  repositioning the others gave me 10.     Replacing the 2 missing LEDs then fully retored ....... 

 It no longer flickers.

  = pure arse. 

Mine no longer flickers too. But..... I wait, its an intermittent fault.

To fault find a fairly complex double sided print board is labour intensive enough. To test and fault find it while it is not powered up is usually futile.

Correct procedure is ALWAYS to leave all fantasy at the door; then make some extension fly leads to give the cluster power. That way you know if the bloody thing is in fail or working mode.

Also helps to understand the circuit

Flicker has returned.
Flicker's lowest luminescence is same as when lights are on
Therefore no flicker with lights are on.

Hi, I have read all your post, even me, on my car, the display has a low brightness, before taking it apart and replacing the burnt LEDs, I would like some news about it.
On the body of the substituted LEDs, some initials are stamped that I am looking for substitutes on the internet, thank you very much.
