[TechAssist] Serv.Menu?Re: Re: [Fwd: Help! no I/R!Re: Curtis Mathis GC3500MK (Zenith 35")pix distortion,fix]

It's a  35 inch Zenith private labeled,so I entered service menu
(menu,9,8,7,6,ent) and I get four lines of options in the first screen:
"V-709-01-1,12" , STORE CONTROLS, BRIGHTNESS and ENVIRONMENT. I select
environment and it's options are: P4,N2,N4,P2. It's set to P4. Is this
the remote private label/factory setting? And what's the correct one?(
the only other options in the next screen are : Vert.sync, Max.Vol., AC
Power On.)  PS: The orig remote was the fault,my zenith univ. operated
from across the room.Thx, Phil
