Question about ViewSonic VX924 19" LCD Monitor

3 Answers

Blinking On/Off.. seems to be a common problem.

I've had this monitor for about a year and a half, and haven't had any problems with it up until yesterday. All of a sudden the monitor turns off, turns back on, and continues to do this. The green power button light turns off and on with the monitor. I only get a split-second flash of the screen before it turns back off, making it completely unusable.

This seems to be a huge problem with this model. A few solutions I read mentioned replacing capacitors inside the monitor. Has this worked for anybody at all? Would I have any luck taking it to a computer repair store, or should I just buy a new monitor?

    same thing happen to mine... comes on and off again and again... have u found the solution ? care to share ?

    Same problem here and it's getting worse..(lost counting at 600 "blinks")
    My Viewsonic is bought in january 2006 so unfortunately the warrant for
    vx series is out of date.(purchased before the 1st of April 2008 = 2 years)
    Someone mentioned that the inverter board (whatever this is) could be the problem. I've e-mailed Viewsonic Europe (where I live) but haven't got an answer. I wonder: is it worth take the monitor to a repair shop or
    is there a market for this kind of spare parts and is it possible to fix?

    Same problems here. There seem to be more and more blinks until my monitor stabilizes as time goes on....

    Any solutions yet?

    I have a VS10162 and it seems to be showing the same behavior. I am using an older analog video card. The problem is getting slowly and progressively worse. A newer card (presumably with higher output voltage) seemed to help, but I still get the issue when adjusting display resolution settings (when the display goes off it does not always come back on). I figured out that by holding the power button down when lighted, I can coerce the monitor back on.

    Yeah I posted the similar problem about my monitor.

    I wish I had someone repair that for me for free LOL since mine isn't covered by warrenty. I am afraid to open up my monitor to make it "worse"

    So I have no idea or why the monitor stops showing the normal colors!

I replaced the two 470 uF capacitors on the power supply inside the monitor. They were puffed up / burst. Now it works great.

Just replaced the large cap (100uF @ 400V) and problem has disappeared ! It was in fact open circuit. Nice to have it stop flashing ! :-) Stu

I just replaced ALL of the Electrolytic Capacitors (6 in all) on my bad VX924 P/S, and it did not help. Several of the old caps were puffed-up/burst. I am ordering a new power MOSFET, Q320, if successful I'll be back in touch.

My monitor MAG lcd 16inch turn black i change all the capacitor 6 pcs 470uF 25 volt same problem again help me Thank you


In case you haven't done it already, please connect the monitor to the computer and turn everything on and let it boot up. While the screen is black, take a flashlight and carefully hold it against the screen. If you can see that the LCD portion of the screen is working, then continue reading. This model seems to have a number of complaints against it. That being said, many people seem to believe that caps become swollen just because that's what they do. In my experience, for multiple caps to swell or need replacing, it takes a long duration over-current event or a short duration death event. The most common long duration over-current event in a monitor is burned bulbs and/or burned transformer. The most common short duration death event being a power surge (blackouts, lightning, or connected to the same breaker as an air conditioner or microwave) If you have successfully replaced the caps, then you already show some technical prowess. Search your main board model number for some more info. If you can read the tiny part numbers on the transformer, search for a datasheet to find a way to test it with a meter. Bulbs are a bit harder to do. I've done it, but it is almost impossible to keep even a single speck of dust from entering the insides. If you get to the bulbs, and they are blackened on the ends, you can be fairly certain that they are burned and creating an over-amp condition in the driver circuits. Best of luck to you.

Nothing on screen, gren and orange light flashing


You more like have bad capacitors in the power supply. Open it up and look for capacitors with bulging tops. http://en.wikipedia.org/wiki/Capacitor_plague

Hello,

It sounds like you have a monitor with a common problem. After a few years some LCD monitors will blow a power supply. The problem is caused by parts called capacitors overheating in the confined space of he monitor. When the capacitors blow out they also damage the driver MOSFETs. If you aregood at electronics repair/soldering you can usually fix he problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htm You can take the back cover off your monitor and look for the bad parts, replace any that look like the pictures and your monitor should work fine. The capacitors do need to beinstalled with the correct + and - connections, note the stripe on theold one and insert the new one the same way. If you don't want to trythe repair yourself we offer a repair servicefor $35 plus shipping.

I hope this helps, if so please rate my solution.

If the monitor does not have any bad caps then I would be that when the video card died it sent a spike to the monitor and killed the driver board. I hope this helps, if so please rate my solution.

If you know how to open it up and get to the power supply you will find three capacitors 2-820uf and 1-330 @ 25vdc 105o.they will have puffed up tops replace them. FYI the monitor has a 3 year warranty.

Moniter won't turn on/power light blinks green


Yeah, I called Dell yesterday, and they said it was a problem that I could not fix myself. Whether that's true or not, I don't know, but my monitor was still under warranty, so they shipped me a replacement right away. I already got it this morning. 

FYI: Their monitors carry a three year warranty.
