Tip & How-To about Cambridge Soundworks Audio Players & Recorders

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
