Hi,
I've got a Mitsubishi DiamondPlus 74SB CRT monitor here, and it looks like
the anti-glare coating is coming away from the CRT glass. There are a number
of "pockmarks" in the coating, and along the top and bottom edges, a 5mm area
of the coating has disappeared, mainly around the plastic bezel. The monitor
is three years and three months old, manufactured 44th week of 2002, on my
desk on the 3rd of March 2003.
The only thing the CRT has ever been cleaned with is a microfibre cloth and
filtered water ("filtered" as in "gone through a ceramic/activated carbon
'pure water' filter"). On one occasion shortly after I got the monitor, I used
a CRT cleaning cloth (basically distilled water and a neutral detergent on a
microfibre pad) but that's it.
I had a Samsung Syncmaster 3 before the Mitsubishi, treated them the same
way and never had any issues with the coating - the Samsung is now nearly
eleven years old, the contrast pot is pretty much worn out, but the CRT is
still as bright as ever...
I'm at a loss to explain this, and the only answer I managed to get out of
NEC-Mitsubishi (well, NEC Display Systems) was - in effect - "it's your fault,
you can only cause that if you use chemicals to clean it."
I've also noticed that the CRT seems to have started picking up a very
nasty level of static charge - to the point where if my hand goes within a
quarter inch or so of the CRT (as it does when I switch it off), I get a
static-shock that's severe enough to cause my entire arm to spring backwards.
Is this likely to be related to the failure of the coating?
Can anyone shed some light on this annoying little issue?
Thanks.
