Display seems frozen

The power went out for the night, then went back on. First the time was frozen on the display but nothing was working with or without the remote. I put a fresh battery in, unpluged the radio for 1 hour, now I have "Soundworks radio showing on the display and again nothing will work not even the power on and off. Help please.

How do I get the battery to operate the clock when the power is off. I have the battery in correctly, but when the power is off the clock goes off?

I just read the manual an I am not sure it does. The manual says nothing about that. My clock does the same when power fails. Comes back to correct time when power returns. I miss that on my older clock. Display never went out even during power outage. You can call Phillips an ask or email. It is on there site.

They're just used to retain memory. That's all. Once power comes on, the time should be correct. Now if the power went out and there was no battery on the clock, when the power comes back on it goes straight to flashing 1200.

My Coby CRA108 starting doing this after 6 months of use. Although I described the display as 1P:C8 since there is no key to properly display the character (hybrid of a G & C). I've left it unplugged and changed the backup battery with hopes it would reset. No luck so far. Anyone have success???

There's a line fuse for these sets inside the radio on a printed circuit board. NOTE: for your safety, disconnect the radio from its power source before you open the case and poke around inside. The best way to check the fuse is with an ohm meter, but you can probably check it visually using a strong flashlight. There should be a wire filament running the length of the fuse. If it's intact, so is the fuse. If it's broken or not visible at all, the fuse is "blown" and needs to be replaced. If the fuse checks out ok, the power transformer is likely bad -- a problem that these sets are notorious for. Bose will charge you $100 for the transformer repair (unless the set is still under warranty), and having it done is strictly a matter of personal choice. My choice would be to sell the Bose on eBay as a "tech special" and pick up one of the newer HD radios. They offer much better sound at a much lower price.

Bose not working at all

Unfortunately, Bose will not release their schematics of parts lists, effectively giving them a monopoly on repair of these sets. On their web site,, they offer to repair most Wave sets for $100 or give $200 credit towards the purchase of a new Wave. Before you spend the big bucks though, you might want to check out the new HD radios. Better sound and MUCH lower prices than the Bose.

check the rectifier next to the transformer, the dc out should be around 15 volts and the big main cap as well.

Drop the superstitious ****. The iWake clock radio has two components in it that, when brushed together, turn it on. This is an unusual occurance, but it does happen. Here's how to fix it. You must purchase a 352 page book and prop the iWake on a 23.14 degree angle. This will cause one component slightly lean backwards, causing the components to never brush up again. Or, you could take up exorsism and cast spells on it to try and shoo the evil iSpirits away.

Clock radio frozen in time

I have it too, and I think it has something to do with the timezone, so try resetting your timezone, and then the clock. it was happening to me, and I fixed it somehow. hope that helps.

Projection display

I had the some problem a few days ago when we had a power outage during the night. Try unplugging it, leave it unplugged for about 10-20 seconds, and replug it back in. Reset your time on the clock and it should work then.
