This should be interesting
lilshawn:
vertical collapse...either the TDA chip or the resistor feeding power into it has gone open or out of spec... or both. (usually the vert chip fails, goes shorted output and overloads the resistor, blowing it open.
Mike A:
Vertical collapse is one of those failures you are kind of glad to see.
Straight forward problem.
Now I have a D7700 with a bad flyback.
Is there a source for those?
Mike A:
I tested all of the monitors.
out of 16...
1 has vertical collapse
1 has a bad flyback
1 works fine, but has a chewed up anode wire. It needs to be replaced.
3 of them have tube burn that I consider bad. They will need tube swaps.
Not bad for 200 bucks.
bobbyb13:
With all those good spares it sounds like you should be building something!
I really wish I knew where to begin with fixing chassis.
I know what lilshawn said was english and useful but it may as well have been written in cantonese.
Mike A:
Hehe.
We all start somewhere.
lilshawn knows a lot more than I do.
I am just removed the anode cup and I am going to pull the chassis and throw it on my bench.
