Cheers all. Fault not showing with incandescent lamps, I use GB LED's ( always ) Only certain lamps remain on ( dull )
which make no real sense on the matrix, so i t is a couple of diodes ( somewhere ) I was just hoping there is an EASY way to test the diodes without taking out of circuit. Or a special trick the experts use to fix.
Looks like a frustrating road ahead to amend. Bugger
