https://en.wikipedia.org/wiki/Multisync_monitor

The JC-4101P3A is perhaps the first true multisync monitor. The APC-H4311 appears to be exactly the same monitor but with a model number to match the NEC APC IV PowerMate 1 desktop system unit it was paired with. The caps lists below created from the APC-H4311 (240V) version with a manufacturing date of June 1987
== Known Issues ==

===Symptom or Problem Encountered===
====Causes====
*Electrolytic capacitor failures due to normal aging.
====Solutions====
*Replace electrolytic capacitors

== Disassembly Notes ==

# Unplug power and data cables
# Turn rotating part of base through 180 degrees and slide off
# Remove fixed part of base by removing two screws
# Remove four corner screws holding rear of case to front of monitor
# Gently slide the rear of the case backwards. May need spludger to initially loosen.
# Four screws to remove rear access panel shielding
# Three screws, one on each chassis side panel and one near flyback, to remove top chassis/shielding
# Two screws, one on each chassis side panel, to remove rear chassis/shileding
# Undo screws holding joint switching regulator and interface board assembly and disconnect leads before sliding assembly upwards<br />
== Original Parts ==
