I recapped my first monitor a wgm3331. Its a u3000 chassis. I thought it went ok until I hooked it up and got this. Horizontal lines on the screen. Do I have something hooked up wrong? Need some help on a solution.

What happens when you turn th brightness/contrast down? Go back over all of your work and see if you see anything wrong...
 
lines go away.......brighter i go the more intense the lines are. if it makes any difference the lines are green.

Well, of course the lines are going to appear as you turn the brightness up. The point is to have a nice bright picture with the brightness turned down enough to not see them.

It's not uncommon after a rebuild to have to readjust the brightness, contrast, and color levels to optimum.

Make the lines go away, then post another pic...
 
Well, you don't want it that bright when you're playing. Turn the brightness down and see what it looks like. If it's not good, post another pic...
 
Will do. So is this something that will fade away over time? Before the recap the monitor had bad pin cushion and would loose sync frequently. Thanks for the advice mod
 
You don't understand. There is nothing to "fade away over time" because it shouldn't look like the pics you posted. Your brightness was too high. Turn it down. Now, if your picture doesn't look good, you have another issue, or have more adjustments to make.

So - turn down the brightness and see if it looks good. If not, take another pic and post it here and we'll go from there...
 
the lines are retrace lines. if you had weak caps before, and all your adjustment pots were cranked to compensate, your levels will be way off after capping.

my rule about brightness is to turn it down just enough to where black backgrounds do not show up in the CRT, black should be virtually invisible -- you should see no "black dots" in the raster.

contrast, likewise, you don't ever want that turned up super high, cause it increases the chances of burn-in (high brightness will do the same), put unnecessary stress on the tube, and will be a smeared bundle of shit anyway. get a screen that just has like red, green, yellow or white text, gradually turn your contrast up to where you start seeing bleeding off the side of the text. then keep turning it down until the bleeding disappears.

for both of these functions you have some "master" controls available as well: the Screen pot on the flyback being the main brightness setting. if you're ever unable to get a picture to be bright enough or you can't get it dark enough, you have to adjust the Screen pot accordingly to find that happy medium to get your Brightness pot where you can adjust it within acceptable spec.

after a cap kit, I don't think it's so likely much on a newer monitor like this one, but if you notice your white balance is off at all, you'll have to flip some of the necessary bias pots for the R G B on the neckboard.

I'd work on turning the Screen down first. that will create retrace lines with great ease. find a black background like a test screen or something to adjust it with.
 
Thats the best I could get it.

So - you can't turn the brightness on the flyback, or the brightness on the remote, down any farther to make those lines go away?
 
colors won't show vibrant if they're washed out by high brightness.

I fail to believe that you can't turn the brightness down any further at the flyback.

and if you can't, then it's time for a new flyback lol

turn that thing counterclockwise until it starts getting dark. you should be able to maybe even turn the knob a a third or half turn and have it where you want it to be. retrace lines mean your shit's turned way up.
 
looks like its the flyback. they only go away if its turned all the way down on the flyback. i went to take a pic and the screen went all out of sync again....wtf i guess the b+ is randomly dropping cause this?
 
Turn the flyback down until the lines go away, but the picture is still there, then turn the brightness or contrast on the remote up...
 
it comes and goes. im still thinking the b+ is causing this garbage on screen. the lines go away if its at the lowest setting. but just a slight turn to make it perfect they come back.
