Hello,
Can a tech reasonably test and possibily repair a tv and or monitor with
just a DMM?
I realize that a scope would be a great aid in the repair process...

If it's a one off give it a go,if you want to try more get a scope
with a componant tester.I know I'm a bit old school but I did my
qualifications in the Royal Navy,5 years of slog as an apprentice{try
repairing a radar set in a force 9! swing those lamps!]
Following traces and watching waveforms can show up ripple faults that
normaly you would not find.
As for intermittent faults[the worst] you would be very lucky with a
DMM to find them.
I used a scope,frequency counter,waveform generator,colour test
gen.etc. In short for a once only outlay it was all there at hand on
the bench.Depends on how many you want to do.Gear is cheap to buy now.
Think I'm glad I'm retired I don't think I could keep up with modern
electronics changing as fast they are.Good luck
