Title: Monitor ID/Wei-Ya Chassis Replacement (WG-K7000)
Post by: keeganhayes on October 16, 2011, 10:20:44 pm

Picked up an empty TMNT for $5 which I'm in the process of converting to MAME!

The chassis was busted to hell, so my project for this week is getting a new one installed:

1) I think I correctly identified the monitor as a WG K7000. (It has a Zenith tube) Could someone confirm? (If it makes a difference)

2) Forum member Windmill was kind enough to ship me a spare slightly-defective wei-ya chassis. I replaced the Horizontal Output Transistor as he described in this thread: http://forum.arcadecontrols.com/index.php?topic=111904.0 (http://forum.arcadecontrols.com/index.php?topic=111904.0)

3) I think I have interpreted the connections from chassis to tube correctly, could someone confirm?

This is the old chassis which I believe to be a WG k7000:

The replacement Wei-Ya labeled to the best of my ability:

I think this is the degauss cable which is connected to #1 on the Wei-ya? :

This yoke plug is connected to #3 on the Wei-Ya ?

This wire is flat and wraps around the length of the picture tube. Is this for grounding?

4) How would one go about making a vga breakout cable for a wei-ya chassis? (As I understand, the wei-ya connectors are slightly different from the conventional connectors found on ultimarc and others breakout cables)


I'm sure I've made a mistake somewhere, so let me know where I'm going wrong!

Thanks for any and all help!

Keegan

you look to be all corrct to me,the flat wire(ground) connects to the single header pin on the neck card

everything should be plug and play

Looks like your original chassis was a K7000A.

Your Wei-ya chassis will need to be "Americanized" as per my thread:

Ken, if I'm hooking this up to MAME via a VGA breakout is it entirely necessary to replace the video/sync connector? Is there some way to splice a VGA to be accepted by the current connector?
