Sony Trinitron WEGA Service Menu - Experts ?

Hi Folks.
I was tinkering with the Service Mode of This Sony Trinitron TV.
Adjusting the geometry and center the horizontal and vertikal.

All good.

But what are those things in the "service" menu ?

PEAK-Freq and SCO ???

What are they doing ? i cant see any difference and what should there value be ?
(i got this TV used and the original settings are lost)

So, are there any TV Experts out there ?

What does Peak-Freq and SCO do ? ; ohh and sometimes the TV switch to 16:9 in the middle of a game (only on SNES so far)

Any Ideas ?

Thank you guys

First take note of the specific model of Trinitron your TV set belongs to (and build year). Then try googling the service manual.

Gee, that must be unpleasant . Is your video cable true RGB scart ? Does this happen when plugging your SNES on another TV set ?
SCO probably means something like sub-picture color or contrast. I am no expert btw, merely an enthusiast.

Thanks for the infos
Yes, that is unpleasant if the TV switches all the sudden to 16:9
This SNES RGB cable is crap (amazon rubbish) , a handmade SNes RGB Scart cable is on the way

I only have this TV for testing, becuase i would not want to rip the SNES out of my Retro gaming setup and to test that problem on my Flat TV would not make sense, i guess.

Looking forward to the new handmade RGB cable. The guy is known for his outstanding work

Nice to see that you are enthusiastic

Thanks and greetings to france
