Does anyone know how to fix a key that keeps sticking on my Yamaha P515? G3 plays but then is slow to return to the normal position - it seems kind of sluggish. It probably needs lubrication but.....I don't know how to open it up Anyone out there done this before?

I haven't opened my P-515 units yet. But I do have a back-up plan involving this vid here for disassembly.

Thanks I'll check it out after work tonight....still would like to hear from anyone who has actually done it already though

    danno858 Most welcome! Me too. Although - that guy has actually done it. He opened up his P-515.

    I'm 'living' to get my chance to later open up a P-515 or P-525. I had been collecting various lubricants - for that occasion. My fingers are itchy right now to get an excuse to open one up! These are the lubricant choices I have so far. Other people 'swear' by their own types used though - but I'm going my own direction.
