Casio Collectors

Hello. I've just uploaded a copy of the Player's Manual for the DH-800 digital horn to the Files section.
 
I'm looking for the Service Manual for the same model. Does anyone have this, or at least the schematic diagram for the main pcb (M264-MA1M)? The other pcbs in the DH-800 are similar to those in the DH-100/DH-200, but this main pcb is unique.
 
Casio published excellent Service Manuals for the DH-100/DH-200 and the DH-500 models, so I would presume that there was a similar manual for the DH-800, but I can't find it anywhere! Can anyone help, please?
 
Thanks, Bruce

Hi Bruce! Merry Christmas to all!

Thanks for uploading the user manual - I've also been looking for the service manual too.

No schematic, but there is a repair guide for the squeal fault for the DH800 at the bottom of Paul Fox's DH page here, which may also have some other schematic info:

Are you just wanting the service manual for keepsake, or you have a problem with your horn?

Here is another place:

I have bought Casio service manuals off this guy before, he has the DH800 listed among his manuals - it's not clear if it the service manual or the user manual. Email him and find out - he had some very hard to get service manuals that no one else had. They're paper copies though only, not pdf.

Cheers, Graham

Thanks, Graham, and Seasons Greetings from Switzerland!
 
I actually need the schematic diagram to repair my DH-800, which doesn't have the squeal fault and all the leaking electrolytic capacitors have already been replaced.
 
On 14 December I emailed WD Greenhill & Co to ask about the DH-800 Service Manual. Since I didn't receive a reply I presume they don't have that one. I also drew a blank with manuals-in-pdf.com
 
Cheers, Bruce

Just a note to say that, although I haven’t yet found a Service Manual for the DH-800, I was able to trace enough of the circuit with the help of the DH-100 schematic to locate the fault (an open circuit pc trace). So I’m glad to say that my DH-800 is now working fine.

Best regards to all,
Bruce
