ViewSonic VA1930wm Screen stays on for about 2 seconds, and then goes off. 1) If no computer is connected you get a "no signal" message which stays for about 1 seconds and then goes off; blue...


Very typical of View Sonic. Sounds like a back backlight or inverter. I would go to www.viewsonic.com and open up a RMA. Most view sonic screens have a 3 year warranty. They will repair at no cost ..(if it is within that period) There is a date code on the back of the screen that will help you validate the above information.

If both ends of the cable are plug in type, any monitor cable with a 15 pin D connectors will work.

Search internet for VGA cable.

Problem seemed to be a short in the power cable to the monitor. Replaced the power cable and for the time, the monitor is working correctly.

Ac power cord for HP vf51 flat panel monitor


Good Day Tricia,

I had to pull up you owner's manual to get the spec's on your cord, so if you need the manual follow this link:

http://h10032.www1.hp.com/ctg/Manual/bph08231.pdf

Anyway after reading the spec's you need an AC-DC power supply that outputs 12volts at 3.3amps. What makes this difficult to find is the 3.3amps, most aftermarket power supply only go up to 2amps. So what's next? Well you can order directly through HP at this link:

http://partsurfer.hp.com/cgi-bin/spi/main?sel_flg=partlist&model=P4824A&HP_model=&modname=HP+vf51+15-inch+LCD+flat+panel+display&template=main&plist_sval=Power+Cord&plist_styp=subcat&dealer_id=&callingsite=&strsrch=&keysel=Power+Cord&catsel=%3F
If you do this make sure get part 8121-0740 if you live in the states, or part 8121-0731 if you live in europe.

The only other suggestion I can give is to bring the monitor into a radioshack and see if they have a 12VDC 3.3AMP (you can get a universal with higher amperage if needed, the monitor will only draw the 3.3 it needs even if it is supplied more) and the reason I say bring it in is so they can match the size of the plug that goes into the monitor, as there are about 20 diffrent diameters's. Again the problem you may have is finding one with a high enouge amperage.

I hope this helps

Good Luck
