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.

For a number of reasons, both health and personal, I will no longer be active on this board. Any PMs asking for assistance will be ignored.

Never be afraid to try something new. Remember, amateurs built the ark. Professionals built the Titanic.
