hey guys,

i have a sony multi-fx flying around at the moment - first it wouldn't fully boot, which i solved by replacing the internal battery and initialising the unit. after 1 regular boot you could hear some sort of relay switching and it shut itself down. now you see the screen for a few milliseconds every startup, but it always powers down automatically.

checked the inside, all fuses are allright, can't spot an obvious problem...

hope you have an idea,
many thanks
christoph

Turn the power on while holding 3 keys BANK, EDIT and C

Select yes when the menu comes up
 
to initialise the unit hold down SAVE+ENTER during boot - but as i already described the error - i guess its the power supply...

any thoughts?

Can you figure out where the relay is and what is triggering it? If it's near the psu it may be part of a protection circuit. Have you checked power supply voltages?

Warning - I don't have a Sony or any expertise, just making general points,

cheers,
Ruairi
