I'm trying to assist a friend with an old Magnavox CCR190AT03 TV/VCR
combo. Can't receive TV channels (all channels just display blue
background), but can play VCR tapes.

My inclination would be to go into the menu functions to verify the air
vs.cable setting, re-autoprogram the channels, etc.; however the
original remote control has been lost so I can't use it to access the
menu functions. A generic universal remote works for the on/off and
channel control, but its "menu" key doesn't seem to bring up the menu on
this set. Based on a recommendation from Magnavox' customer support, I
tried accessing the menu by pressing both the channel up/down keys
concurrently and then tried again by pressing the volume up/down keys
concurrently, but those combinations didn't work either.

Is there something else I can try, short of purchasing a new OEM remote,
to get into the TV's menu functions? I don't think I need the service
menu, just the normal consumer operation menu.

Thanks, in advance, for any suggestions.
