Alright, well, I went back and rechecked the LED strips (individually this time), and one strip had a bad (but working) LED....8vdc dropped across it. I didn't notice it the first time around cause the whole array worked.

So thank you all for your help, I did learn alot about the power board circuitry which will be helpful in the future!

Glad you found the culprit, was a good refresher thread for me too, was able to put that backlight testing back into my memory, it fell out, hope it stays in longer this time.
