Subject: Re: [korgpolyex] Re: Poly 800 Mk1 - new EPROM

From: Marcus Wilson <JB@...>

My three polys were all non functional when i got them, due to faulty components in the power supply circuit,

once this was rectified they all powered on with the 11 P powerup display.

if you have a battery on the motherboard, it may be low, and the memory may be corrupted,

you could try removing the backup battery and let the system totally power down for a few minutes, then re-connect the power supply

if you get 11 P then the issue is to re-load the presets

if you dont have 11 P then i am thinking there are problems in the power supply stage

as asked before, what do you mean by wierd display

Poly 800 mk1 doesnt support sysx dump ( until mk3-) ). May be would it
be similar with tape data loading ?
But I suppose it is not only sound-program lost. It looks like more
serious thing - may be mentioned power adjustment...
