Re: [vintagesynthrepair] Cetain notes not sounding on JX-3P

Temperature COULD be an issue, however equipment is may be subjected to temperatures colder than 2C while being shipped from one place to another in the winter. What's more of a factor is condensation which may form on anything which is brought from a cold to a warmer environment. If the temperature of the equipment is lower than the dew point of the environment, moisture can form, and may cause anything up to direct shorts in circuits when powered up. It's a very good practice to ALWAYS let equipment warm up to the temperature of the room before plugging it in, so as to allow any condensation which may have formed, to evaporate.

It is the low E, then the next up C, then next up Ab, then next up E, all 8 semitones apart.

When I brought the keyboard out of the garage into the warmth, after a 20 minute warm-up, the problem
disappeared.

Right now all the notes work, can temperature be an issue? It is only 2C in the garage, I keep the gear only so it does not freeze.

do you suspect something else?

Is it like every 6 notes or 8 notes or entirely random? It could be just dirty contacts.
