Yamaha Clp 560 does not power up.

I may have, inadvertently, left it on. Now it shows no sign of life. Fuses look good. Burned out power supply? Any help greatly appreciated.

    I have a similiar problem where the Zoom H4 does not power up even when replacing the batteries.

Without power to the unit no sound should be generated. Make sure there are no other connections.

MAYBE you have a wall transformer behind it that is buzzing. MANY wall transformers develop buzz.

Another source is flourescent lights and even some of the low voltage halogens have noisy transformers in the base.

Hi,

I had checked the fuse for the heater circuit and found that while it was testing on a low ohm check meter - it was not sufficiently handling the
full demand of the circuit - I put a bypass on the fuse and found the problem. The fuse appears to have been previously replaced with
a type not original - the original was a ceramic case fuse 10A.

I appear to be operational

No sound on my Yamaha Clavinova CLP-311


Try these steps:

  • Perhaps inadvertently, there is a MIDI settings are changed.
    Setting LOCAL-ON must be in the ON position.
    Do this (see Figure 1):

  • Connect AUX OUT (at rear panel) to an external amplifier. If the sound is heard, the damage was CLP311 power-amp.25893993-xykdzr1cdriwl1tmr4ngy0qt-3-1.jpg

Does a Yamaha clavinova clp 760 have a fuse that may need changing


There are a number of fuses on the main power board ( by transformer ) the sizes differ depending on the country of use but are clearly marked on the board.

REMEMBER TO UNPLUG FROM THE MAINS BEFORE OPENING - if in doubt seek the advice of a qualified electrician

Model Yamaha ME-50 no power


John
With AC power off.
Use a meter (on Ohms scale) to check internal fuse for blown (open) fuse.
If you feel qualified & safe with AC Power On.
Check input to internal power supply on AC Scale (Caution when AC is on) for volts in.
Use meter on internal Power Supply for "probably" DC volts leaving internal Power Supply electronics to power the rest of the electronic circuits.
Switch mode power supplies can break down. They stop doing their high frequency switching so they don't convert AC to DC.
If this P/Sup is a separate box or circuit board, inside the unit, then it can have a part number & be replaced.
Good Luck

Light is dead all fuses are good.. Maybe bad transformer ?


Probably NOT the transformer as most of these have switching type supplies. A Chauvet unit I have would not light and the problem was the socket for the Halogen bulb. The socket had burned and the contacts were so burned they would not contact the bulb. Worse, you can't even see the problem as the socket is ceramic and has a mica like cover. Replacement of the socket fixed the problem. In the Chauvet unit they had a very cleaver lamp power supply. That threw me off because there was no voltage at the socket... until I put the Oscilloscope on it... then there were tiny spikes. It turns out the supply sends tiny spikes out and IF the lamp is there and contacts are good, the supply senses the load and the feedback starts driving the supply to full output. I wasn't able to see the burned contact until I uncapped the socket. Just maybe you have a similar problem. These 250 watt Halogens with the tiny pins carring 11 amps just are ******* the contacts in the sockets.

My Yamaha Clavinova CLP-350 lost all sound. Prior to this, middle C started to have a tin-like sound. I live in South Central PA and can't even locate someone who repairs Yamaha keyboards within 50...


Here is service manual for CLP380 which should be close to your unit.

Scroll down to get manual and click on it to download. Ignore other download links.

First thing check your power supply voltages.

Yamaha clavinova clp 200 - ear phone jack slid


The control panel hinges upwards and you have to move the keybed back a bit to get at the jack. All the screws on the bottom for the keybed. I'm not sure where the ones for the control panel are.

Replacing contacts on clp 170


Unless the rubber is worn, first try cleaning the contacts with 99% isoprophyl alcohol as well as the surface they contact.

Realize that conductive rubber contacts do NOT show real low resistance when closed... the electronic circuits they drive don't require low resistance. You may find resistance up to 1 K ohms.

Yamaha digital piano clp 170


This is a common problem with Yamaha keyboards. The problem is caused by worn-out rubber contacts in the keyboard assembly. In my old Clavinova CLP-500, there was one long rubber contact strip under the keys with two parallel strips of semiconductor material. The Clavinova circuitry determines key velocity by measuring the timing between when the key hits the first and second strips of semiconductor material. The harder you play a key, the less time it takes the key to hit the second semiconductor strip after hitting the first.
After years of playing the keyboard, the keys eventually cause tears in the semiconductor material and this messes up the timing measurement for key velocity. The only solution is to take the keyboard apart and replace the rubber contact strip with a new one.
I got rid of my CLP-500 four or five years ago and got a new CLP-170. The CLP-170 is now having exactly the same problem that the CLP-500 had. Yamaha has re-designed the rubber contacts in the CLP-170 so that there are now eight individual contact strips instead of one long one. The problem is essentially the same, though. You have to take the keyboard apart and replace the worn out rubber contacts.
Here are the part numbers for the rubber contacts that need to be replaced in the CLP-170: V8286600 Rubber Contact, 12 keys, D-C#   Qty. 6 V8286800 Rubber Contact, 11 keys, A-C#   Qty. 1 V8286700 Rubber Contact, 5 keys, D-C   Qty. 1
I suggest you also get a copy of the CLP-170 service manual, part number 001677. It has descriptions of all the steps necessary to take the thing apart and put it back together again. You'll also need a "rod" (which is just a long dowel), part number TX000670. Before you take the circuit boards off the keyboard assembly, you have to insert the dowel between the keys and the frame to keep the keys from falling back and getting in your way. A 5-foot long 1/4-inch dowel will probably work. (I haven't yet taken apart my CLP-170, and I don't have Yamaha's "rod," so I'm not sure if 1/4 inch is the right size or not. I'll report back here if it's not.)
Good luck, Howard
