ZENITH:
I think this might work on Goldstar TVs as well, since both Zenit
and
Goldstar are the same company, LG Electronics.
Hold the MENU button. The menu will come up and then after a few
seconds will go away. Now let go of the MENU button and enter
9 8 7 6 Enter
You will get a service menu that varies widely depending on model
so
I won't include a walkthrough here. The ones I tried were fairly
self-explanatory.
Problem solved. Went into the service menu, poked around some an
changed a setting named "C. Type" to 3 (likely anything from 2-5 woul
work - changing from 0 to 1 gave me stereo sound, then I got playing
set it to 5, etc). I also enabled the stereo/SAP (a default choice,
think, for the audio) and the audio mode setup option (was previousl
missing from the menu). While at it, I adjusted the picture size s
things aren't running off the bottom, etc. Looks like a former owne
went in there and screwed it up.
I'd be interested in a more thorough accounting of the service men
options. There are things in there like "3.58 T", "WhComp" (whit
compensation?), "6 Keys", "Scroll" and "5 Jacks" (which I couldn't see
to set) that I'm curious about.
After changing the options in the service menu, I had to rescan th
channels before I could power the TV off.
I can't select 0 (or 1 or 2) to tune to the video input, but using th
channel up/dn button lets me come round to it - makes me happy!
Thanks for replying to my original request folks - I appreciate th
helpful thoughts
