[Icom] ICOM ic756 screensaver?

[Adam Farson]

Hi Tom,

The LCD screen used in the original IC-756 was subject to a failure mode in
which dark blue horizontal lines appeared on the screen over time. This is
not an issue in the TFT displays used on the IC-756Pro and Pro II.

On CCFL lamps: There is an excellent webpage on this topic.

On/off-cycling does not shorten lamp life; here is an excerpt from this
page.

Can the lamp be powered on/off quickly so as to blink?
Yes.  Rapid blinking will not reduce lamp life.  Also the lamp has a
extremely fast warm up, so you can link them rapidly and still get full
intensity on each pulse. Blinking dramatically reduces the life of a regular
hot fluorescent lamp, but not a CCFL!  This is because a CCFL has no heating
filament which is the chief cause of premature failure in hot fluorescent
lamps.

Thus, you can power the radio down when not using it, without any fears for
the display or backlight.

Cheers for now, 73,
