View Full Version : DCB152 "Motorboating" on start up

I bought my DCB152 earlier this year but cannot locate proof of purchase to use guarantee. On switch on with the remote, the unit SOMETIMES immediately goes in to "motorboating" ie gives out a series of noises (like small burps) at about half second intervals. No radio reception occurs and the only way to stop the noise is to disconnect at the mains and leave for several minutes. We switch the unit on once or twice a day, and this problem occurs about once every week or two.

Can anyone help me sort this please?

can it be some sort of interference?
how long does that last?

Not aware of any source of interference, but could be. Effect lasts until I switch off at mains socket, leave for several minutes, and switch back again. Someimes it restarts OK, others it motorboats again.

Local repairer suggests it is probably faulty audioi chip, which would cost about 40 to 50 plus VAT.

Fortunately I found (on-line) receipt for item and although just 2 months out of warranty, Phillips are willing to exchange. Good for them; that's what I call customer service.

I've just bought one of these second hand, with a declared CD problem - "sluggish opening". I often get the motorboating sound when switching on, but it comes from the hardware, not via the speakers and I think it's the CD mechanism struggling: the tray never opens :-(
I find it also fails completely on the USB input. It will make my Rhino mp3 player switch on, and occasionally make my Sandisknmemory stick flash, but shows no other sign of seeing either device.
As the CD and USB are lumped together in the manual, could it be that there is enough shared circuitry for them both to be suffering due the same fault? Alternatively, one of the FAQs says to connect an "unsupported" USB player via the mp3 link (which certainly works) - but I can't find a list of supported devices anywhere.
Can anyone offer any suggestions at all please, for this out-of-warranty unit? Alternatively, any advice on getting the case open would be appreciated!!!
TIA

I think you could be right about it being the CD player going nuts. Beware that what starts out as an occasional problem may become permanent, as it did for me. I can't comment on how to get your stuck one open, as it is not something I used much. Have you tried talking to Phillips customer support (phone no from their web site)? As I said before, they were very helpful. They may put you in touch with their technical specialists.

Cheers

It will make my Rhino mp3 player switch on, and occasionally make my Sandisknmemory stick flash, but shows no other sign of seeing either device.I've got lucky! I tried it with an ancient 128M USB1 stick and it worked. Then I progressed up through 1G, 4G to my 8G USB Sandisk and it's still playing. Oh frabjous day!
No more motorboating at the moment, either. I still need to know how to get into the case to have a look at the CD though - it appears to be held in place by special screws(?) with just a tiny hole in the flat top. Anyone recognise them please? (The Safety Elves may stop Philips from telling me how to get it open :-))
Thanks.
