1084 Reference
-----------------------------------------------------------------------------
The 1084 and its variants (1084S, 1084S-P, 1084-P, 1084S-P2, 1084-D,
1084S-D, and 2080) are all 15.75 kHz monitors. They do not handle AGA
"double" screenmodes, nor will they display the deinterlaced output from
the A2320 Amber board or the motherboard deinterlaced output on an A3000.
However, they will show all normal 15.75 kHz displays, and many (most?
all?) of the 1084 versions have a separate input for composite video.
The 1084 is a usually a variation of the Philips CM8833 monitor; the
1084S-D was made by Daewoo (as was the 1084D, probably). The display tubes
used in these monitors were made by Orion, Toshiba, Hitachi, and Samsung.
At one time or another, every possible permutation of connectors and video
capabilities on the 1084 seems to have been reached, so don't be surprised
if your 1084 has some bizarre combination of connectors and specifications.
Common Problems
* The door covering the front-panel controls is typically broken off.
* The attached cables or connectors on some models tended to fail,
causing loss of color or other problems. Resolder the pins. You can
glue connectors in place to provide support.
* Failed or insufficient insulation may cause arcing.
* The power switch may partially fail, causing separate parts of the
monitor to power down.
* A phone caller suggested that internal connectors could tarnish with
age, and disconnecting and cleaning them may help clear up some
problems.
* Repeatedly blown fuses can indicate a bad power supply.
* A loud whistling noise indicates a bad flyback transformer (also
known as an LOPT).
Some 1084 monitors also have digital RGB (PC clone CGA) inputs, and there
was such a profusion of minor or major variations that any 1084 might have
any combination of analog RGB, digital RGB, and composite inputs.
Other Notes
* The 2080 is a long-persistance phosphor, .39 mm dot pitch.
