2.11 Will it be impossible to find replacement electronic componentsfor CED players, when these are no longer available from the originalmanufacturer?

Actually, looking 20 years into the future, CED players will be easier
to service than, for example, a DVD player purchased new today.
This is because CED players were manufactured in the era when consumer
electronics used mostly off the shelf components, and the "through
board" mounting of components, which facilitates replacement of
individual components with little more than a soldering iron. Most of
the capacitors, inductors, resistors, diodes, and transistors used in
CED players can still be purchased at your local Radio Shack, and even
the integrated circuits were industry standard parts when possible. The
exceptions are the microcomputer IC's, and a few IC's specific to
VideoDisc signal processing. Even with these IC's, the chips can often
be scavenged from broken players set aside as parts machines. For
example, the same CMOS DAXI Buffer (an IC that transmits digital
auxiliary information recovered from the disc to the system control
microcomputer) was used in all RCA players from the SFT100 through the
SKT400.

Contrast this to modern consumer electronics, which have application
specific integrated circuits throughout and employ multiple layer boards
with surface mount technology. These innovations have resulted in
reduced cost, size, and power consumption, but have made circuit level
repair very difficult. The standard repair practice nowadays is to
replace the whole circuit board, or simply dispose of the entire unit. I
have prepared three documents to facilitate replacing defective IC's,
diodes, and transistors in RCA players-- RCA Player Integrated Circuits
by Player Model Number, the RCA Player Integrated Circuits Reference
Guide, and the RCA Player Diode and Transistor Reference Guide. Another
document, CED Player Parts Sources provides links and phone numbers for
a number of OEM and generic parts suppliers.These documents are available
at the URL listed in question (2.1).
