It could be that one of the caps that you used to install the cap kit was bad or that you accidentally installed an incorrect cap somewhere. We would recommend going back over the cap map you got with your cap kit and double checking the voltages, polarities and microfarad of each cap to make sure that everything is correct. This problem definitely still sounds like a cap issue and can probably be fixed with just a closer look at your chassis.

A thin horizontal line is usually indicative of a problem with the vertical section of your monitor chassis. More than likely one of the solder joints somewhere in this section is cold or broken. You should probably take out your monitor chassis and check all of the solder points to make sure that everything is making a good connection. You especially want to check around the chips on the board to make sure that all of the pins are soldered correctly. Check our our post on More Troubleshooting Monitors With Michael for more information.

Sounds like the flyback on your monitor could be going out. You might look at it to see if you can find any cracks or holes in the casing. If you find some visible problems with your flyback then you’ll need to replace it. You will need to know what kind of monitor it is before you can replace it. Check out the What’s My Monitor page on Bob Roberts site to help you identify the brand and model of the monitor you have. You should also be able to buy the replacement flyback from his site as well.

Make sure that you are adjusting all of the pots brightness and not just one. There are typically three pots that control what most people consider brightness on a monitor. There should be two pots on the chassis or on a remote board that are called brightness and contrast. Make sure that you are adjusting both of these and not just one. The other pot for brightness is located on the flyback which is what the anode (or suction cup looking thing that attaches to the tube) is connected to. You will probably find two pots when you look at your flyback. The other pot is for focus so it should be pretty easy to tell which pot does what just by adjusting them a bit. Play with these three pots and see if you can get your desired picture. If you still can not get it to look the way you want it to then you should probably look into a cap kit at that point.

You definitely need to get a pot for your brightness adjustment as this can cause a lot of crazy issues. You can buy a pot from Bob Roberts (http://www.therealbobroberts.net/pots.html). While you’re replacing that pot, it would be a good idea to do a cap kit and refresh the solder around the vertical and horizontal IC chips on your chassis. The horizontal collapse that you are describing is going to be related to one of these parts. You should be able to get a cap kit for the Sanyo EZ monitor that’s in your cabinet from Bob Roberts as well. Take your time and keep us updated on your progress.

I currenty just brought home a Donkey Kong Jr. Machine. I was told that there was something wrong with it when I purchased it. When I turn it on, there is a thin white line on the monitor. I can hear nosies for game play and all..just can’t see what it is going on. The third knob in the pic seems loose. Any ideas? Thank you for your help.
