Casio CZ/ VZ/ FZ - Pro Series

Sounds indeed like the transformer died,you can indeed check the output with no board attached or test the output coils (whilst not plugged in) with a resistance meter - which should show low resisitance - infinity means it is busted.

You do not need a casio replacement,but you do need to know the current rating and the value of the output coil(s) voltage(s).

      Hello

I tried to clean my good old CZ-1 yesterday and suddenly, after putting it all together again - it died completely. No LED, no lights on anymore, just nothing. I checked the input voltage at the transformer, it is as expected 230V. There is no voltage level on the secondary part of the transformer (while the board is still attached - ie. I did not yet try the transformer without the attached board). So all the 15V and 5V supply for analog and digital circuits are now unavailable (almost 0 V). The fuses are all OK, so I suppose it is in fact the transformer that died... or does the transformer switch off automatically in case of a short circuit or high temperature? :-(

Did anyone of you guys have similar experience? Do you know if I can replace the transformer easily, will a universal transformer be OK for the CZ-1? Or do I have to buy a special one from CASIO? Probably it is not available anymore anyway....



Thanks for helping out a little.

Cheers

Terry
