Monitor Screen loses Some Color and Color Appears to Shift

Hi, I've got a Sony CRT 21" monitor and Dell SX270 w/ digital out for video
to a digital/analog converter to the analog cable on the Sony monitor. .
Lately, the video has been displaying images that have a reddish tint and
the colors are somewhat smeared. I've run across this problem before on
other PCs and was able to fix the problem by disconnecting the video cable
than reconnecting them. Occasionally, the PC will start up displaying the
correct colors then revert to the smeared colors. Any idea what's causing
the problem and what I can do to fix it?

How old is the Trintron? They are known to die in such colorful ways. I've
seen several of the 17" models display a reddish tint within Windows on
their way to failure.

My 19" Trinitron (IBM) began to "fade" around the edges at desktop along
with eventually displaying diagonal "pinstripes" visible both at the Windows
XP splash screen and also less so (but still lightly visible) at desktop.

If the monitor is older than 3 years old, it might be signalling its
ultimate exit.

Have you swapped with a different monitor by any chance?

You could try installing the latest vid drivers from Dell.
When the colors are smearing, try giving the monitor a sharp rap. If it
changes the picture, it is probably your monitor.
You could also try the de-gaussing button on the monitor.
I am just guessing with the above suggestions.

I have an 11 year old Sony Multiscan 100sx. Over the years it
had a few minor problems which lasted a few weeks and "went
away". Sony magic.

It is now having a more serious problem which I will have to
have fixed although it also, strangely, appears to be decreasing
in frequency and "intensity". It is similar to yours, and it is
intermittent.

I was told by a technician there is a small PCB right behind the
Trinitron tube which controls the three RGB colors and that the
capacitors on it sometimes start going bad. You can tell by
bulging of the top of the tube-shaped capacitors or by outright
obvious signs of problems (leaking goo etc.). Poor solder points
may also be deteriorating - very easily fixed.

When the image is OK, is it as good as it was 11 years ago. I
hate LCD's.

While I am not afraid of fixing a lamp, I do not feel like
opening up a TV/monitor. But I am reasonably sure I can have
this problem fixed.

You can also Google for "CRT monitor color shift repair problem"
or some such combination. There are lots of repair advice sites.

If you can find a Trini built in the last few years before those
idiots stopped making them, GET ONE. Take advantage of all the
morons switching to the LCD ****. I saw a widescreen (!) Trini
for about $300 a year or so ago (it was about $2,500 when it
came out). A high-end Trinitron /should/ last forever (mine is a
very basic model and it has lasted 11 years of 5-10 hrs. of
daily use).

Mine started out intermittently and has become chronic.

bulging of the top of the tube-shaped capacitors or by outright

I'll buy a nice new LCD.

TEN years old? That monitor owes you nothing! You got good mileage out of a
quality brand-name product. Stick with another good brand name, not like most
of the junque sold in Best Buy and Circuit City... Ben Myers

Agreed. My 19" began to fizzle after about 6 years of nearly continual use.

I'm not complaining just need to get more mileage until I get a new one.
Also, I've seen the same problems on LCD monitors that was fixed by
reseating the cable connections or replacing the monitor cables.
