Yamaha Tyros 1 Screen Issue

[xstar]

Hello musicians,

I have problem with my tyros 1 screen. It's very bright, I mean that bright that I can't see the content for about 5%. So, I have had decided that I will buy a new screen from China. I received it today and tried it but there is no difference. Do you guys know where might be the issue? Thank you very much in advance.

Hi xstar - and welcome to the forums . . . .

I don't own a Tyros, but check the manual bottom of Page 23 . . . .

On he top of the flip-up screen is an edge control protruding.

It's the LCD CONTRAST control . . . .

The Tyros 1 is quite an old board, and it's probably NEVER been moved . . .

Over time, pots get tarnished and the internal contacts begin NOT to make good contact.

Work it vigourously back and forth about ten times. THIS should effect a cleaning of the contacts.

If CONTRAST is set too high, the screen can white-out completely (you can see nothing.)

back it off, and the image should become visible . . . .

The fact that your new display behaves the same, makes me think that the CONTROL is the problem?

Let us know what you find . . .
