M2929D1 Symptom Dead:
Location D15, 31DF6 Shorted.
Vertical issue..Small thin lines at top of picture
with alittle bend on each sides.
C68 10uf 25v's
Also issues with C87 after warmup a Mylar cap .47uf 63's needs to have
a higher voltage atleast 100 or more.
M3129DB1
Symptom: Dead
Tip: if you got one that works, Go to it now and redress the Anode wire
or it will short out to the yoke and burnup so many parts.
The list is long!! Can use heat shrink tubing if needed.
Or coil it up to the crt away from yoke.
found small cuts in red wire
Most anode wires are laying aganist the yoke and HV gets to the yoke
and you can guess the rest.
Fly,Hot,Resistors,Vertical ic,yoke coil..
Just forget it,Buy another brand monitor!!
M3125
Symptom Dead:
Shorted HOT
Q36 Bad Flyback..Etc
Still waiting on fly!! Back order!!
Just forget it buy another monitor..
Yokes are different on all model's and version's chassis
when i get time i will measure the ohm's and post it.
