Wei Ya monitor help

[char1ie]

Greetings all,

I have just bought a Wei Ya 20" monitor and chassis. It didn't come with any instructions and I wonder if you could help me connect the two.

There are two pairs of wires from the monitor yoke. Yellow/Brown and Red/Blue. I guess these are horizontal and vertical and connect to the connections that are marked A B H V - but there are two rows of four pins here. Where should these connect?

Also there is a big cable round the monitor with a red lead coming off and a magnet ring. Degauss?

And a black cable coming from the bare wire that hugs the monitor.

Any close up picture of a Wei Ya 20" showing connections would also be really useful.

Thanks all,


Charlie

This site (which recently disappeared) had step by step photos and instructions:

Not everything got on the archive so many of the pictures are gone. I don't know what happened to the site owner as the site disappeared over a month ago. He sold plenty of the Wei-ya chassis on ebay so it might be worth checking his ebay store.

The only other Wei-ya distributors are Alva Amusement in Miami, Florida and Atlas Amusement (a.k.a. 8liners.com) also in Miami. Then there's also Billabs who rebrand Wei-ya chassis as their own Billabs brand.

Thanks Ken, but that site doesn't help at all. I think I've worked it out from this picture:


A quick question though: On the Wei Ya monitor chassis there are two rows of pins for the horizontal and vertical connections labelled A and B. Anybody know what the difference is?

Thanks all,

Charlie

one is a reverse picture

[char1ie]

Do you mean that the A pins are the reverse of the B pins? So the same connections will give a reverse picture depending on if they are on the A or B pins?

Thanks,

Charlie

Yeah, pretty much.

Just be sure that you have the horizontal pair and the vertical pair are on the correct pair of pins otherwise you WILL fry something quickly. (there should be a spacing difference between the pair of pins)

If you have a one piece four pin connector coming from your yoke..... then it should only fit on one way regardless of which set (A or B) of pins you choose.
If the picture is upside down or backwards, move it to the other set of pins.

The plugs are different widths, as you say. And there is an H and a V by the pairs of pins so I should be OK with that.

Black wire running from the metal strap is an eath and goes to a pin on the yoke board.

Big red double plug is the degauss and goes to a pair of pins on the chassis.

And that's that. Tonight I should be able to put my jamma loom, 60 in 1 and new monitor into the original Pacman cocktail. I'm sorry to say that I intend to drill buttons into the original control panel overlays.

er no it goes to the neck card earth pin

Hi Char1ie,

How did you get on? I've also just got hold of a 20" Wei-Ya monitor and chassis (C2620HR) and haven't got the faintest idea how to connect the two up!

I don't suppose you could post a pic or two to help me could you?

Thanks

Well, I got a reply from Wei-Ya (seems like I'm the first one, but I asked nicely  ) with a circuit diagram for the C2620HR.

It doesn't help me (because I'm no electronic engineer and need point by point guidance), but at least it may help someone else.

Hi,

I just bought a brand new Wei-ya monitor and chassis - Model 2620HR (20H), 20" Chassis, 15.75khz, Input 90-260V.  Here is the spec sheet from the Wei-ya website:




I have a few questions...

1. First off the monitor that came with it is Model A51AEZ90X17, which according to the Wei-ya website is 21", rather than 20" (the 20" begin with A48...).
Q: Is there any issue with using the chassis with this monitor? (I purchased the monitor and chassis as an item from an arcade parts seller in the UK).



2. The chassis has an Americal 110V plug. However as I am living in Ireland, and we use 220V domestic sockets. 
Q: The Wei-ya spec sheets says 'Input 90-260V', does this mean that I can snip off the American plug and swap it for an Irish/UK (220V) plug without any further modification?



3. My arcade cabinet has a transformer. If the label on the transformer is correct, it appears to be stepping down from 220V to 110V.  This might make sense as domestic supply is at 220V, and the old Hanterex may have only been capable of accepting 110V.  (in the photo - the green connector is a 4 pin, used with the old Hanterex monitor).
Q: Do I still need to wire the new monitor/chassis to the transformer?



4.  The chassis has two rows of H/V pins.  From the forums, it sounds like I should keep to one row only (I have seperate H and V connectors).
Q: Which row is the correct one for Wei-ya Chunghwa monitors - Row A or B in the photo?



5. Finally, the Hanterex chassis uses a 6-pin video connector. The new chassis uses a Jamma 5-pin video connector (R,G,B,GND,SYNC).  I have searched everywhere on the web for the 5-pin video connector, and can not find them sold seperatly. Unfortunately this means I may have to buy a full Jamma harness (expensive) just for the sake of this video connector.
Q: Does anyone know where I can purchase one seperately. Unfortuntely, living in Ireland means that many websites won't deliver outside the US


Any help is greatly appreciated, as I would really, really like to start playing some games again   
Thanks, Alan.
