OK lets go again. I understand all of the above but my problem is that on start up my slings GI are coloured and various gi are coloured during the white test.

Any advice on how to diagnose this fault would be nice.

I have experienced the flickering lights which was a small board that I replaced but I didn't realise that the GI was funky until I fitted the fluorescent sling protectors and noticed a difference left to right in lighting.

Thanks in advance for any advice to fix I have only had this machine for 1 month and it is one of the best I have played so want it to be functioning spot on.

thanks Paul

Thanks for the info but when I test each board as a single led the light actually is white and seems ok but when in the gi test there are some of the GI that are pink blue and yellow as you can see.

Would I be right in thinking that it could be the first ng board in the matrix that causes the rest to go funky colours??
