- power cable
- fuse inside
- power supply - el. caps, power regulators - check output voltages
- transformer
- lose connector - reseat
- dirty or oxidized connector - c lean & reseat
- damaged OS in Eprom
- reseat all IC's in sockets
- dead backup battery - replace it
- garbage in RAM - send good data by MIDI, factory data for example

Re: [k5synth] no sound, no display... bad news I suppose...

If all Daniel suggested fails, try checking the reset circuit, I posted a sort of guide a while ago. Those reset ICs seem to fail from time to time, specially if the you have a dodgy PSU (e.g. unstable Vcc due to bad supply caps).
PS before any major repairs, try everything Daniel mentioned, as your problem is likely to be somewhere there.On 28 September 2016 at 12:19, Daniel Forró danforcz@... [k5synth] <k5synth@yahoogroups.com> wrote:
