This is the first time I have seen one of these chassis. Are these for a 25" tube or a 27" tube? The little board is about the same size as the ones on the k7500, but is hard soldered to the chassis and not just plugged onto it. Anyone have more info on these guys?

is that the P723 pcb??
 
I have both a 25k7000 and a 19k7000 that have the remote adjustment board. So it probably best to look up any of the numbers on the chassis it's self.
 
wells made 5-6 different types of those satellite boards for the K7000.

i have had all of them at 1 point or another over the years.

they all do different things to the chassis.

are they documented anywhere? curious what mine does. I have a small hula going on in the upper right area of my monitor wondering if something on this board (there is one cap on it) could cause that issue.

no, no documentation of any kind, thank you wells.:(

some are for a 25" and some are for a 27"

we need a pic of what you have to find out.

if you have a hula, that could be from caps or possibly something in your VR circuit.

pics and video of your symptoms are needed.

that cap on the pcb is a fourth 10uf BP cap.
 
Is this what you guys are talking about? If not - forgive the hijack.

I had an old chassis laying around that I grabbed at some point before I started tinkering with monitors. I did a cap kit and new flyback (it had cracked and was arching) but it is in vertical collapse. I'm gonna follow the sticky and test the diodes and resistors listed as likely fallout. Anyway, this chassis has the attached board that none of the other k7000s I've had did. It was just screwed in place and not wired in at all. What is it for?

those things were kind of decommissioned in the 11th hour. :p Buffett told me what they were supposed to do, but I forgot.

no, these other boards install into a header that's in front of the vertical IC. I probably have 4 varieties of them in monitors at work. I'll have to take pictures of them all someday. worth noting they're all 25", so they're not like pincushion boards. some of them have something to do with vertical deflection, others I don't really remember.

what matters is that the boards are rigged up so that you have to have them installed. I tried beating the vertical deflection one and it never worked. while I'm thinking of it, I had another where you just wouldn't have a picture at all.
 
yup, you can unscrew it from the chassis and toss it in the trash.

the only parts on it worth anything are the 2 diodes, you can use one of them in the PS section on the chassis if they fail,
and the zenier diode in several places if they happen to fail.
