Wrong assumption. Monitors are usually very very simple fixes; even if you
throw out the hard ones, you are still way ahead learning to fix your own.
I would start with the G07, learn the cap kit, learn how to spot and change
a bad flyback, and learn what solder connections should be redone in the
vertical. That small bit of knowledge will enable you to fix around 80% of
your G07 chassis; as I said, even if you junk 1 in 5 because you dont want
to take the time to pursue harder fixes, you're way ahead and in addition
will have the satisfaction of learning some repairs.
Next easiest (again, in my opinion) are the Sanyo chassis used in Nintendo.
A surprisingly large percentage of failures are due to a single 10uf 160VDC
cap in the vertical, which can be bridged without removing the chassis and
cures the shrunken top with the retrace lines in the picture symptom.
Another common one is the caps and transistors on the audio board failing
and taking out the sound.
Look into learning to resolder the daughter board connectors on the WG4600s
and you will fix around half to 2/3 of the ones you run across; do the cap
kits while they are apart and you should be able to fix 3/4 of them/
It would be worth it to learn a few repairs; parts are cheap, and if you are
careful you can be sure you get a quality job. Try not to get discouraged
with your first few or few dozen repairs - once you get the knack of
learning how to learn the repairs knowledge will come quickly. Email me for
specific problems if you want to get jump started on a few.
