Need help Roland XC 540

[mrsign1]

Roland Xc540 Soljet 3. Using Genuine Roland Ink. Had 110 error for encoder. changed encoder, sensor, encoder strip. Tried all the stuff I could find on the web. Changed y axis motor. Changed head carriage board and cables. I want to get into service mode to reset limit initialization. Not Possible. When rebooting it goes straight into head cleaning. I can't get into service mode. Any help would be greatly appreciated.
Thank You !!!

did you tried this?

a little key sequence of
down right left up right down left

and you're going to hold the
down right and left while hitting the power button
with your other finger

it may take several time to get there

Thank You,
I did try. I've been in protected service mode and attempted to set limit initialization

To get into service mode, make sure you do what scrip said but you have to do it within 5 seconds for it to work or it will kick you out.

Limit position is in a different mode though. Power up while holding the left, up, and right buttons.
