Kana Posted October 28, 2015 Share Posted October 28, 2015 The 3rd highest B flat key does not play correctly - the sound does not last as long as the other black keys and sporadically, it will emit a high pitched sound that's ear piercing! We have reset it to factory settings and it didn't correct the problem. I contacted tech support and they referred me to this forum. Any ideas on how to fix? Thank you!

Brad Saucier Posted October 28, 2015 Share Posted October 28, 2015 Unfortunately your PX-150 will need to be serviced. Are you located in the US? Quote Link to comment Share on other sites More sharing options...
Jokeyman123 Posted October 29, 2015 Share Posted October 29, 2015 Wow, never heard this one! Since its only the one key-it is remotely possible something is contaminating the key contact underneath and somehow mis-triggering that note. Try some compressed air around the key opening. But I agree with Brad, this sounds like something that needs to be serviced. Quote Link to comment Share on other sites More sharing options...
