My Yamaha psr e303 all keys from bass side stop playing what can I do?


You might have the accomp switch turned on?

If not try holding down the highest key whilst turning the keyboard on, this will start a factory reset.

Yamaha YPT-410 When playing the keyboard, the sound cuts out when playing multiple keys, and then begins again only to cut out again. Does not matter which keys. I have done a factory reset and it did not...


It's probably your keyboard. Some keyboards are limited with it's polyponic capabilities. Some can play many notes at one time, some cut out when it reaches it's limits. Check your manual for specifications.

My Yamaha PRS-293 will not play any of the E keys or the Bflat keys. I reset it once (power up while holding the highest note key) which fixed it once. Now it won't fix it. The MIDI plays all of the notes.


The key switches are scanned as a matrix. One of the matrix wires has broken or connector/cable is not making it... It will be a connection in common with the non-working keys.

Here is schematic:

http://elektrotanya.com/yamaha_psr-293_sm.pdf/download.html

On page 40 on the board labelled 61H-MK and the connector DMLCD-CN401 the connections to pins 11 and 12 with signal names N14 and N24 have become broken or disconnected before they get to the processor board.

Since these lines are NEAR an edge, the cable could be not quite in the connector at one end or the other. These two wires are what triggers the E and the A# key signals. There are TWO contacts per key as one closes first then the other... this is how they measure key velocity.

Keystation 61 key won't play


Most of these use conductive rubber pills that are pressed onto circuit board traces by the keys.

Clean the board AND the pills with 99% isoprophyl alcohol and QTips.

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.

Do a factory reset. Refer to page 79 of your owners manual.
