Appendix G: Installing A Cap Kit
If you do not have a manual for this monitor, get a copy, as it does a good job of explaining how
each section works and also how to adjust it.
For those who do not like reading manuals, or who do not feel like locating local sources for
specific parts or who do not want to hunt through a huge catalog to put together part numbers for
an order, you can probably order everything you need (except for the upgrade parts and the extra
capacitor for P329 versions of the HV unit) bundled together in one package from Zanen
Electronics. I suggest you order a couple of these to keep as spares since you never know when
you might need to do a rush repair job and the price simply cannot be beat.
Call Zanen at +1.806.793.6337 and ask for "get well kit #206" which at last count had thirty
pieces including all the capacitors that go bad, six replacement chassis transistors, several of the
smaller transistors (and their corresponding resistors), several diodes (including ZD902), and
somewhat sparse documentation on how to replace the parts.
Ordering a kit from Zanen also entitles you to FREE technical assistance and they seem to be
very experienced and knowledgeable. As of January 2002, the price for this kit was $15, which is
probably cheaper than any deal you could put together yourself.
A Cap Kit is a good way to go if you do not feel like doing any testing to find out what exactly is
bad. If you replace all the parts included in this kit, you may be throwing out a lot of parts that
still work OK (but which may be on their last legs, anyway), but in most cases you will have a
working monitor when you are done. If you replace all these parts and the monitor still does not
work, then go through the flowchart shown later in this document. It is quite likely that you have
a bad HV transformer and you will have a heck of a time locating a replacement.
Be aware that some of the parts that Zanen will send you are from the original specifications and
should not be used, as this spec is known to be deficient. Consult the section below about how to
upgrade the deflection board and switch out the indicated parts for the upgraded replacements.
