When I turn the monitor on, it comes on and shows the picture but then turns off and comes back on and shows the picture and turns off again repeatedly. I have taken the monitor cable off the computer and reinserted it and it has come back to normal. This has happened on the original computer and also on another computer. How do I stop it from continually flashing? Thanks
There are lots of reasons why it can shutdown, but happerlly none should be serious. It may be that the B+ or Power supply is too high, look for a pot near the power supply and try turning it down a bit. Also the x-ray protection may be too high, look for the X-Ray pot, found near the FBT, turn that down too. I assume your a tech and know how and where to be carefull.
It sounds like your video
card settings are too high and your monitor cannot handle the settings. One way to confirm this is to boot into SAFE MODE and see if it still happpens. If it does not, then its the video card settings. If it does, then it indicates that the monitor is in need of service or replacement.Turn down the resolution and color depth settings all the way, and then increase them incrementally until it is as high as it can go until this problem starts happening again. To adjust video settings, right click anywhere on the desktop and select Properties. Then go to the settings page.If the display does not stay active long enough to make these changes, then boot into SAFE MODE and delete the video adapter from the device manager. Upon rebooting the computer, the video adapter will re-install itself with low default settings.Is the correct monitor selected in your display settings?Make sure that the correct monitor appears in Display properties.

My monitor probleum it will want to switch it fail all time it repartedly if it want to switch but it fail
My client have the same issue. The screens (duplicate) will randomly go blank and come back a second later.
1. I have replaced the screens with brand new Dell 23" LED (S2330MX) ones (hardware replacement cycle). The old 4:3 Dell LCD 20" screens did the same.
2. These screens are capable of running full HD resolution, but it has been lowered to the client's comfort level.
Could it be the PC or the graphics card. That hasn't changed.
Any random behaviour with a monitor, such as turning it's self off and on, or showing messages like "menu controls locked" and then a few seconds later, "menu controls unlocked" are probably just dirty control buttons getting stuck partially down on the micro switches behind.
If you're out of warranty and are moderately handy. Turn off the PC, the Monitor and all power. Disconnect the video and AC power cables. Unscrew or click off any cover over the base screws at the back, then unscrew the base from the back of the monitor body. Undo any screws going through from the back that hold the screen surround.
CAREFULLY and patiently go around the join between the body and the front screen surround and gently lever the surround off with one or two thin blades. I used two putty knives because they are firm and not sharp. Ordinary kitchen knives are also wide enough not to damage the plastic as screwdrivers might.
You are likely to find the plastic control buttons along the edge of the surround, not moving freely, with a mixture of dust, dried contaminants from your fingers and splashes from drinks over time. Give it a good wash in fairly warm water with a little dish washing detergent until the buttons move freely, then rinse, dry and refit.
If the problem is deeper, then it's quite possible that it will cost more to have it professionally repaired than buying a new monitor.
Good luck,
Steve
Lol, this is kinda a grader solution... any deep answer? It's not the video card when you put the same blinking/flashing display monitor in other CPU case and still blinking...
U R so stupid! The problems R in capacitators in internal power suply of the monitor. Go to service!

