I dont understand the point with the "yellow crossed component" next to the Led drive ic. Three of the ends are still in yellow, and one point is marked in red and connected to the other side of the mainboard on a special ponit.

The yellow massage in the picture says "this yellow track not connect change led coil".

What do you mean by that?

Is it right to connect the red marked point on the coil with the ponit on the mainbaords backside?

I'm very sorry for all the questions, but i'm glad that i have found such good help here!
I'll tell all my friends about this forum.
