I did search for the service manual but could only find people
claiming they are very hard to find and not public.<br>
I would LOVE a link to the service docs!<br>
<br>
I only found the service manual for the wave,<br>
<br>
I checked 3.3V from the LF33CV and the 5V rail from the 7805 with
the big heat sink.<br>
I also checked that the clocks are present.<br>
Tried contacting waldorf a few days ago regarding service documents
but got no response so far.<br>
<br>
I'll have a closer look at the data and address lines of the flash
memory next.<br>
<br>
Thanks for all the help!<br>
<br>
Best,<br>
Julian<br>

I guess you already checked everything round

me there are also reasons to suggest a
