Hi everyone,
I recovered an ESQ1 which has been stored in an unheated shed for about 20 years.
Although it looked in great shape, when I tested it, it started up but with only half a screen and a few select buttons that do not work anymore.
It played fine with good sound quality, but when I wanted to change the MIDI channel it went a bit haywire…
And now it does not play anymore…
I opened the synth up and cleaned the electronics thoroughly with a correct cleaning agent, disconnected and reconnected all the connectors, but it did not provide an improvement. NO change, still only half of the screen.
Hi, Thx for the info.
I have already contacted Rainer, but got no reply. Does he still sell these spare parts ?
The cleaner I used I got from the electronics guys at the company where I work. I showed them the pics and they gave me a spraycan with a brush for cleaning electronics boards. Afterusing it, the white marks were all gone and the board looked brandnew.
Best regards,
I have a SQ-80 which is the same display as the esq1. I would try reflowing the solder on all of the connections to it. That made my intermittent display work as good as new. Might be good to check that all of the IC chips are well seated.
