I've got this Magnavox 15MF050V/17 LCD TV/VGA monitor.
Has two tuner modes AIR and CATV. Has one RF input.

In Air mode, the setup mode automatically scans
the channels. It properly recoginzes local VHF and UHF channels
EXCEPT channel 10. It sets up channel 11 with a blue
screen. If I manually force it to channel 10, I get
a black&white picture with a lot of noise in the sound. Can't
find any way to tweek the frequency.

In CATV mode, it properly scans and programs all the VHF channels
including channel 10. Channel 10 picture is great.
But it won't get any of the UHF channels.

The symptoms suggest to me that the tuner is ok?
But I have no idea what's going on or how to fix it.

Suggestions?

Thanks, mike

What's your program source -- antenna or cable? Do you have another TV
for comparison?

In CATV mode, UHF refers to channels 37 and up. 14-22 ate "midband"
between broadcast channels 6 and 7, 23-36 are "superband" between
broadcast 13 and 14.

Cable providers often offset the channel frequencies to prevent
interference with broadcast signals. They may also map channels to
different frequencies altogether.

With the tuner set for CATV, you should be able to receive over the air
signals, with UHF channel numbers remapped as follows:

Broadcast 14-43 -- add 51 (14=cable 65, 43=cable 94)
BroaDCAST 44-69 -- ADD 56 (44=cable 100, 69=cable 125)

Channel 10 is PBS...violent indeed...
But it works fine in CATV mode???
And there's nothing in the parental controls menu indicating it's
enabled???

For the moment at least, in the US most of the major network
stations--ABC, CNS, NBC--are on the lower (channels 2-5) VHF channels.
