The inverter is the most common item to fail on a LCd monitor. Capacitors usally fail the most. Are the tops of any of them popped up. If you had any shorted transistors the fuse would probably be blown. Usally labeled F1. I would replace all the capacitors first and go from there. Capacitors are cheap.

Our TV shut off and won't turn back on. We have had it unplugged since 12-27-14 around 4:00pm and we plugged it back in 12-28-14 and it's still not turning on. Any suggestions?
If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

Asus Monitor
Here are a few possible problems with your monitor
1, Backlight gone bad
2. Power Supply gone bad
3. Wrong display resolution
Given that your monitor is only 14 months old, I would lean toward
either a bad capacitor in the power supply or the screen resolution
needs to be changed (boot up in safe mode and change the resolution)
The power supply problem would require some dis-assembly and working with high voltage.Not for the faint of heart..

I have a 710S 17 in. Microtek monitor and everytime I try to change the resolution to anything bigger than 800x600, the screen turns black and says "Out of Range". What can I do to fix this?
this monitor max resolution is 1280 x 1024, are you trying to go higher than this?
If not, then you kay have unstable DC in the power supply due to bad caps.

I have a microtek 710s monitor, that powers on but
Most common failures 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 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.
