RCA 27" TV Ch M134C Service Menu Information

[[email protected]]

Hi,
I have in my service shop, an RCA TV 27V412T chassis M134C that I can
not set the TV sound for stereo. It stays in "MONO" (on a channel with stereo
sound) . I can change the sound mode (eg. Speech, Theater, etc.). Pressing
"MTS" button on the remote only causes a display, "CATV 4 MONO" to appear
on the screen. "MTS" is suppose to allow me to select "Mono", "Stereo", or
"SAP".

I can access the sound settings, "Vol, Bass, Treble, Bal, and Sound Mode"
via Menu.

I have SAMs Photofact 5234 and know how to enter the Service Menu, but
there is no information regarding Menu 10 "Mode4", "Mode5", "Mode6", etc.

Do you know what the "Mode(s)" (Service Menu #10) represent?

Thank You in Advance, John

I hate to sound like Mister Obvious but are you sure there is a station
broadcasting in MTS?

That was the old analog broadcast system, I know there are a few LPTV
stations left but are any of them really using MTS?

I'm just saying, unless the set is seeing a stereo MTS signal on an analog
channel, I don't think you can select any other mode besides mono.
