Title: 8liners chassis question.
Post by: M.Lanza on June 06, 2009, 07:37:29 am
I just recieved the chassis I ordered from 8liners website. It's a wei-ya 1220h.
I'm preparing to connect it to the tube I have, but the chassis didn't include any documentation.

There are 2 sets of connector pins on the board to plug the yoke wires into.
Which set of pins should I plug the connector into?

There is also a single pin next to the connector where the red wire is plugged into the board.
Do I connect the tubes ground strap to that pin?



Also, do I have to make any adjustments to the B+ pot, or is it properly adjusted from the factory?

I dont know about the ground strap question, but I had a monitor that had 2 sets of inputs like that. One way made the picture normal, the other way flipped the picture upside down.

The red jumper wire is to select one of the two pins that set the width range: (N) narrower or (W) wider. You'll see the N and W markings on the board next to each post. Set the jumper wire to one or the other that gives the best width adjustment range on your picture. DO NOT connect a ground wire to these pins as you'll destroy the chassis immediately upon power up.

There are two sets of yoke connector pins on the chassis. One set gives a normal picture and the other gives a mirror image to use the monitor in cabinets that bounce the picture off of a mirror like Terminator 2. Only unplug/plug this connector when the power is off or damage will occur.

Typically the ground strap goes up to the neckboard.
I say typically because I'm not familiar with that particular chassis.

Also, do I have to make any adjustments to the B+ pot, or is it properly adjusted from the factory?

Leave it alone.

Thanks. I think I got it now.
I didn't see the pin on the neck board.
