Are you referring to the ribbon cable between the CPU and the Driver board?

Yes

It is possible that the ribbon cable is now causing lamp columns 1 and 8 to act as one. I would remove and re-fit the ribbon cable again (and even turn it around) and see if the prob goes away or changes.

I did do that a number of times but I didnt turn it around - I will do that tonight.

Back to the original lamp prob...

What does the diode measure (both measurements)?

On the original lamp that was coming on with all the others it measured something like 570 one way and NIL the other- if you need the EXACT number reading I will get that again tonight  - yes 

And what is the other diode you've found reading? Again, it might be out of spec as well...

This is the one I found in column 8 that wasnt part of the original 'row 2' issue - It was also reading 560's / 570's BOTH ways - once again if you need the EXACT numbers I will get them again tonight- yes 


Thanks so far
