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!

Re: Auto-stop malfunction and stuck cassette door

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!

The diplay will not work. Any suggestions?

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.

Cassette players jammed

actually you can not lubicate the cassette players. it has to do with a belt inside. your players may need to be demagnitized. i would go to radio shack or electronic store and try a cassette cleaner/demagnitizer and see if that solves the problem. i would even try different batteries or a ac power adapter if you have the plug. some batteries make units run slow. i would even get a can of dust cleaner that you find in the electronics section. you spray it in and it cleans the inside of the dust that may be inside.
