yes i have a non responsive button on a Yamaha PSR - e433 , and was wondering if anyone had some input ?
Hi, Hopefully the Yamaha PSR-e404 is just a variation of the PSR-e403 as it is not listed on this Wikipedia list of Yamaha models. (I realize that it may not be accurate- scroll down to PSR-e models). https://en.wikipedia.org/wiki/List_of_Ya… Here is a link for the service manual for a PSR-e403. It has all the usual information found in a service manual and it also details how to dis-assemble it. Hopefully it may be of some help. When you open the link, written beneath the document preview box, it will say ‘….. downloadable free of charge processing ‘. Wait until it says Get Manual. Then you will be able to click on it (Get Manual) to download. http://elektrotanya.com/yamaha_psr-e403…. Update (04/13/2016) Hi, Cannot find the service manual for a PSR- e433 but others online have said that a PSR-e423 is very similar, so this may be of some help. The conditions to download from the site are still as above. http://elektrotanya.com/yamaha_psr-e423_…
