Where could I find a manual (not for fixing, just for finding out what all the buttons are for!)?

I have had some success by coating the contact strip contact points with conductive glue. How long it will last I'm not sure. The strips themselves appeared undamaged. My on button works easily now but I still need to turn it off the wall. All the best. Lam.

Hi, try to find how to reset it or go to default mode,find out in the users manual.Hope it will solve your problem,

NOT a fuse... thaat person knows nothing. There is something wrong for sure. Check if one of the buttons or keys MIGHT be stuck down (depressed). Sometimes the units check that all the control buttons are up and they don't really tell you why they fail to start. Beyond this a repair shop is in order.

Check the power supplies... beyond something pretty simple you won't have much of a chance of fixing if it is on the main board. Technics is really out of the business for the most part... they are a part of Panasonic. Expect to find voltages of +5 and +/-15 volts.

You can download a service manual for a KN6000 here and just MAYBE find enough simularity:

Scroll down to the "Get Manual" and click on it to start the download.

Read and understand the manual. You might also find a video on YouTube explaining part of this.

I could not find a manual for the footswitch... USUALLY the details are covered in the amp manual it is connected to... and the only issue is if the particular footswitch is compatible with a particular amp.

Here is the manual if you don't have one:http://www.mackie.com/pdf/archive/cr1604_om.pdf. There are solo buttons for each channel. There is also an auxiliary return solo button. There is also a solo to main button. These buttons are all inter related. Is your main output mute button in or out? Read the manual carefully as there are a myriad of combinations you can use. Have a look at the trouble shooting guide on page 21. If you can't find a solution try contacting Mackie. Let me know if this helps.

The only advice I can give you is to join an organ forum and post asking for a manual. Otherwise you will have to pay for one. The best source I can seem to find is through:http://mitatechs.org/node/385 or here:http://wdgreenhill.com/manu/wurlitzer_a.htm and they don't list a service manual for that model. Sorry I couldn't be more help.

How familiar are you with schematics? I've just found my CT-670, There where marker marks on the keys. I cleaned it up. I took it apart as one channels had no sound. I love this machine. I want to find a manual for it also schematics would be very helpful for me too.
I would suggest looking inside for burns on semiconductors. or loose soldering. I need to replace a chip that has no cross reference... that I've found yet... I think it's an amplifier but need to spend more time on it....
