Odd, don't believe I have seen this before, definitely not at mild
temperatures....the top LCD-screen on my EOS-1 going faint....had it
stored in a cold/unheated room for several months, fed by a BP-E1 set
of NiCd's, containing one bad (high self-discharge) cell, so on the
charger from time to time (no batteries in the camera at those times,
and the pack often being dead (but mostly enough left to make 'BC'
blink normally).
Today, when checking the camera again (first time since temperature
dropped), the screen went very faint, and not very homogenous either,
the individual LCD-segments being active quite erratically, but
overall more faint than 'broken').
At first I thought it was the batteries, but mounting a full PB-E1 on
that camera didn't help, and mounting the near-empty PB-E1 on my
other EOS-1 camera didn't provoke the same symptoms either, just the
usual empty signal.
And after storing the 'broken' camera in a warmer room, the problem
is gone.
Could this symptom be related to the on-board Lithium (memory)
battery going down? Together with the normal batteries being
empty/removed?
(I have often wondered what the symptoms of that would be....OTOH,
with the normal batteries out/empty, this Lithium doesn't feed the
LCD-screen either....)
PS: I don't believe it has anything to do with the industry-wide
warning that LCD's won't last more than 7 years....by now, the life-
span of the earliest EOS camera's is double that (nearly triple for
the FD T60/70/80/90), and I haven't seen this complaint anywhere
thusfar....not with other camera brands either btw.
(it might be a worst-case scenario with continuous exposure to
sunlight, as LCD's are based on polarisation-foil, and polarisation
filters in general are said to loose effect over time, but only when
exposed to light AFAIK).
