Hi!

I'm new to the group and new to using Emax. =)

I received an faulty Emax 1 rack from a friend for about a month ago. It was shown (with Jammies help here on the forum) that the Echip possibly is dead, but there is a chance that a calibration can solve the problem!?

I do not like to wait so I bought an Emax 1 SE keyboard a week ago. It was, according to the seller fully functional but has been damaged in transit.

The damages are: 
1) The display is dead. In the ad for the emax keyboard the seller described that E-mu factory had repaired the display which generated a noise (Inverter replacement?)
From what I recall, Ted Summers said something about when the display is dead the Emax won't start. Maybe it's the LE Foil that's not working? But shouldn't one be able to read any characters then? The Emax rack's display is working. Well, the characters are shown but with no background light. 
I rather switch to a VFD but it seems to be a little work with that. Is there a replacement display to get somewhere? I don't wanna solder too much. 

2) The keys Ab (third octave) to Db (5:th octave) generates no sound. However, it works to connect a MIDI keyboard to it and trigger all the notes. A funny thing is that on some sounds (loaded from disk), the D and Eb (5:th octave) generate sound but the voices "hangs" In most other sound banks they're dead as the other ones. It seems that only sounds with long decay, sustain and/or release are generated from the 5:th octave D and Eb. 
E, F, G #, G (5:th octave) do not work but the last A, A #, B is working. 

Any ideas? 

Regards
Kalle

  My friend replaced his displays with led lcds from crystalfontz.  I can't remember the exact ones and I think it may require a little work, but they look really nice and they're pretty cheap (I think around $20).  I can ask him for the part number or dimensions if you like.

  Ok. It seems like there is much more space between the display and the pcb on the keyboard. The vfd should fit on the keyboard whilst the oled at 9mm will fit the rack version "better"? I read that you need to replace the thing on R7 to R8 and cross wire PIn 3 to ground and whatnot in some cases. Happy if I could avoid that. 

  Thanks!

I put the VFD into my emax rack without any trace or PCB cutting, I just

  Thanks for the quick reply. 
  Can I fix or get those diods fixed somehow? 
  It's not a big deal since I have a MIDI keyboard to control it with. 

  The display doesn't cause any noise now since it's not working =) 
  I guess that the inverter is broken but I will check with a multimeter tonight.

  I guess I go for the VFD then. =)

  Great Jammie. Where do I send the board?

  Ok. So it doesn't matter if the keyboard has the SE upgrade and the rack doesn't?

I put the VFD into my emax rack without any trace or PCB cutting, I just

Yes it does press a bit when tightened, but the buttons seem even on mine, 
perhaps 1 or 2 mm are harder for me to gauge, I'll check, but I suspect you 
are right.  Still preferrable to me than doing irreversible mods to the PCB, 
if I broke it I'd have to send it to you jammie!

  Ok. This is what happend! 

  I pulled out the mother board of the SE keyboard and put it into the emax rack. 
  On the emax rack startup the top row in the display showed black blocks. I had put the IDE(?) cable to the analog board wrong. After I changed its position the emax rack turned on, loading emu software and generated a loud noisy, crackling sound which faded away after 10-15 sec. Then when I played some notes same thing happend as before but this time very loud noisy/crackling sounds. Then it stopped generating anything at all. No sound. 
  So I switched the rack off and just for fun switched places on the left and right audio cable. On startup it generated this ugly noisy, crackling sound but the software froze on the message "Loading software". I switched it off and reassigned the audio cables. Now it loaded the software ok but no sound. No noise no crackling sound.
  Then I pulled out the analog board from the SE keyboard and put it into the rack. Everything works well now on the rack. 
  The strange thing is that when I put the exchanged analog board into the keyboard and turned it on... the display woke up? And when I look at the rack's display...it actually have some shimmer. Don't think it was any shimmer before but i might be wrong. 

  The SE keyboard E-chip differed from the rack's E-chip. The SE E-chip had a piggy back thingy on it and the rack didn't. I've got some pictures of them if needed. 

  So... do you think it can be the DACs?

A funny thing is that on some sounds (loaded from disk), the D and Eb (5:th octave) generate sound but the voices "hangs" In most other sound banks they're dead as the other ones. It seems that only sounds with long decay, sustain and/or release are generated from the 5:th octave D and Eb.
