Monitor compatability problems... One year later?

[Jordan Edwards]

Yesterday after turning my monitor on, I noticed a warning
in the lower right of the screen saying something about
the USB hub in my monitor (Sony HMD A400) having had a
power surge, even though it was behind a protector.
Well, about 20 seconds later the monitor flickered in
power. Every 30 seconds it would flicker untill I
unplugged the USB keyboard from it and the USB cord
required for the hub to work. It still flickered, but far
less in-between... Now, it hasnt flickered in 12 hours to
my knowledge. New problem... The center of the screen has
gone blury verticaly. Not only that but now, when I load
IE, Windows Explorer and a couple other programs the
screen just shuts off and the power light starts to blink
in a yellow color, it does this not only upon starting the
program, but leaving it running for 10 seconds after
turning the monitor back on. The monitor doesnt
automaticlhy restart like in the afformentioned flickers.
Why I am posting here is, could this be a compatability
issue, and why, after a year of use does it do it now,
after no settings drivers or anything has been changed?
New virus I havent heard of yet? Cant imagine one
designed to do just this, assuming its even possible...
but yea...
Thanks

I don't think that it is a compatibility issue.. I would suggest that you
have either overloaded the USB hub in your monitor, or the 150 watt power
supply to the USB hub has failed..

This would cause the screen to flicker though? and
monitor to blur verticaly? and I cant imagine it making
specific programs, such as IE, shut the monitor off, while
other, more recourse intensive things such as Everquest
dont effect the monitor at all...

I once had a problem with the initialization screen after loading IBM's AIX
onto an RS6000 machine.. the AIX symbol was corrupted, lines appearing thru
it, and colors not as they should have been.. I considered that it must be a
software problem, so loaded the image again.. I used two different sets of
AIX cd's and two different tape images, but still no joy.. I took the
machine apart to reduce it to basic configuration, and eventually discovered
that the NIC card was faulty, even though AIX reported it as being ok.. in
this case, the hardware was not telling me that there was a fault, so I
assumed software was the problem.. replacing the NIC saw the problem
disappear..

In your case, the monitor is telling you that it has experienced a hardware
problem.. why do you think that XP is to blame?

USB devices initialize by submitting a request for power to USB hub.
USB hub then increases electric power to that USB device, limited by
hardware to that number. If a USB device attempts to draw too much
power, the USB hub will report that excessive power draw as a surge
and will limit power consumed.

Surge protector has absolutely nothing to do with this USB hub. For
that matter, a surge protector is for an event that typically occurs
once every eight years. A rare event on AC mains where 120 VAC
exceeds the let-through voltage - as must be printed on the box. This
rare event is typically 330+ volts; obviously not part of USB
operation. That further assumes the protector is located where it can
even observe a 330+ voltage difference. All of which is irrelevant to
how the USB port operates and that error message.

Is it telling me that?
Ive sence lost my manual in the near 2 years of owning
this monitor and this is the first time ive seen the
yellow blinking light... Now I would assume this was a
hardware problem, but as I didnt have the manual to find
out exactly what that signal means, also considering the
blinking isnt in a pattern (ie: sometimes it will blink 4
times, others it will blink 8)...
But why I think its a software problem? First and
foremost, when I open up IE it crashes the monitor, but it
doesnt do this on many other programs... and none that
arent related to windows...
