Jerry, changing the customers remote to a service remote in this case 
worked out just fine, I can turn the set on from the front panel power 
button then press wake-up/sleep on the remote and the service menu pops 
up with the number "2" in each corner, "8b1-0.16 A2" centered in the top 
1/2 of picture and "09" in left center of lower 1/2. My problem is 
figuring out how to navigate and make changes. Is there any possibility 
you can email, snailmail, upload, fax, or whatever, the adjustment 
section of the service manual? Maybe even the whole thing in case I need 
to trouble shoot instead of adjust?
Thanks,
