Convergence-problems with WG U3100 & Happ
Carsten Carlos:
Hello overthere!
I got a big convergence-problem with a WellsGardner U3100 19" (M2TS26H-chassis) I bought 1.5 months ago from Happ. Basically at the bottom I got a very annyoing red shadow / the red line is about 2mm above the rest of the horizontal lines there. In the middle of the screen convergence is quite good enough, though not perfect, at the top it's noticable, but still something you can live with.
I'm mailing with them for 24 days now.
Now they finally found out that it's not an easy adjustable thing (yesterday they told me I could try the rings around the tube but this is not a job to take on lightly) and that they can't do anything about it - guess what they mailed me?

monitor manufacturer.
Convergence specs on the 19" TV type CRT are < 3 mm
at edges and < 4 mm at corners. These pictures show the misconvergence to
be less than 3 mm at bottom edge which is in spec.
The consensus then is that this monitor is within specification. Please
bear in mind these 19" Game Monitors are not the same specification as the
computer monitor on your desk both in the chassis or the tube specification
and are obviously larger and more curved which exaggerates the problem.
It may be possible to improve the current setting a little by adjusting the
convergence rings but this is not a job to take on lightly as you can make
the situation worse.
>From the front of the tube there are two purity rings first and these are
even harder to set, so I really don't suggest you move these. If they have
been knocked, look for the glue or paint line which is usually used to lock
them in place. If it appears miss-aligned then carefully re-align them but
remember first where you found them in case you have to set them back.
Behind the 2 purity rings are three pairs of convergence rings. adjusting
these together and individually will alter the convergence of each colour
but, as I said moving these should not be considered lightly. With care
however, and by marking exactly, and carefully, how they were when you
started, you can try adjusting them and simply put them back to the original
setting if it doesn't help.

Hey, I can't believe that a convergence-issue around 2mm is in there specifications! Wells Gardner is the biggest and most used in game-monitors, or did I got something wrong?
Anyone here that got such a bad convergence, or got a knowledge what their specifications really are?
To add, I ordered this from Happ UK 'cause I live in germany. They billed me about $780 for this monitor - I somehow get the feel that they just want to take it back and refund me 'cause its that much money! ::) In one of the earlier mails from them they stated me that this could also happen with a new one, so in my opinion they should fix it or refund me. ???

I got some pictures online of the screen showing a white grid:

I also have a total of the whole screen, but the digicam just doesn't catch the effect anymore when I photograph it like this. Of course, looking at the monitor in normal gaming distance shows the effect very strong, even during gameplay!
SNAAAKE:
carlos,
i am having similer problem :'(..not as bad as yours but similer..try and get in touch with MAMEFAN..he knows what you can do to solve..but if you ask,i would say..try putting back the black coil wraping around the monitor in place..it happens when you use drill and other electronic device around the monitor,that wraping automaticlly moves or something by itself.i am still not sure what happend to my monitor,only has like a round spot where i am missing some color.

Carlos - That sucks. Does the monitor happen to still be under warranty? If so, find a reason to return it and ensure that they won't just send you the same one back, if you know what I mean. After having paid that much for the monitor in the first place, having to live with that problem would be unacceptable.
sNAkke - Most likely the black coil you are trying to describe is the degaussing coil. Degaussing the monitor won't correct the convergence problem shown in Carlos' photos.
Carsten Carlos:
Xwing, I bought the monitor from them just 6 weeks ago - plenty warranty on it!
Problem is that they now want to cheat me telling me that this is in the specifications!
I mailed one of the technicians at Wells about this, maybe I'm lucky and he mails me that they are wrong.
