I am still using a Sony Trinitron Multisacn E400 Monitor with a ten year old
system. When I first boot the computer in the morning, the monitor manages
to support normal boot operations (I use 1280 by 1024 as a standard pixel
setting). But if another full screen window is used, the monitor will
cut out in
a manner I don't know how to describe - other than it stops all display.
It sounds as though you are changing the can rates, and that the monitor
is not locking to the new rate correctly (althogh it should). It is then
shutting down as a safety feature.
Most likely it's a capacitor problem in the horizotnal defleciton
circuit. Just don't ask me to tell you how to troubleshoot it without a
service manual.
The simple solution is to power off, then on and I have been doing this for
the past two months. I realize that with a ten year old (or perhaps older)
monitor, it will eventually have to be replaced or repaired. The latter
option
is almost certainly NOT cost effective since I have neither the tools
nor the
knowledge to do the repair myself.
I do have two questions:
(a) Is there any possibility of either damage to the other components
or even
myself if I continue to use the monitor until it completely fails?
What do yu mean by 'component' (the word has differnet meanings to
differnet people).
If you mean individual electornci ocmponens inside the monitor, then yes,
there is a slight psosiblilty of damaging things like the horizotnal
output transistor. It's unlikely becuase the monitor is shutting down,
but it cna't be a good thing.
If ou mean 'comoponents' like the PC video card, then I can't see how it
could cause any damage to those.
And I think the risk of damage to you is minimal.
(b) Is there any point in waiting 15 minutes
(approximately) that the
monitor
seems to need to warm up completely to prevent the problem in the
first
place, i.e. will preventing the problem from happening by
providing enough
time for the monitor to completely warm up prolong the limited
expected
life of the monitor at this point?
I don;t think that will do any harm, and it might do some good. If you
were an electronics type, I'd suggest using freezer spray and a hair
drier (!) on the components in the horixotnal deflection section of the
monitor to see if you cna fidn the thermally-sensitive one. But there are
high votlages areound that area, so if you do go inside, take care.
