Document Title: [RasterMonitorRepairHelp.html (html file)]
When I first got into collecting arcade videos I found monitors to be truly daunting. I spent many hours struggling with repairs even though I had some minimal background in TV repair. I've discovered several things in the last few years to greatly aid in the repair of raster arcade monitors even if you have only minimal electronics skills and I thought I would share the information with those that are interested.
The 4 most common raster monitors used in early 80s arcade games are the Electrohome G07, Wells-Gardner K4600 series, Wells-Gardner K4900 series, and Wells-Gardner K7000 series (this one is much less common than the other 3). Randy Fromm has spent years of his life helping educate inexperienced game technicians and the September 93 RePlay magazine contained one of Randy Fromm's Technical Tips covering these monitors. There is some text but the article is mostly troubleshooting flow charts for each of these monitors.
It is an outstanding article! Even without any real understanding of how a monitor works and only really basic electronics skills you can fix a host of problems if armed with this article.
The other big thing is the Zanen Electronics (806-793-6337) "Monitor Get Well Kits" that get mentioned from time to time in this group. I've installed more of these than I care to count and they work miracles on distorted and tired monitors. Most of the kits are under $10 and are made up mostly of electrolytic capacitors replacing the tired ones that are no longer doing their job in your monitor.
I'm not about to try and type in some kind of ascii version of the Randy Fromm article but I am willing to send copies to you by snail mail along a listing of the Zanen Electronics Get Well Kits. IF YOU ARE INTERESTED SEND ME YOUR STREET ADDRESS and I'll drop a copy of this info in the mail to you. Rick Schieve (firstname.lastname@example.org)
