Probably 1280 x 1024 at 32bit color depth assuming those are the settings you are asking about. If not, please be more specific with a follow up post.

The screen goes on for a second and then turns off. If I then turn the power on and off numerous times it eventually stays on. I put the screen off to 60 minutes. Every time the screen is allowed to turn...


Hello Geoff,

The problem you are having is caused by a power supply board that is failing. Your monitor uses the Delta DAC-12M033 power supply board. We have a repair guide for the Westinghouse LCM-20V5 monitor that uses the same power supply board posted o our web site at: http://www.ccl-la.com/blog/index.php/repairing-the-westinghouse-lcm-20v5/ Check out the web article, it should get you back going again. If you don't want to do the repair yourself we do offer a repair service. We can get deatils on this service here: http://www.ccl-la.com/blog/index.php/service-request-form/

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

My Viewsonic VG2021m Monitor recently cut out every 5 or so seconds (the display came up and then went off) again and again and now it seems as though i cant turn it on at all even though the blue on light...


Hello,

The intermittent image, dark picture or no power are all indications of a failing power supply. If you can solder you should be able to repair your monitor. We have an article posted on our web site at: http://www.ccl-la.com/blog/index.php/repairing-the-westinghouse-lcm-20v5/ The post is about repairing the Westinghouse LCM-20V5 but they both use the same power supply board, the Delta DAC-12M033 so the information is the same. If you don't want to do the repair yourself we do offer a repair service for this model for $32 plus return shipping. More information on this service can be found here. http://www.ccl-la.com/blog/index.php/service-request-form/

I hope this information helps, if so please rate our solution.

Hello,

You have a monitor with a failing power supply. The Viewsonic VG2021M monitor uses the DAC-12M033 power supply board. After several years of use the capacitors in the power supply start failing and not keeping a charge. The capacitors are on the output side of the power supply and help filter and stabilize the voltages. When they fail the power does not settle when you turn it on so you have to do the on/off/on/off to get it to start. If you can solder then you should be able to repair your monitor. Check out the article on our site at: http://www.ccl-la.com/blog/index.php/repairing-the-westinghouse-lcm-20v5/ it is for the Westinghouse LCM-20V5 but they both use the same board so the repair information is the same. If you don't want to do the repair yourself we do offer a repair service for this unit, it runs $32 plus shipping. You can get more information on this service here:

Does not power up freind thinks it's a blown capacitor


Yes, it can be that and other components.
Most common failure in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, 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 WESTINGHOUSE (LCM-20V5 may be thesame chssis as yours) and monitors to get some ideas what goes wrong: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further.

Screen goes black after fraction of a second


More likely to be bad capacitors in the power supply, see LCM-20V5 (almost the same chassis as used in LCM-19V5) example: http://s807.photobucket.com/home/budm/allalbums

Post back what you see insdie so we can guide you further.
