Sorry.
I said "nothing looks fried to me" but I meant that all readings are normal
(I have monitor's schematics). It sure isn't in my nature just to look
inside a broken device and say that I have done all I can do to repair it.
But ok, you don't know me.
It is like taking your car somewhere, and telling the mechanic, the car has
a rattle, and does not start!
I'd say it's a broken bearing in the ignition system and must be replaced
(I would tell you that if I was the mechanic)
Speaking of my monitor I'd say it's probably power transformer T603, looks
suspicious. And I think that the transformer is the source of strange
"buzz" sound.
If you are not trained and equipped to do monitor service, I would suggest
you give the monitor out to a service centre for a proper estimate.
I admit that I haven't got training nor proper equipment to do complicated
monitor repairs (I did several simple repairs, tough) but I tought that
maybe someone here has already encountered simple malfunction on this
monitor and knows what to do. So this group is my last stop before going to
a service centre and spending 50$ for the repairs.
