there is a small green light on the main panel at the bottom just right of the PHILIPS cable output when power cable is plugged in.

everything plugged in normal i press the power button and i hear 3 clicks coming from the power relay boxes. when i press the power button off. no clicking sound.

with only the x-main unplugged i hear 2 clicks but when powered off i hear one click.

with only the y-main unplugged i hear 3 clicks but when powered off no click.

i hope this may narrow it down as like i said this may be beyond my capabilities to properly test the unit. thanks.
That sounds like the Y-sustain - Y-Buffers problem. Read the following blog entries from Coppell TV.
