Dashboard with dark pixels
 

Hello guys,

everytime I ride I see the dashboard at the bottom left part of the screen with a black area.
Talking to my YAMAHA dealer, they say it MAY be due to humidity that filtered into the screen of dasboard,.....when spraying for clearing dust of just rain....but they are not sure. No solution offered but replacing it....
Just to say that the dashboard is fine, all functions work, it is not broken and has no cracks or crevices...
Any idea to clear the problem --?

Here's the link to see the problem with my dashboard.
Picture is not very good but you will see what I am talking about. Black pixels affect clock digits only,,(:angry4:by now......)

Thanks in advance for your comments.
