I hate to say it, Sandra, but that problem usually doesn't involve an easy/cheap fix. I run a 1200 here, so I know from whence you speak. If this is an "under warranty unit", I'd box it up and swap it out.

BUT, if not, and you're any good at dis-assembly/re-assembly or know someone who is, I HAVE fixed problems like this with the "pressure" method. It worked on a Chevy digital dash that was blanking out on me and a couple music keyboards.

Power it down and unplug the power cord, dis-assemble it to the point you can see the board that feeds the display. Very carefully plug the power cord back in and power it up. While avoiding touching any of the boards or connections with your bare hands/fingers, use a pencil eraser and lightly apply pressure to different spots on that board until (maybe) the display lights - indicating a loose connection; probably a bad solder joint in that area. Trying to repair it would probably fry it, unless you're an ace solderer.

Now, the trick is to remember that spot, use a piece of non-conductive material, like a small wad of electrical tape big enough that it would apply a similar constant pressure to it at that point once it's re-assembled. I know - sounds bizarre, but I've made it work where soldering was impossible without a professional teardown.

Good luck,

I just experienced my p85 with a key problem on the F# below middle C. You will need to disassemble the keyboard and usually the keys are groups of 6 - 8 keys. If you remove the group that has the problem you might be able to find the problem visually. Mine just involved removing and reinserting the F# key back into the assembly. Then reinstalling the group of keys. If you can't get the key to work properly, you will probably need to buy the group assembly from Yamaha.

How hard is it to repair a sticking key on the keyboard. I have a new Yamaha MM6 and it's going to cost me all kinds of shipping charges to exchange it. Was wondering if it would be worth it to just...

It kinda depends on if a hammer is broke or key is broke. Or if a foreign object is stuck in there. Typically not hard if you can remove screws and remember how they go back in. TypicAlly the bottom panel comes off keyboards ( start by removing those screws ) or the top case will fold up ( still bottom of keyboard screws ) then multiple screws to realease keyboard assembly. May have to disconnect some wires/ ribbon cables so have a sharpie ready to label to ensure correct reassembly. Then it's all about if they have separate keys or a keytree or sometimes just removing ba key and reseating fixes sticking problems. Get yourself a can of blow off or contact cleaner just in case. Not sure who locally to you sell parts but you can always call manufacturer and ask who does their distribution for parts.

Hi, I need to know how do you replace the 1" compression driver in a mackie thump th-15 and where would i get one from ? cheers.

After removing the back cover disconnect the tweeter cable form the terminal. Then hold the tweeter magnet and turn it anti clock wise. The driver unit will unscrew and come of the horn assembly.
Keep the driver unit on a firm table and unscrew the four + screws. It has a sandwich assembly which will part into two if you put a sharp knife and twist. You will see the tweeter diaphragm which can be lifted up again by using a sharp knife. The replacement diaphragm is available from the below given address

Yamaha has two type keys... one is weighted with a metal counterweight and the other uses silicone domes with conductive rubber pill contacts. Those are easy as you need to clean the pills and the circuit traces they contact with Qtips and 99% isoprophyl alcohol. Then lay the sheet ovra the indexing pins and put on the white key pieces and then the black and install the screws that secure them.
The weighted ones are tricky as sometimes you have to remove some keys and put them in a certain order. There is a leaf spring under each and one needs to get it tucked up in the right place, One first has to tuck the one part toward the player to engage the switch action and then move it toward the back and engage the back pivot... not easy to describe on here.

THere are a number of keys that are stiff or "stick" and do not play properly. IS ther a simple fix?

Check if front of key is hitting the case. If it is, analyze why it is happening. If unit has been dropped this can happen. One can sometimes move the whole key assembly back slightly if this is the problem.

DJM - 400 effects Button will not turn on

IF everything else (all buttons and functions) are working, then I would SUSPECT that the actual button switch has failed.

Probably the internal guts of the button have broken and what was random was actually the parts intermittently bouncing around giving false contacts.

OFTEN the replacement of the parts require dis-assembling the whole control panel which requires a bit of expertise AND patience.

IF the button is a little switch unit, that is an unsolder and solder in new switch.. If the buttons are conductive rubber type keyboard, then it probably requires cleaning... for that you use 99% isoprophyl alcohol and Q-Tips.

Unless you are adept at electronics I would recommend taking this to a shop. Care in dis-assembly and handling of the connecting cables is a must.

Have ypt 400 first c wont play note

This is likely a dirty contact. MANY of these keys use a conductive rubber "pill" that is pressed across a set of circuit traces on a circuit board.

Dis-assemble and clean both the "pills" and the circuit traces with 99% isoprophyl alcohol.

The pills are often under silicone rubber domes that also serve to spring back the keys.

Transported Roland KR-177, toppled - pedal assy needs replacing

Good grief! FInd a tech that knows what he is doing. You can replace the plug and/or the jack. Each is a few dollars at most. You can even do it yourself. If you can see where wires went just buy new parts. They are probably available even at Radio Shack.
