Question about ViewSonic VX924 19" LCD Monitor

1 Answer

Constant switch between ON/OFF/source

I have a VX924 that worked well for over a year, but now it keeps switching between ON/OFF. It shows the image for like 1/4 of a second, with the indication Digital on the left bottom corner, then it switch off for 1/2 a second and then on again... like a loop. I?ve disconnected everything and connected it back again, and it did the same. I?ve also connected it to another PC with no success. I?ve read somewhere that this could be caused by the monitor?s built-in memory. It tries to decide whether or not to use the D-Sub or DVI input and gets stuck in a loop. If that?s the case and if there?s a way to bypass this switch I wouldn?t mind loosing the D-Sub input and fix it myself.

    My VX924 keeps switching off/on constantly. Tried to disconnect everything, did not help. As it has been posted before the problem might be with the display memory. Which keeps trying to decide over which port to use. Pls help on this, or should i get a new monitor?

    I've got a similar problem. When I came home and turned on my computer my screen was going on/off. I could see the image about a split of a second, once or twice a second. I tried unplugging/replugging all cables. I tried changing to VGA, and I tried using adapters between DVI/VGA but nothing works. Now I don't even get an image at all. Next buy won't be a ViewSonic, that's for sure. Backlight turns on and off. When I had image, I saw oscillating patterns in the upper left corner, pure white, much like how a sound sample looks like in audio editors. It doesn't matter if anything is plugged in or not, it still keeps flashing on/off and the power button blinks green/off. I can't get any menues up on it since it seems to 'reboot' before any menues pop up. I've had my monitor for 2-3 years and I expected it to last longer than that. I have given up trying on this one.

    By the way, I tried changing computers. It's not the graphics card since I tried it on a healthy laptop as well.

    same prob here, cant see the menu controls to reset. £350 for a monitor? I feel robbed by viewsonic, never again, & I suggest everyone reading this should think hard before u commit your hard earned to this company..

    Same issue, no difference. Memory recall, or factory defaults as you say, only fix the solution until the next reboot and trying them again doesn't always fix it. Is there a perm fix?

Does the menu controls work on front panel?If so you can try factory reset or Recall as it is called on some monitors.

Setting up aftermarket radio, red wire does not work, ignition fuse is not blown, how can I fix this?

What year and make is the vehicle? Could you be trying to tap into the wrong wire? The red wire on aftermarket units is usually for the switched ignition source and the yellow is for the Constant ignition source.

Viewsonic v1930wm

Sounds like the unit needs repair.

Screens shows but then gos black

Confirm that all the input cables at the back are securely plugged at the rear of the screen and PC/output source and that the image source is switched on and displaying an image. This can be done by switching your PC on and waiting five mins. Then check that the power for the screen is on. If this does not work, then let me know

I have a jvc kd-r45 it will not recall any pre set radio stations after it is switched off and demo mode kicks in every time i start it up. Tried reset any ideas?

I don't think you have the memory keep alive wire attached to a constant 12V+ source. This is why it is not keeping set stations and reverting back to demo more every time it is switched on. Usually the memory keep alive wire is yellow.

Will my b4 250.0 work with out hand held remote?

Absolutely. Any car amplifier needs only 12v constant power, Chassis ground, and a switched 12v source to power up. Your switched source is most commonly from the remote turn on lead that comes from your head unit.

VX924 (Silver, Black) 19" LCD Monitor: monitor has suddenly gone white...

My VX924 did the same thing but now displays nothing and power switch light just blinks. According to an answer listed on previous page, it may have bad capacitors. I may have to take a look at them. Viewsonic repair facility examination of this monitor runs $70.

Digital clock resets to 12:00 every time I switch off the ignition.

Have you taken the clock off? If so you might have incorrectly connected one of the leads to the wrong power source. You need to have a constant power supply to the clock for the memory but the clock light needs to be through the switch so that it will operate only when the ignition is on. If you work your way through the cables you should hit paydirt. Most source wires are the same colour as the cable of the accessory, but not always. To find the wire supplying the memory, switch your bike on and one by one disconnect the couplings reconnecting them as you go until you lose the readout. That is the one. Now you need to find a constant power source. Switch your bike off and look for a likely cable. Once you readout comes back that's the one.

ok if what im understanding is you tried on another computer and it worked great
the monitor is not your problem the problem lies with your video card
the video card could be outdated
the video card could need updated software
the video is haveing a conflict with another IrQ on *********** board this is common in computers haveing conflicts
now if your not use to computers i would suggest to take it down to nears computer tech. store and have them set your IrQ for you this can get confusing
ask them if they can show you a walk threw on how to set the IrQ incase this happens again say if you do a restore on your comp i know you dont want to pay for it again to have them fix it
or you can call "GeekSquad" they can come to your home and fix it for you and show you a walk threw this might be better for u
i hope this helped you alot

My VX924 problem (basically the same as many other peoples)

This is the way how to examine where the problem is. You have to check that you can see the image on screen by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely when the monitor is off. If you can see the icons (Power on both cpu and monitor), there will be a minor problem. Like me, I can see window image using flashlight and check lamps inside. Some of them were broken and it can be easily replaced. If you cannot see any icon on the screen. I would say that there are some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or burning spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so.

My ViewConic Monitor has exactly the same problem as this another post? HELP!

Does it come back if you lower the resolution to the lowest and make sure the refresh rate is at 60 Hz?
