Trouble with monitor |
|
|
Hi Guys
Is anyone in this group knowledgeable about computer Monitors.
If so I have a question.
I have a 4 1\2 year old 19 inch Monitor (tube type) by ViewSonic for
awhile now the display has being somewhat dime. I have the brightness
at 100% and it’s still hard to make out parts of a jpg that have dark
colours in them. In your opinion is the monitor worth fixing. If it’s
a component that could be changed for around $100 I would get it fixed
or is this type of problem related to the picture tube itself.
Thanks for any advice
Nikki

For $100.00, it's a judgement call whether you want to get this one fixed,
or just pick up a new one. CRT monitors are dirt-cheap these days, now
that everybody's going flat-screen.

If it's only 4 1/2 yrs old I wouldn't expect the tube to be knackered.
Low brightness may indicate a power supply problem for example.
See if you can get a quote to establish the fault first.

If the monitor was in continuous service over that period, that' |
over 35k hours - way beyond the typical time-to-half-bright fo
a CRT. This sounds like a classic worn-out tube; upping th
internal brightness adjustment (as opposed to the external "user
control, which is typically limited in range) will help temporarily
but that tube's definitely on the way out and nothing can be don
to truly "fix" it
For what CRT monitors - or even LCDs - cost these days, th
only cost-effective answer is junk-and-replace

I have an old viewsonic here (sticker on the back says "June 1999"), I got
it gratis, it its previous life it was displaing some diagnostic 24/7 so
there's a bit of burn in and the image was dim, too dim to read easily in
a well lit room.
I took the back off and after a 30 minute warm-up turned up the screen
and adjusted the focus controls. works great now. (except for the burn in
but it's just rectangular patches near the edges and easy to ignore.)
screen and focus controls are on the side of the flyback transformer,
(black plastic thing other end of the wire attached to the rubber "sucker"
looking thing on the top of the picture tube) there's dangerous voltages in
that area so work with one hand only (and don't rest the other on an earthed
PC case for example)
I used a clamp and a piece of wood to stabalise the front of the monitor
so as not to put too much stress on the circuit board.
I also used rigid platic to support the circuit board (CD cases etc)
but mainly because my working surface was contaminaated with metal
particles.
I used an insullated screwdriver to adjust the controls - mainly to keep my
hands away from the live parts the controls are insulated.
screen is like a master brightness control one good way to set is it to turn
the brightness up to about 10% and display an image with mostly black
(full-screen text mode console in windows or linux is a easy one)
and then in a mostly darkened room turn the screen down until it stops
glowing.
focus is, well, focus. the default X-windows bagckground it a good focus
pattern (1 pixel checkerboard pattern) but any screen full of text will do
almost as well.
Bye.

| i did not read all of the replys no need if you got 100% bright how about contrast where is it? if it is dimmmmmmm then your hi voltage power supply went south for the winter. you tube is not to blame they do get burned/usage of rare earth but not in 5 years expecialy a monitor. if i was you i would trhrow it away need a replacement no $ go to goodwill ind. i bet you find a good one for $20 or less. many people change to lcd and these things get thrown away. |
