I RMA'd this probablem as well. They asked the usual questions -- try it alone, check the connections, are you using VGA or DVI... blah blah. Eventually they could give me an RMA.

They have customer support via phone on Sundays in the US, which is nice. Total time from calling to RMA was about 20 minutes.

You need to isolate the problem to see if there's a problem with the monitor or with the sound card of the computer.

To isolate this problem, please try the steps below:

1. Make sure that the monitor is properly connected to the computer.
2. Check the volume of the monitor and the volume properties of the computer.
3. Try to connect your monitor into a known working computer.

This is indicative of either / or CCFL back lamp or inverter.

The CCFL is a Cold Cathode Fluorescent Lamp and the inverter changes DC to AC and functions a lot like a ballast for the CCFL. You'll probably end up buying both - unless you know for sure it is the lamp or the inverter ahead of time.

Prices vary on size of lamp, etc. Most suppliers offer both the lamps and inverters and have pages to assist selecting the correct CCFL & inverter online - one such is here. There are others, too.

Please rate my reply - thanks & good luck!

Hi I have a viewsonic VX922 which I have replaced the caps but on ressembly I can't remember which way round the four back light small plugs go. Can you please help. Thanks Peter


If the capacitors are polarised electrolytic type then they have a + and - leads. The - lead is marked on the capacitor with a stripe and a - sign. The circuit board where the capacitors are located will be marked with a - sign, make sure the capacitors are located correctly acording to the markings.
You need to put the capacitors with the correct values (capacitor) in the correct place on the circuit board.

If the capacitors are non polarised type the it does not matter which way they are inserted on the circuit board, but they have to be the correct value (capacitor).

LCD FAILURE


More likely the power supply/inverter board may have failed due to bad DC caps which happen after about 2~3 years.
http://www.shopjimmy.com/power-supply-unit-200-000-170dtlbmh-from-viewsonic-va1930wm-2.htm

If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed Viewsonic and all others monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Having trouble powering up my Viewsonic VX922. See the analog data, but have to power down for 20 sec (several times) to get the digital data on the screen


bob_loopeker, If you know that your pc is ok with different monitor then you will need to inspect the power supply board inside your VX922. All you need in the way of info is here on fixya!! All you need to do is read and make decision on what to do. Spend some time reading in my fixya profile or do "ctrl" key and click on "vx922 19" monitor" that is highlighted in light blue text above. May need new capacitors installed on unit's "switch-mode-power-supply" printed circuit board. hopre this helps. 12fixlouie

Green light flashing on and off and computer screen will turn on when feels like it


The flashing green power button is a well known electronic problem with this (and other) Viewsonic LCD monitors. There is YouTube video (do a search) showing how to disassemble the VX924 (very similar to the VX922) and find out whether the problem is related to blown capacitors. When I took my VX922 apart I discovered 6 bad capacitors out of a total of 7 on the power supply circuit board.

My monitor is getting off


I have a similar issue. A search at Tomshardware web site suggests that faulty capacitors are the issue and that this is a widespread problem certainly with the VX922. Several guys on the Tomshardware post claimed that replacing the capacitors solved the problem (their units were out of warranty anyway).

Viewsonic VX922 19" Green Light Blinks when booted, no picture


I have the same problem with my VX922 as do MANY others. The problem seems to be caused by leaking/bulging capacitors on the circuit board. The only solution is to replace the faulty capacitors either on your own (which is fairly easy if you're good with a soldering iron) or send it to Viewsonic and have them fix it.
