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 (they should be replaced in a set), 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 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.

Goes dark for 5 to 10 second for no apparent reason?


Look for bad caps in the power supply, it will get worst and can take out the inverter fuse and the MOSFET.

Hello,

One of the button across the bottom of the monitor is stuck. You need to just move the buttons on the bottom around a bit and then power it back on. Your problem should be corrected.