Power supply source
Check the connections between the monitor and the computer. As well as the connection for the power. Sometimes there can be a bad/poor power connection and it causes the power to go out at the slightest movement.
The lcd has three parts the screen plate(windows)/the logic(vga)/the inverter(power plug). You have 2 out of 3 working ok. The power save option via the vga(on/off, connected/dis) is rerunning the lcd self test and finding an error(the plate in this case). Parts that go are the backlight ccfl's, behind the plate, and parts of the inverter, ie capacitors, all three take a bit of power from the inverter. The self test check that all the lights are ok and the inverter is ok, else it switchs off, ie if 3/4 light work it will switch off(my own case), hence the on chech error then off, However sometime there are stages of on/off ie on/ but no perm screen display(only temp), if that is the case the following may be of help...if you put bright light at an angle close to lcd can you see a windows shadow, text icons etc, ie still logic power passing(vga),then .... (from a.n. other) after two weeks searching I finally find doctor living stone http://www.aplusperfect.com/articles/lcd_capacitor_repair more fun with paulbtorrent the takening the case bit off is like opening your wallet a second time after buying a new LCD, but you must! smallest two screw driver's flat headed, practice using two pennies stuck together()with your fingers after, one little () move and inch and {} again, with the case , it does not break, just need to lever open [once open you realize they somehow put that old briefcase clip inside!] also note the bright light test to do first to see if can see a windows
screen , and that capacitors are one for a number of things that a make a inverter work! there a transistors as well, given that however, to replace all the capacitors on my inverter, was 11 capacitors, cost me $11 (uk ebay) and already had the iron and solder. So only cost me me $11 to try and see but no luck , still fun and I still can see the screen for 2 sec' at a time plus I have a spare set of caps now in the event that the new one do go burst! you have to laugh really, what next , a new on/off button, as you work though the whole thing !
mmmMMMMmmmMMMMmmmMMMMTim Berners-leeMMMMMmmmmMMMMMmmmmcome back all is not
wellMMMMMMMMMMnnnnnnweek later land sight mmmmmMMMMMMMMMmmmmgggggggg(from
another a.n other)Generally, if the screen went out quickly, it was the inverter. If it went out over a slow period of time (flickering etc..) I would bet it is the lamp.replaceing the lamp should be pretty challenging. as that requires complete breakdown of your LCD, extraction of your dead lamp, and soldering in your new lamp... but I would like to say that I it did this after realizing it's 2 x kitchen strips inside [========] x 2 with wires that can connect back to the inverter with out any desoldering(ie kit assembly/dis) with the outter case remove (glass plate safe away) I could reconnect and see that 3/4 were working (i!i hardcard ) cause the inverter to switch off after a secound ! order ccfl and replace and going to cheap and see if I can get away with fitting a 15" in my 19' as it a 1/3 of the price ! the market as drop out there, hope the inverter does not miss the length, or the screen out put. http://www.lcdparts.net/howto/troubleshooting/LaptopCCFL1.aspx OR MONITOR, I when a head because I could get the inverter to keep the 4 going out of their shell, but in the strip, using a spare, but then I broke a wire joint and then broke a tube. But at least I found out a bit more about inverters and ccfl's ! After hong konging a part a 20.1 for $8, plus a 15, got it to work, the bottom of the screen looks like a cinema, dark at the sides, will have to order another 20" cclf at some point, but at least my HF207 is now working ok hence this note !paulbtorrent!

having the same exact problem...it started with the green led power light flickering and it would take a long time to come up and then it got progressively worse...now the led light flickers red, yellow, green and the screen displays white lines randomly as the led light flickers...seriously doubt that the monitor is repairable....paid $500+ bucks for this sucker and have only had it for 1.5 years...have 3 CRT monitors that only cost $100 bucks from the mid 90's that are all still running strong (none are ViewSonic monitors), so needless to say we are very very disappointed in the QUALITY of ViewSonic Products.

SOURCE: My ViewsonicVP930b Monitor Suddenly Turns Off
This is a classic VP930 problem.
It is caused by bad capacitors in the power supply circuit.
Open the monitor, and look at the power board. There are six
capacitors. Replace the 220uF @ 25V and the 1000uF @ 16V capacitors. I
would recommend replacing them with 35V and 25V capacitors respectively.
If the serial number on your monitor starts with Q8H you could also
have a bad IC on the main board. Q8 on the main board is an FET in an
IC package. If this problem persists solder a wire from the right side
to the left side. There is one pin that turns the IC on and off. All
the other pins (per side) are soldered together. Do not solder the pin
on the left side that is by itself. Just leave it. Solder ALL the other
pins on the left to ALL the other pins on the right.
Remember, do this ONLY if the problem persists after replacing the capacitors AND if your serial number starts with Q8H.

Common problem in monitors are bad caps in the power supply, that is the first place to check, look for bad caps with bulging top/bottom, see example of failed VIEWSONIC monitors due to bad caps here (worst case will be bad lamps): http://s807.photobucket.com/home/budm/allalbums

The monitor shows a green light as usual then after some seconds turns to yellow. i think i have the same problem.
I have exactly the same problem. Its not a resolution issue.
My monitor powers on and off repeatedly every 4 seconds . . . the little power light on the front/side of the monitor goes on and off at the same interval. The power light on the 120VAC-12VDC cord stays on.
A vague image sort of comes on for a millisecond . . . it's not an image, but striped light and dim like it is still coming up to power, then it goes off. Four seconds later it comes on again for an instant, then off.
Note: When the screen does light up for that millisecond, I can see a small blue block of lettering in the upper left of the screen . . . it reads: 765S L7030 AU M170ES05 , or something like that.
Any suggestions ?????? Is the monitor shot? . . . or is there an easy fix?
i got the same problem but the monitor still turns off and on when my computer is turned off so i cant get into safe mode
have the same problem, but then it shows DISK BOOT FAILURE INSERT SYSTEM DISK AND PRESS ENTER
monitor wont stay on but looks fine if turned off and on again. wont stay on for more than 2 sec!
monitor randomly turn off - only way to get it back on was to power down computer. Now it will not come on at all except to show start up
I have LG W2234S and nVidia GeForce 8600 GT 1GB, my monitor turns off and then turns on repeatedly.Â
overheat? power cable? VGA cable? wtf :D
