We have recently discovered that the Japanese Matrix 1000 boards were early revision and had to be modified to be compatible with firmware 1.11 and 1.20 Most of the time they have an EPROM 1.03 If you notice that patches … Continue reading →

Hello fellow fedis!
Back from holidays i checked the supply voltages on the M1000.
Outputs (V)
U5 +12,11
U6 -12,16
U7 -5,02
U8 +5,03
U9 +5,03
Inputs (V)
U5 +19,45
U6 -19,55
U7 -12,16
U8 +11,54
U9 +11,55
outputs seem ok to me.
But I am not sure whether the inputs are relevant.
Battery perfectly at 3.0V but the problem persists: No sensible sound!
Not even on the 200+ ROM patches! Only some humming, some bursts...
Help & boost! 🙏🎹
I did change the battery in the end, had to undo the entire PCB and five power transistors from their heat sink, desoldered the original battery and fitted a CR2032 socket and it’s back together now

A Quick Matrix-1000 service tonight. This one got a new battery, Tauntek’s excellent 1.20 firmware update (with permission!) and some repairs to the display. Finally - reloaded the factory patches and calibrated the DAC DC offset. Done!
