Question about ViewSonic VA720 17" LCD Flat Panel Monitor
Your power supply is having a problem starting up. This is a common problem on LCD monitors after 2-3 years of use. The heat build up in the case causes parts in the power supply called capacitors to blow out and short out the unit. If you can solder then you should be able to fix it yourself. Go to our web site at:
www.ccl-la.com/badcaps.htm and look at the pictures of what the caps look like when they blow out. Open the back of your monitor and replace all of the ones that look like the pictures and you should be back with a working monitor. The values you need to purchase will be marked on the sides of the blown caps that you take out. Be sure to get low ESR and high temp 105c replacements or you will be back doing the repair again in a month or two. The capacitors from Radio Shack will not work.. The replacements can be ordered from several places on the internet or we can supply them for you. When you install the replacements be sure to insert them with the polarity stripe on the side going the same direction as the old ones when going. If you don't want to do the repair yourself we do offer a repair service for $30 plus return shipping.
I hope this helps, If so please rate our solution.
