Is it OK to superglue the key guide to to circuit board?

This is an ongoing problem. I've finally figured out the cause, but I haven't succeeded in fixing yet. The problem is that I sometimes get extra notes. The cause is that one of the key guides the black plastic strips that screw into the circuit boards under the keys keeps coming loose. Specifically, it's held to the circuit board by 3 screws and a tiny plastic pin that fits into a hole in the board. The screws hold OK, but the pin keeps popping out, whereupon I get extra notes with a particular note combination. Opening up the keyboard and popping the pin back in fixes the problem, but just for a short while. I tried replacing the key guide as well as an adjoining one with new ones from Yamaha, but it doesn't prevent it from happening. It looks like an obvious fix would be to set the key guide in place with a dab of superglue, but I'm scared that this might cause other problems. Any thoughts?

If the pin is plastic the try deforming the end bit so that it has to be pushed hard into the holes (one end only)

G# and A# Ghost Notes!


First try looking in your transpose settings. Refer to your manual to see if any arpeggiation/unnatural chord settings were inadvertently created by you or made by another user. If you believe it is a software problem you can not solve, back up your memory bank, remove your memory card, and hard reset your keyboard. Insert your memory card and check to see if your problem still exists.
If it is a technical problem, it sounds like you may need to get it checked out by an engineer/repairman. Sometimes when a digital keboard's keys collect too much dust/debris they can trigger multiple keys that aren't being pressed. Think about it like a key getting caught on an upright piano and pulling back the hammer next to the one that was played. A digital piano works off of one or several printed circuit boards or PCBs. The printed circuits usually can not short circuit because the wires and circuits sit in fixed positions. If an alien conductive fiber or series of conductive fibers connects a conducter to another, or if there is any humidity inside your piano it may cause circuits to misfire when a circuit is connected in the area. This could explain why notes you are not playing are being activated in the area in which you are playing.

If you are in a humid area and you suspect that this may be the cause you can attempt to draw out the humidity before getting a an expensive diagnostic done. Find a box large enough to house your keyboard. [If it is on a stand take it off and] place it inside the box. Cover the keyboard with plastic wrap (so as to prevent any foreign objects from getting into the instrument) and very carefully surround the piano with white rice. Remove the plastic wrap, close the box and leave it alone for a few days. The rice draws out any moisture from the electronic components. Very carefully (again so as to avoid getting any rice inside it) remove the keyboard from the box; remove any dust from the body, face, keys, and other components. Try your keyboard now. If humidity/moisture on the PCBs was the problem it should be solved. If not it is time to take your piano for a tune-up.
Hope this helps!

Yamaha pf85 14 keys not working & two of the three circuit boards look damaged.


The PF-85 action works by having the hammers strike the contact strip, which in turn connects the trace patterns on the circuit boards you're looking at together.

Any dirt between the contact strip and the circuit board will cause the keys to not function correctly. You can remove dirt with rubbing alcohol (iso-propanol) and a cotton swab. The only thing on these boards is traces, contacts, and diodes so they are safe to handle...just don't get finger prints on the contacts.

You should also make sure that the white wires are plugged in all the way on the back of these boards. A loose connection will cause the problem you've described. As would missing screws!

Yamaha psr 550


When PSR550 keys stop working, or are intermittent, in any arrangement, this can be fixed (with work). There is probably TINY dust or debris which prevents a clean key contact from taking place; you must unscrew and open the PSR550 up like a ****, then unfasten the bottoms of the keyboard circuit boards. You can figure out how to move them without totally disconnecting them. You will observe how a tiny rubber-mounted contact presses against an interleaved circuit-board connection pattern to make contact when a keyboard key is pressed. Any dirt or crud on the contact area of the circuit board must be removed, because it will prevent the conductive contact from bridging the circuit cleanly and fully. I used 91% alcohol and QTips to clean all contact surfaces. It took me a couple of disassemble/assemble cycles to get all the keys clean and working, and the PSR550 back together. But first download the service manual: it will show you how to open it and access various components. You will see that the keyboard switches are much like calculator buttons on a TI-83 calculator. They are pretty well enclosed, but you will see how much dust can settle in just through various humidity conditions, especially if you take it to gigs. Good Luck.

I Have a Marshall Amp and it had blew a circuit board that attaches to the fan so i replace the fuse and circuit board and now it turns on and registers the guitar cause the lights inside the amp go on...


