" mode. Basically a problem is detected in the last output stage of the amplifier section and the unit shuts down to prevent further damage. I suspect that you connected too many speakers to the system. The impedence load was too low for the amp section to handle and one or more output transistors have failed. This should be a straightforward repair for any local repair shop. Figure on $20-$40 for parts plus the local labor rate for the repair. I am not familiar with your specific model, but these shelf units are all similar in design. I will try to locate the service manual for this one to get you more details.

Need user manual to operate fwC550 system


What country are you in? You may be getting the local Philips support page. I found a tri-lingual (English, French and Spanish) manual for the FWC550 here: http://www.p4c.philips.com/cgi-bin/cpindex.pl?ctn=FWC550&hlt=Link_UserManuals&mid=Link_UserManuals&scy=US&slg=AEN . The direct link to that manual is http://download.p4c.philips.com/files/f/fwc550/fwc550_dfu_aen.pdf . This copy has some pages duplicated with unreadable pages followed by better scans of the same page. Thus the English section is from page 1 - 58.

I hope this helps.

How do i turn off the demo mode?


The "DEMO" mode initializes when power is initiated in the unit for the first time.You cancel it by turning turning the power on by using the button the unit or the remote.If you unplug the unit from the power outlet between uses, and plug it in again...it will go back to the demo mode.this can be avoided by leaving the unit plugged in between uses and/or install 3 AA batteries in the battery compartment in the lower rear behind the main battery compartment .these batteries are memory storage.it is not necessary to instal the 9 size D batteries for portable use unless you use it as a portable...I hope this was helpful...

Power problems


The set is detecting a problem internally and shutting down to prevent further damage. This is often call protection mode. I would guess that there is either a bad connection somewhere or a part starting to fail. If there is a pattern to the failures, a quick trip to the repair shop is in order armed with that info. Rough guess would be abaout $30 in parts plus the local labor rate. This is based upon my own repair experience with these systems.
