I turned it on and found there was no sound and the screen was all green. Since then, I&#8217;ve determined the original arcade board (the PCB) was bad. However, the screen remains green, so I&#8217;ve been doing research to find out what exactly I need to fix on the CRT monitor to get it working again.<\/p>\n<p>My monitor chassis is a Wells Gardner K7000 and on the advice of several people who have worked on monitor repair before, I was told to replace the capacitors, the flyback, and the Horizontal Output Transistor, i.e. the HOT.<\/p>\n<p>Over the course of two late nights, I made the repairs. (Boy, I learned a lot. I&#8217;ll have a separate blog post on some tips for replacing the flyback and caps.) I put the monitor chassis back in the arcade machine today to see the results of my hard work.<\/p>\n<p>Here she is after getting a new flyback, caps, and HOT. I cleaned up the PCB and wires as well, so she&#8217;s looking real clean:<\/p>\n<p><a href=\"https:\/\/www.ussherpress.com\/blog\/?attachment_id=987\" rel=\"attachment wp-att-987\"><img loading=\"lazy\" class=\"aligncenter wp-image-987 size-full\" src=\"https:\/\/www.ussherpress.com\/blog\/wp-content\/uploads\/installed-e1702162396791.jpg\" alt=\"installed\" width=\"400\" height=\"299\" \/><\/a><\/p>\n<p>The good news is nothing blew up. I can also adjust the the screen enough that I can actually see some gameplay! The flyback is working much smoother. The old one had high pitched hiss. When compared against the <a href=\"http:\/\/www.youtube.com\/watch?v=wHucMlS087w\">YouTube video I took<\/a> of this <a href=\"https:\/\/www.ussherpress.com\/blog\/?p=900\">a few weeks ago<\/a>, you can see that there are no more wavy vertical lines on the right. I suspect the replaced capacitors fixed this up.<\/p>\n<p>The bad news is that it&#8217;s still green and still has horizontal lines. \ud83d\ude41 Actually it&#8217;s green with hints of blue. If I crank up the brightness or contrast, I see even more blue. This was what I was seeing before the repairs as well.<\/p>\n<p>Here are a couple of pics:<\/p>\n<p><a href=\"https:\/\/www.ussherpress.com\/blog\/?attachment_id=983\" rel=\"attachment wp-att-983\"><img loading=\"lazy\" class=\"aligncenter wp-image-983 size-full\" src=\"https:\/\/www.ussherpress.com\/blog\/wp-content\/uploads\/titlescreen-e1702162423747.jpg\" alt=\"titlescreen\" width=\"400\" height=\"299\" \/><\/a><\/p>\n<p><a href=\"https:\/\/www.ussherpress.com\/blog\/?attachment_id=982\" rel=\"attachment wp-att-982\"><img loading=\"lazy\" class=\"aligncenter wp-image-982 size-full\" src=\"https:\/\/www.ussherpress.com\/blog\/wp-content\/uploads\/fireball-e1702162445298.jpg\" alt=\"fireball\" width=\"400\" height=\"299\" \/><\/a><\/p>\n<p>In the end, I am happy with my work doing the cap kit and flyback repair. I can&#8217;t believe I actually did it. However, there&#8217;s still more work to be done, so stay tuned.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>If you&#8217;re just joining us, a few weeks ago, I got a free, yes, free, Street Fighter II: Champion Edition arcade machine.
