Flickering and faded display

The display on my Cambridge Soundworks Radio CD-740 has recently started flickering and faded to an almost unreadable state

Are the component replaced?

The instrument has performed excellently and would prefer to repair than replace

    I haven't really done anything. I made sure no items were blocking the display. It seems to work better after I shine a light at the front of the unit, but it only works for a day then goes dark again.

    Hello - we have the same product and the same problem. Purchased in October 2004, it has worked flawlessly until this past summer when the LED display started to fade, then came back for a few weeks, and now it totally "unseen."

    I just contacted Cambridge Soundworks today to see if they can help with regard to a repair for the display.

Dead Cambridge Soundworks 740 radio

I spent $300 for the thing 10 yrs ago, then paid$125 for a display repair, now its crapping out repetitively and I refuse to pay ungodly sums to repair it again only to have the next thing fail in a few yrs. So, I plan to gut mine and convert to a speaker dock for my iPhone - small mini-amps are under $50 now. I plan to leave the speakers in the case since they are properly ported and sound great as is. I'll pull the speaker wires out the back and mount the amp on top - might not look pretty but it'll work just fine and some of these little amps have FM tuners, SD card readers and remotes. won't be as elegant but it'll sound good.

Cambridge soundworks radio 730 display and or controls lock up

I recently posted a problem with a cambridge soundworks 730 which had a display problem with unreadable characters and/ or ALL of the controls would lock up after being on for 1-2 hours and could be fixed temporarily by unpluging and then pluging back in Luckily I was able to find another display board and that took care of the problem and eliminated the tuner board and the power supply board in the back as possibilities. there are several chips on this board so a service manual would be necessary to pinpoint this particular problem or a replacement board from the manufacturer OR buy a broken one on ebay that does not have the same symptoms and make one good one out of two and you will also have extra parts.BE CAREFUL WITH THE RIBBON CABLE WHEN YOU REATTACH IT TO THE DISPLAY BOARD its a little tight and must be pushed back in evenly.It might be easier to take the whole radio apart and disconnect it from the tuner board which is a straight run whereas on the display board end its at an awkward angle

How do I set alarm? Instructions long gone

To the left of the display are two buttons, engraved "1" and "2". (Note, I'm NOT referring to the buttons for radio presets, which are below.)

Hold either of these buttons for a second or two to enter alarm set mode. The screen prompts will prompt you to set the time for the alarm to go off using the time set buttons to the right of the display. You can also press one of the radio preset buttons or the AUX or CD buttons to wake to one of those. Once you're done setting the alarm, quick presses of these alarm buttons turn the alarm on and off and choose between music and beeper.

As a side note, if you've installed the backup battery and the power fails during the night, the alarm will still go off with the beeper so you're not late for work -- a thoughtful touch from Cambridge Soundworks.

Soundworks 740 fuse

See my answer to cd740 sound cutting out. Fuse is inside near the transformer. You'll need to disassemble. There is a good write up for a question about getting to the faceplate. Briefly, there is a sub base that has screws hidden behind the rubber feet pads which peel off easily. The front speaker grills PPP off easily and it hides some screws. The rear plate also has to come off. Check those other questions, the answers will help.

How do i replace burned out lightbulb in my in my cambridge soundworks cd - 740 clock radio ?

I believe the problem is either a faulty light sensor the unit has to dim the display when the lights dim since it was designed for bedroom use with alrms and snooze button. or it is simply a failure in the circuit that drives the LCDs. Mine has been dim for a long time but I can still see just enough to adjust the sound settings. I tune and set stations by sound. so the display has not been an issue since we do not use it for a clock or alarm. I doubt there is a fix for the dim display.

I just had the same problem and called tech support (800) FOR HIFI at Cambridge Soundworks for help. All you have to do is unplug the radio for 30 minutes and then reconnect - kind of like rebooting a computer.
