I wonder if any of you could help me with this DX7 mk1 problem.
It har the grey matter E! card installed.
When I turn the DX7 on it works fine fro 5 to 10 minutes. All of a sudden it stops making sound and behaves like I was moving the data slider fast ut and down. If I reboot the synth it still has the error, but if I let it cool down before I start it it works for a couple of minutes again.
Both slider are bad. Volume maskes a lot og noise and the data slider is a bit unreliable . I will change them out. I thought the the problem was caused by bad connections in the data slider, so I desoldered the slider and use the + and - buttons to navigate. But, the problem persists.
It might be a temperature issue, but I don’t know where to look to find errors like this.
Any hints and tips are mush appreciated.
