Phoenix Small Monitor

[wmacmonagle]

With out doing anything with Yoke or neckboard or whatever.. I just decide to remove Jamma Harness for ICADE and installed the 18 pins (36 connectors) and hook up phoenix. I found out the previous owner did not know what they are doing.. They installed wrong way.. I rewired and attached everything except for the CP and coin op.

Fired up and guess what i saw???

it s full screen with no problem but it is off align.. I believe the neck board are being off alight and causing this problem.. but is full SCREEN!! YAY!!!

it defiently a compabile board issue!

The tilted screen is cause by the yoke being rotated a little off. Loosen it untilo you can turn it, rotate it a little until the pic is straight, then retighten it (but not TOO tight)...

i do it while power on?

yoke clamp is where i loose it up then turn?

Well, if the yoke may resist being turned at first, so you may want to power it off, loosen the clamp, then make sure it's rotating freely. if not, give it a firm twist to break it loose.

Then power it up, turn it to where you like it, then tighten it back up...

i do not need to discharge? and rotate where rubber is? which place is best to turn?

You do understand what the yoke is? The rubber wedges should be glued into place, and should stay where they are. loosen the yoke clamp, grab the yoke with hands on both sides (stay away from the anode cup) and twist (if it's not loose enough). Once it's loose enough, one hand can easily turn it while watching the screen (or with a helper). Once it's where you want it, retighten the clamp. Try not to pull it away from the wedges while doing so...

yoke clamp is where i loose and centering ring is where i turn or whole YOKE thing to turn?

 

[modessitt]

If the rings are part of the yoke, then they will turn as you turn the yoke. if the rings are separate with their own clamp, then leave them alone. You want to grab it on the white plastic part closest to the tube, but don't worry about touching the copper wiring. it won't shock you...

If I recall right Phoenix is positive SYNC and the multi-board your trying to hook up is outputting negative SYNC. I don't know if there's a way to change the boards output but there is a way to change the sync to positive with a 74LS04 IC.

About that yoke... BE CAREFUL where you grab it while its powered up. I usually grab them right around the clamp or at the edge closest to the back of the tube. There's some substantial current running through that yoke and it will hurt if you touch something that your not supposed too.

on page 12 of this pdf you will find how to use a 7404 as a sync inverter.

Wanted to say many thanks for educating me about the Monitor basically. I had learned several things with phoenix monitors.. They are perfectly working.

Thanks again!!!!!

So what was the fix?

Twist the plastic ring (plastic spoke which picture shown) after the loosen up the yoke clamp. I was easily to turn whtever i want and put poke back upward to touch the rubber wedge.

I found the wire which had pulled and twist the yoke. I moved the wire to right place where it wont mess with yoke again.

I re tighen lightly.. DIDNT WANT TO BREAK THE GLASS NECK but twist several and yoke became lil tight that they wont turn anymore.

PERFECT!!!!

now i have to figure and learn how to solder wires to connector to the pcb. Wondered is there any like.. clamps or somethign that i couldj ust clamp em up and done? or solder is money saver and add black tape around to it ?

No, Phoenix outputs negative sync.
