Question about Sony PSYC ZS-D55 Cassette/CD Boombox

1 Answer

Auto-stop malfunction and stuck cassette door

My Sony ZS-D55 is two years old and has been used in a clean environment with batteries only. It has recently begun clicking at the end of a fast-forward or rewind action, and sometimes shuts off, sometimes not (as if auto-stop is trying, but failing). Yesterday, it decided not to release the tape-drive path machinery and will not do anything but click three times, and, accordingly, the cassette door will not open. Meanwhile, a rented audio-book cassette seems to have found a comfortable new home with a lock on the door!

    Thank you, Fairlane, for your help. I tried removing all power (batts and ac) for a couple of days, and when I reinserted the batteries and pressed "power," the cassette door opened and released the trapped tape. I think you are right on the slipping drive belt: it occurs only during FF and RW, not during play, and I have ordered a factory manual to assist in checking/swapping the appropriate belt.

    I appreciate your time and expertise!

    My Sony zs-d55,s CD player stopped functioning first. It would start spinning and THEN STOP. NOW THERE IS A CLICKING SOUND if i try to play a tape. The radio alone works now. Its so upsetting as i bought it on a trip to America and i cant find anybody to repair it for me here. They say the lens is the problem and charge me for a new lens, but i still seem to have the same problem.

Hi I'm not familiar with your particular model, but the auto stop problem is common and is usually the result of a slipping drive belt, or bad idler/reel drive. The auto-stop works by popping a small tooth like plastic or nylon piece attached to an arm, when you runout of tape and takeup reel pulls the tape tight. The auto-stop mech can get contaminated with dust, and not work, or the reel for some reason does not pull the tape tight enough to fully engage that piece and the result is a ticking sound. As the deck now has your tape, I suspect the main drive belt is broken or probably slipping, and all will work fine if it is replaced. Although changing the belt is not difficult, you should probably take it to a repair shop, as getting the right size is important, and the deck may have to be dismantled to change it. Hope this helps, good luck!

Some displays have one or too bulbs that are solded to the board to highlight the digital display usually hidden behind the screen, this is a very difficult repair because it requires a complete dis-assembly to get at the parts, but if the display is completely dead there is no voltage reaching the display ic.

Sony ZS-DS drops all stored data i.e. Radio Stations, Clock time etc even with a new set of data backup, AA batteries. Any ideas on this problem or is it time to replace it?

Check the metal battery contacts at the set for any rust or dirt accumulated on springs of pads, restricting the flow of current from backup batteries to the inside circuit of the set. Backup batteries should be replaced after 12 months periodically to retain data. When you replace the battery, the data stored will be lost, and you have to re-enter all the data once again. OK.

Sorry I can't directly help with your problem but I advise you the repair cost at a repair shop would probably cost nearly as much as a replacement...

Unless you have a handy friend who works cheaply you won't lose anything by repairing it yourself. You will probably find some useful how-to videos to help you on Youtube.
