I need to replace a speaker on a Yamaha YPG-625 88 note digital piano .....is this the same thing I should do like the piano you are showing on this web sight ? Also the big screen in the middle of the piano that says what tone you select and the drum patterns is sorta kinda going out ! could it be just getting dirty and need contact cleaning ? The place that sells these Yamaha pianos said they would have to send it away to have the repairs done and the cost would be OVER $500.00 ! Any help would be greatly helpful !
