WG Monitor With No "Horiz Size" Control?

[chinabox]

My arcade is slowly coming along.  Got my ArcadeVGA and JPAC working today.

However, I can't seem to *fit* my desktop or Mame games onto the screen no matter what resolution I use.  I feel like I need to change a setting on the monitor, but it doesn't have a Horizontal Size control.  This WG arcade monitor used to be upright, but I have turned it on its side for this project.  Has anyone else head of this sort of thing?  I've got all other controls: Horiz Pos, Vert Pos, Vert Size, Focus, Black, Etc...

Am I SOL when it comes to monitor configuration?  Am I missing something obvious?  I've checked the dials on the back on the monitor as well as the monitor control panel near the power supply unit in the cab.

Thanks in advance for the help!

ALL monitors have a width control (a.k.a. Horiz. size). Post the model number of the monitor and/or pictures and I can show you where it is.

Thanks!  A bunch of pictures of my cab are here:

I hope there's enough there...

I should also mention that it looks like there might be a PLACE for Horiz Size but no actual dial to play with.  Is *that* possible?

ken will need pictures of the PCB(s) at the back of the monitor (the chassis).

[Ken Layton]

Yes, pix of the monitor board are needed.

Looks like a K7000 to me (has the long remote board plus other clues are the portion of the chassis showing the pots and the location of the video signal connector).

The Horizontal width coil can be used to stretch the width out a little along the long axis (which appears to be the vertical size in your cabinet, since the monitor is mounted sideways).  For the K7000, you can also replace C38 with a different value to change the size if you find that the coil does not do enough for you.

Jason, your link was right on target with the location of the adjustment dial.  However, I managed to break the "tool" portion of the dial, which means I can't fit an Allen head in there anymore.

I think I'm screwed.  I hope not.  PLEASE, any ideas?  I hope I'm not up the creek here...

So are you saying that the ferrite core is cracked?  if so its pooched--you should be able to order one from wells gardner and replace it, so all is not lost.

[Ken Layton]

Bob Roberts sells the width coils for many makes/models. Yes, you can also buy direct from Wells-Gardner.

I'm taking it to a TV repair shop tomorrow.  I'm too afaird I'll screw something *else* up in the process of fixing it...or exploding the whole thing along with myself.  Plus, of course, I want this done as soon as possible.  I think I'll just have to replace the whole unit.  

Any price estimates for the part?  labor?  I'm hoping not to spend an arm and a leg here.

You might not have to get it repaired.  The picture will be at its widest with no slug in the coil.  So, remove all pieces of the broken slug, and see how the picture looks--it might be as wide as you need it, or just wide enough to be "acceptable" without paying someone to work on it.

In the past, I've broken pieces off of stubborn slugs before, and was able to remove them and reuse them by turning them upside-down (there's often a hex socket on both ends of the slug).  This won't work if the fracture goes clear through the slug, but if the damage is just at the top near the hex socket, then this will definitely be a possibility.  If you can't work the slug from the topside, you might be able to desolder the coil from the board, and turn the slug from the bottom.  

If it doesn't turn with minimal force (you saw how fragile the ferrite is), be sure to heat all sides of the coil with a blow dryer for several minutes.

If you need to replace it, Bob Roberts lists the K7000 Width Coil at $10 (US Dollars).

Thanks for the input Jason.  Problem is, I need the screen much more *narrow* than it is.  D'oh.  The main problem is that the main monitor board is connected at an angle and is hard to get to in my cab.  So I think it was being turned and pushed to the side as I was trying to change the coil setting.  Oh well.  I should have rotated the monitor to work on it.  Lesson learned.

I'm really too afraid to touch it anymore...I'll let some professionals take a look at it (unless it costs me two arms and a leg).  Hopefully, I can get it taken care of (parts, labor) for under $50.  That's the hope anyway.

*crossing fingers*

[JasonF]

Oh, narrower.  Hmm, ok.  Normally it's the other way around (that the game puts out too narrow of a picture).  

It might be tough for someone to work on the monitor without your video source, especially if the TV shop is not set up for arcade monitor repairs.  Even if they do have a 15kHz signal/pattern generator that works with RGB+SYNC, you still might offer to provide your cabinet so they have your signal to work with--this would allow them to swap out C38 if needed to shrink the picture appropriately.  Just a thought....  

I know that I have a lot of monitors come my way that look great on my test jig, but do not look the same in their actual cabinets due to differences in what my test jig's video puts out versus the other game's.

Crap crap crap crap.

My local TV repair guy here doesn't know where to get that component.  Of course, I can get it from Bob Roberts, but then I'll have to install the damn thing after it's shipped to my house.  There's a $45 "Bench Fee" to install something at this place too.  So now I'm out *at least* $55, plus shipping and time.

Crap.

I'm slowly considering pruchasing a 21+" CRT, and selling off my ArcadeVGA.    Of course, then I'd have to lose my JPAC and replace it with an IPAC.  Or, I could just keep it the way it is and deal with the screen being much larger than it needs to be.  I don't like that idea though--it looks bloated.

Oh dear.  Not sure what I'm going to do.  Ideas?
