@sprinklerman if you check on the test and your backlight turns on while applying the jumpers, I would think it is your power supply that doesn't get the signal to turn the backlight on. Of course you checked F101 and F501 for proper voltage as indicated on page 55. You need to let us know if you had the right voltage going to the main board while performing test #1. Your main board is usually one of the last causes of a totally black screen.
