Viewsonic VX2245WM blue light turns on indicating power, but screen is black, capacitors look fine


If the capacitors look good then the most common cause of black screen on this unit is the MOSfet driver chips and the 4amp fuse. The driver chips are the little black squares at the top of the board with 8 legs. They are part number AOP605 The 4amp fuse is located on the bottom of the board and usually has a "W" printed on it. The fuse is very small, about the size of a grain of rice.

The repair would require replacing both chips and the fuse. The parts are available here:

Almost the same chassis as VX2235.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, 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 VIEWSONIC monitors to get some ideas what to look for:

Blue power light is on but screen remains black

Common problem with 2235/2245 is failed capacitors in the power supply/inverter board combination. You need to get the P/N and names of the board since there may be more than one version of the assembly for the same model.
When you get the information, then you can check here:

I have a Viewsonic VX2245wm or VS11349, Works and then it goes black for 2 to 4 sec then runs for 10 to 15 min and goes black

Look at the power supply section for bad caps first, see example of failed VIEWSONIC monitors due to bad caps:

I have power going to my Viewsonic VX2245wm but no image

You need to check the internal power supply to see if your capacitors have popped. Even though it may show power, the portion of the power supply that powers the LCD itself may have been damaged ::
