shaky monitor

[CasioTech]

my 17" monitor, which is about 1yr old, no warrenty, starts to act up a little before yesterday, but is full out shaking now, it viabrates like a script I made on my website


casiotech.voodoolinks.net

and I don't know if it will fail on me in the near future or not

I run it on 75hz and I have a v3 3k card. Any help will be appreciated.

Have you tried degaussing it?

[CasioTech]

yes, I have, no avail, also, I heard that maybe adjusting the refresh rate to 60 would work better, but I can't take the flickering for more than 20 min.

How close are your speakers to your monitor? Have you run this resolution/refresh rate before successfully? Have you tried any other resolutions refresh rates?

[CasioTech]

the speakers are far, and they haven't ever posed a problem, as for refresh rates, I change it, then the problem might go away, because I would change it back, and it stops, so there is no way to know if it stops because of refresh rate, or coincidence, since it's not so consistent

it's a compaq cv715 monitor

Thanks again ViperGTS

 

[Viper GTS]

Not a clue, then. Sounds like you've got a monitor with problems.

Like you didn't already know that.



Good luck.

[CasioTech]

thanks, but does this mean that it's going to die? Is it possible for it to still pull through atleast a year more.

Have you heard of incidents where it could still last for some time, even with problems like mine?

Try to move it away from any speakers or other monitors. Some monitors are so sensitive to flyback pulses (which are pretty strong signals) that they'll shake even when 6' away.

Once in a while a monitor is sensitive to just a particular refresh rate because it's synchronizing to a slightly different rate, so try something other than 75 Hz.

The third thing that can cause shaking is the degaussing circuit not turning off completely. This circuit feeds 60 Hz hum to a coil around the picture tube, and the only way to be sure that no current if slowing is to disconnect the coil, but that means opening up the monitor and possibly exposing yourself to hazardous voltages. In other words, if you don't know what you're doing, don't do this.

Thanks, Jamarno.

Any other tips are welcomed

ok, so far I have it on 1074x768@75hz sustained, no wobbling, does that mean that it will dish out another two years? Also, did I damage it by running it on the previous refresh rate where it wobbled? I mean I heard that using to high refresh damages monitor's forever, but I ran a 17" at 800x600@85hz, so that shouldn't be damage, but for a falty monitor it is. In other words, if I keep it on the lower refresh rate, will it matter if it used wobbled at the higher refresh rate, or did the wobbling do perminent damage to the tube or something?

Again, thanks for letting me ramble!

Reply's are welcome

My bet is that you have a power pack sitting close to your monitor (see this happen quite a lot with beginners setting up their new computers).

Move it away and all will be well.

Or a fluorescent light nearby (usually has to be within a foot to cause a problem).

GREG! I can't believe how crappy somepeople got on this forum, to think, greg, I helped you out before, and you call me a newbee, just because I am a junior member or just because I use a compaq monitor, doesn't mean that I am a new bee?!!?


Orange man, thanks for the suggestion,

but no, there is nothing else near my monitor, it's a year old almost

any more tips are appreciated

 

[CasioTech]

Update, it was good today, until I turned it off and on again in 5 min. then the picture started to expand and contract, so I did something which stopped it from wobbling... I just started to expand it and contrast it myself with the menu buttons on the monitor, then it stopped, so I think that it's not the tube, but the thing that adjusts the sizes of the screen..


Does anyone out there (1 out of 33,365 as of 10/5/00) know what the problem is? Or what controlls the pincussion and such that I could try to maintain.

Thanks all

This is one of the last times I am going to bump it up. Please reply :|

Sounds like some of the controls are going bad in the monitor. Try different refresh rates and see if that improves the situation.
Normal speakers next to a monitor do not cause image vibration and flourescent lights do not cause interference but yet rather the transformer which regulates voltage to the light bulb. I have an Eclipse light mounted to the top of my monitor which is a flourescent bulb with the transformer mounted at the plug under the desk and I have no problems.
You might also try different video drivers or see if you can find some monitor drivers specific for that monitor off the Compaq site.

if you're hooked up to a voodoo card that uses a bypass cable in the back (e.g. voodoo2), try hooking it up directly to the main video card. Extensions also cause that. Had a friend who's monitor would flicker when the a/c was turned on so check your power supply. If not, then it's probably the monitor. Just to be sure, check it on another PC.

If you're sure there aren't any electrical devices near your computer (which you seem to be) I would try to lower the refresh rate. High refresh rates suckup more power and stress the monitor. I don't know who makes compaq monitors but my guess is it's a cheaper brand.

My sampo (generic) monitor worked fine at 1200x800@85Hz for 1.5 years and then just died...had it repaired under warrenty it and worked fine for 8 months then a thick black line appeared verticly down the center of the screen. I was told by tech support that the flyback was probably burnt out and it would cost $65 for parts and $135 for labor (flat fee) plus I pay shipping both ways ($60). Just 2 months past my 2 year warrenty.

moral of the story: fix it before the warrenty runs out....just noticed you have no warrenty....new moral of the story: lower the refresh rate and hope your problems don't reoccur.

 

[CasioTech]

lol, I needed a good moral, and laugh!

WHat's a flyback?

 

[wesman2]

I'm not sure, but I think it's like a power transformer. The odd thing is if I don't have a lot of white on the screen the black line goes away, but the more white on the screen the thicker the line gets. I think it's having trouble generating the power for the picture.

casiotech:

I'm sorry if you thought I was calling you a newbie, I wasn't. I was merely pointing out that lots of people make this error (amazingly some of my friends who are far more electronically minded than myself have made this mistake).

anyway if it is not due to outside interference, then it's almost guaranteed to be a voltage regulator controlling either the vertical or horizontal synchronisation dying on you. They commonly overheat due to almost non existant heatsinks and use of elcheapo regulators in the first place.

The screen changing border sizes constantly (especially if a bright background is being displayed) is another sure sign of an overworked regulator.

i had a skanky monitor too, i couldn't fix it....just had to get rid of it

 

[blurredvisionx]

brassmonkey, i went out with your skanky mom one time, but she was already broken, so i had to rid of her

 

[brassmonkey7]

WTF????
