Message: [QUOTE="Haddon, post: 238832, member: 20350"] Hi .I have a Technics KN1000 that was given to me.It takes about 5 minutes for the keyboard to produce the correct sounds. From then onwards the keyboard will sound correctly even if I leave it on for a day . while it is "warming" up there is audio but only static noise like an off station radio. I have replaced a couple capacitors whose ESR value was a bit low. This has not helped. while open I have run a small heat gun over all caps and IC's and diodes but it does not speed up the working time for the keyboard to output proper PWM sounds. If anyone could make a suggestion I will appreciate and try. Thankyou in advance [/QUOTE]
