I have a v173 lcd monitor by Acer. Suddenly yesterday the screen went dark. The power seems to be working as the blue light for the power button is "on"/lit. When hitting the power button the screen displays my home page for a brief second or 2 then it goes black. Can you please provide me with some assistance i.e., if I can fix it myself or it needs servicing. Note: all cables - connector and power adre in place. THANK YOU

I have a v173 lcd monitor by Acer. Suddenly yesterday the screen went dark? This trouble maybe power supply or inverter boards is defective.
first you can test the voltage of the multr,and then check which part is defective.From Wisiny.com can find those parts
if you have any question,please let us know email:[email protected],we sincerely hope we can help you!
you can also check this boards whether suit you:
9721AQKM 715G3350 1 3 Acer ADTV9721AQKM Power Supply Backlight Inverter

You need to check the fuse (round black component next to the small green circuit board as shown on the left of the picture), DC filter caps for domed tops, DC voltages. Tho have to fix will not be worth it. The problem is more likely to be the small circuits board (on the left of the picture).
