Repair Casio CZ-1000 Phase Distortion Synthesizer Reparatur Service30. August 2020
A customer brought in a synthesizer puzzle. He tried to repair the display but desoldering the backlight may not an easy task. I suggested, to switch over to a new display. These are cheap and their different colours look beautiful..
See the agressive electrolyte coing out of the old capacitors. If you plan to replace such display, you have to modify the power supply to the display. By doing that you will also eliminate the annoying whining noise from such synthesizers.
While I was in here I saw a lot of rust and corrosion. So I suggested to get rid of it. All these tactile switches had to be replaced.
But there was rust everywhere.
I cleaned all the (surface) rust, applied some rust converter and protected the surface against new rust.
There are lethal voltage exposed in electronic devices. Unless you know what you are doing, don’t try this. If you following along, you doing so at your own risk.
I’m documenting repairs for my reference and yours.
