I have 2 27" 9200 series monitors and 1 chassis.
1 monitor and 1 loose chassis are D9200 I am betting as they both have D9200 printed on the board.


1 monitor is what i believe to be a D9202 as a printed sticker on the chassis says 54A9202 and a sticker on the frame says "Safety Model No 27D9202"


My problem is I only have ONE Video/Sync Interface Board that only fits the connectors on the D9200 monitor and loose chassis so I assume they are not interchangable with the D9202.


First, can anyone tell me a part/PCB number for the Video/Sync Interface Board for the 9202?
This monitor, unlike the 9200, has a bonded yoke, and no convergence rings if that's any additional help.


Second, the 9200 monitor I have has a non-bonded yoke with a retaining clamp, convergence rings, and convergence strips.
Unfortunately, the plastic on the yoke that holds it to the retaining clamp is completely broken/separated and the yoke is just flopping around doing its own thing.
I assume this yoke can be replaced (assuming one can be found.)




Here are the numbers I could find on all the things I have, I'd appreciate any info on these that will allow me to test/repair the 9200s and find a Video/Sync Interface Board for the 9202 (to test/repair)

  • I break stuff...then fix it...sometimes
generally the last part of the WG numbers denote a particular tube size/shape/configuration.

the ACTUAL part number that you should have on a label somewhere for a D9200 should be WGM2792-XXXXXXX (the X's part will vary depending on how or where the monitor was sold usually being something like U0TS30A or U0TS42A. these denote things such as the monitor being part of a a bulk factory installed monitor or sold as a loose item from a supplier)

most all chassis parts across all the 9200 series of the same size are interchangeable... as the 27 and 33 and 39 inch versions are all slightly different in the deflection board area.

there is a slightly different end of run version of the 9200 (basically a pre-9400) that is labeled as a 9200 but shares more of the 9400 design with improved resolution capabilities (800x600) it's basically not documented and i've only encountered it once... and I would prefer never to have to mess with it again. it's possible your weird chassis could be this.

as for the yoke, it's a common thing. they weren't quite tuned correctly and end up running really hot in some resolutions and bake the plastic until the plastic gets brittle and disintegrates. i just goop them up with clear silicone and line them back up. i highly doubt you'll find a decent replacement yoke, as they ALL did it. that's why they switch to the bonded type yoke on later models.

funny. i guess I should have checked my post first but it had gone a bit without a reply.

I literally just sent you a PM before seeing if anyone responded to my post here.

I think i'll give the broken yoke monitor a try and see what happens.

Then i'll cut the wire for that video connector board and make an adapter. between the 9200 and the 9202.   
worst that can happen is I will still not have a since working monitor.

thanks.

Thanks

let me have a dig though my chassis i might have one.

can you link me a picture of the one you have, and i'll see if i have the OTHER one.

(EDIT nice formatting on the pic idiot.) oh well you can still read it.) this is one i have... its made in korea.
