I gots me a skinny vertical line right up and down the middle of my blasteroids 19" monior. Is this usually a cap issue or could it be something else? Thanks.
 
yes.

also could be a bad trace, cold solder joints, IC failure, diode failure, resister failure, broke yok winding ECT.............

with out a pic of the chassis what model it is Ect..... it could be something else.

Damn, that sucks...Might just buy me a new monitor. Shame though the pic on this one was bad ass until collapse issue.
 
it can be fixed if you would.

post pic of the chassis so we can see what model it is.

if it is a model that is in my sig i can repair it very easily.

I read that horizontal collapse can be caused by bad propylene caps, bad transistors, bad horizontal width coil, and a bad HOT. What the hell is a HOT? Can any of these problems be fixed without sodering? Also, I have complete horizontal collapse that happened all of a sudden...not a slow transition from full pic to slightly smaller pic...all I have is a thin vertical line.

I will eventually get around to posting a pic or 2...
 
HOT is Horizontal Output Transistor. But if it failed you would have no picture at all.

More than likely a simple bad solder joint at the yoke connector, actually. Most of the horizontal section has to be working to get a picture, since it also drives the high voltage.

Have you tried hitting it? Seriously. If it's a cold solder joint, you should be able to get it to flicker back a bit. But, it's just as easy to pull the chassis and inspect the solder joints at the yoke connector and width coil.

What kind of monitor is this?

And none of these problems can be fixed without soldering. If you don't have a soldering iron, you can buy a cheap Radio Shack iron for ten bucks - it's fine for monitor repair. When you buy solder, be sure to get 60/40 or 63/37 or similar lead/tin solder. Never use lead free solder in a monitor.

if the monitor is mounted sideways, then you have no verticle deflection, which makes more sense. Usually, a verticle IC is used for deflection and are known to go bad. They aren't difficult to replace and are inexpensive for the most part as well. If you list your chassis, you wil get more info.
 
Without pics of the problem and knowing what the monitor make and model is, this is all just speculation.

Good luck on "just buying a new monitor". New monitors are few and far in between, not to mention pretty costly.

Monitor is mounted horizontally and all I get is a vertical line...horizontal collapse, right? In which case the vertical IC should not be the issue, I think.
 
What's wrong with them? Are they prone to failure?

Notice that there are no specs on that monitor? Email them and ask for them. Looking at their current stock number, it most likely has a Pentranic chassis. If not it will have a Wei-Ya chassis. Both are Junk if you get a good one. They both put out crappy pictures at best and are notorious for various issues right out of the box. It doesn't matter to someone putting one into an 8-Liner as in most cases it sits on the edge of a bar and plays draw poker.
 
So I turned on the Blasteroids, took a look inside and smelled something burning...looked at monitor chassis and horizontal width coil was burnt up! PCB is all black around it too. Guess I found the cause of my problem...
