I have a Yammaha MM6 keyboard, its about 2 years old, I have used it maybe 40 times total since I got it brand new and the lcd screen on it is only showing up on the left half of the screen now, What can I do? I never even got used to how it all really works so Its really hard to navigate through the options and settings and everything else like that now with only half of the picture showing...I've been reading a lot of different posts from MM6 customers online saying that the exact same problem occurred to there lcd screen its the exact same model and problem as mine..That is really messed up that they just all happen to have the same issues right about the time their warranty is no longer in place..I worked so hard to get the money to buy this and it just stops working on me.?? Please somebody help me..

1975 - Gibson SG Special with P90 pickup (Woodstock Festival)
1976 - Yamaha SG 175B / Gibson SG Special with 3 Open Coils
1982 - Paul Reed Smith (PRS) Custom
1988 - PRS Santana II with PRS Santana III nickel-plated pickups and .009-.042 D'Addario strings

Either the keyboard is disconnected or the Keyscan on the keyboard itself is but. More than likely a loose connector.

SOURCE: I have a Yamaha YPG-525. Everything is working

I have the same problem, mine is Yamaha YPG-625. This seems to be a common problem with Yamaha keyboards. I opened the 100 screws in the back, separated the main board from the display unit which is under it if you flip the keyboard upside down, to verify if there was any loose wires, nothing of the sort.
It is so frustrating, the keyboard is working fine but it is hard to navigate because the display is not functioning. Yamaha should do a recall as this is obviously something wrong with the keyboard happenning to a lot of people

SOURCE: The LCD has lines on

The defect is likely failure of the LCD module and the connections to the glass sandwich... it is likely fatal to the module... If you are adept with tools a bit, you can probably replace it yourself... You have to go slow and be careful to keep track of where stuff goes.

One has to be real careful to not damage the ribbon cables that connect between the upper and lower shell. I suggest having two people present to handle the shell when opening it. Have a good work surface and organizer cups or bins to keep screws seperate. There will be a LOT of screws from the back to remove to seperate the halves. DO NOT force anything.

You can probably order the part... Call Yamaha America Music support and ask for parts dept to order the part... I suspect it is a bit pricey. While your at it, inquire if they can sell you a service manual for the keyboard... they used to do this for $15 and you could get one with your order. The manual for the Tyros I got is very complete showing all the internal and assembly procedure.
