White lines on top of of the screen

[Pink_isn't_well]

I'm using a Philips 105S monitor, a 15'' CRT. I've been using it
daily for about 4 years. Recently it gives me a problem. After it is
turned on and used for about 10-15 minutes, white lines (not perfect
lines, more like snow or something) appear on the upper part of the
screen, they resemble screen corruption although it is possible to
see through it and work on the computer. The width of the corrupted
area is about an inch or maybe a little more.

They don't go away except if I turn the monitor off, let some time
(about 15 minutes) pass and turn it back on. I suspect it happens
when the monitors temperature reaches some point.

I tried the monitor on another computer and the same story happens.

What could it be? Has anyone seen this before?

It may be a aged-onto-failure horizontal circuit capacitor.
While the part itself may not be expensive, the time and
expected (remaining) life of the monitor in combination with
it's current value may not make it worth repairing.

You (anyone) deserves better than an old 15" CRT these days.

This statement doesn't necessarily apply to everyone !
I have a 15" Compaq monitor on a machine running Windows 98 approx. 5 years
old.

I also own a laptop with a TFT screen ,approx. 2 years old. The CRT gives a
much clearer picture and when my monitor fails I will search high and low
for another 15" CRT . I believe they are still being made by some
manufacturers.

Salvation Army. Goodwill. I can sell you one at a very reasonable
price. I used to used an 8 inch b/w on the Kaypro, and the Osborne
had something even smaller.

That's nice, and I still think you deserve a decent modern
monitor. It is the primary user interface to the system.

That doesn't mean you need a _15"_ CRT though, they're
mostly cheap junk these days. The small old tech is now
mostly reserved for low-end products made in China et al.
If you prefer a CRT so be it, but better to get a decent 17
or 19" CRT if you really care about clearer pictures.

There is no technical advantage to a 15" screen, unless you
live in a small closet and anything bigger simply won't fit.
They may not even be cheaper, I've bought 17" and 19"
monitors for a bit under $70 in the past couple years. Not
"good" monitors relatively speaking but you wouldn't get a
good new 15" for that range either.

Something weird happened. The problem hasn't presented itself again
since I last posted here. I didn't change anything, except replacing
my speakers. This had nothing to do with the monitor problem. It was
because my old speakers weren't magnetically shielded and they would
make annoying noises whenever my cellphone was being used.

The problem was reproduced several times with the old speakers turned
off though, and even away from them, with the monitor connected to
another computer in another room.

I like my 15" CRT. I love it. It's not great for watching movies of
course, but I don't like movies all that much.

The monitor is failing. Time to start shopping for a replacement.