It is what caused the fuse to pop that concerns me.
You did the correct thing looking for the source of the pop.However seeing any type of winding / coil that looks to have overheated is always a concern.
A small amount of discouloration is acceptable but should always be checked as they can cause much more damage if allowed to overheat and or short.
Many coils / transformers etc can be had off the shelf so to speak so I would start by getting a schematic and seeing if there is a value on it to measure against. or maybe from the coil itself.
test that first !If its OK then check the amplification stages.
Injecting a signal and tracing it is quite often a simple method to find out where the signal ends or is disrupted

Crate flexwave 120 tuner and all effects stoped working


Hi there,I have the same problem with my flexwave 120. I opened the amp to measure several capacitors on the small effect circuit board. If one of this capaciters have internal short circuit, wich will effect the others causing effects to fail. I removed them one by one to find possible short circuit. All capacitors were ok. I think the problem is in the processor wich is to diffucult to replace. I think it's easier to replace the effects circuit board. But where do we find this board??10_29_2011_6_25_35_am.jpg

Some key in my xp-50 doesn't work,same as midi signal? Rich


Since you haven't told us much information, I can only suggest you check the TRANSPOSE settings. These cause the keys to shift left or right INCLUDING the black keys.

How do I remove the keys from a Roland KR 4700 piano? We can't figure it out. Please help! I can't afford to get a repairman. I need to replace the contact strip. It's happened before.


If these are semi weighted keys here is a cut and paste from a manual:
19. Disassembling the Keyboard Assembly
* After inserting a round stick (Rod: TX000670)
between the frame and the keys, remove the
circuit boards. (Fig. 23)
19-1 GHD EBUS L, MK SUB Circuit Board
(Time required: about 12 minutes)
Remove the seven (7) screws marked [260A]. The
GHD EBUS L and MK SUB circuit boards can then
be removed. (Fig. 24, Photo 5)
19-2 GHD M Circuit Board
(Time required: about 12 minutes)
Remove the five (5) screws marked [260B] and the
screw marked [262]. The GHD M circuit board can
then be removed. (Fig. 24)
19-3 GHD H Circuit Board
(Time required: about 12 minutes)
Remove the four (4) screws marked [260C] and the
screw marked [262]. The GHD H circuit board can
then be removed. (Fig. 24)
* Keys can be removed without removing the
circuit boards.
* After removing the GHD EBUS L, GHD M and
GHD H circuit boards, and the rubber contacts
can then be removed.
19-4 Rubber contact
Remove the GHD circuit board for the involved key.
The rubber contacts can then be removed.

The rod is inserted above the weighted hammer and the bottom of the keys from one end. It appears to be about 1/4 inch diameter dowel and will run the full length of the keyboard. You might use 3 foot ones from each end.

Screws are removed and the boards removed without taking the individual keys out.

Middle c will not play -- how do I get to the contact?


If this is a Yamaha synth (you didn't say what type) often the keys are done with conductive rubber "pills" that are pressed onto fingers of circuit traces on a board under the keys.

To clean, you have to dis0assemble the unit to get at the contacts. Often th keys will have the conductive pills in silicon rubber domes taht ALSO act as the key spring.

When you dis-assemble the keys whcih are usually in groups that have many screws retaining them, you can clean the pills in the silicon domes AND the traces on the circuit board with 99% isoprophyl alcohol.

A fatal problem sometimes happens if keys have been smashed down and there is a crack in the key circuit board. The board must be replaced and can be procurred from Yamaha Parts at Yamaha America in California. The Key circuit board is usually in a couple parts. The circuit traces where the pills hit have a very hard carbonized coating.

Peavey minx 110 no sound from main speaker but headphone jack is ok. speaker wires are attached ok.everything on the board appears to be in good shape.amp powers up and all controls work great through...


Inside the headphone jack is a built in switching mechanism. It is there to cut off the sound to the speaker when you are using headphones to practice quietly. For some reason or another it seems as if this is no longer working correctly. One of the causes of this can be bad solder joints on the circuit board where this jack is located. Another cause is a failure of the jack itself. If you are capable, Take the circuit board out and have a look. Hope this helps.

G key not sounding


If it is a single key, then the key contact either needs cleaning or there is a crack in the circuit board with the contacts. These likely are conductive rubber contacts. Take them apart and clean with 99% isoprophyl alcohol. They are usually a black rubber "pill" in a silicone rubber dome that is pressed onto traces on a circuit board. Clean both the pi;ls and the circuit board. Do all thekeys at the same time to avoid having to take apart to do others later.

If ALL G sharps keys are dead, then either a wire is broken or circuit board connector or a crack exists in the board. Cracks in the board is USUALLY fatal.
