Monitor powers up momentarily and goes to standby normally with no video connected to it, but while its on, it lights up bright white, which does not appear to be a normal mode. Also, sometimes video is fine, but in most cases, the presence of a video signal from the PC's VGA connector to the monitor causes the power to the monitor to shut down completely. It is not going into standby; its going completely off (the power LED is completely dark). The monitor cannot be powered on while connected to the PC's video output, no matter how many times I press the PWR button. Now, if I disconnect the monitor from the PC, it turns on (LED green, white background) then goes to standby. Please note: the PC is NOT the problem, is OK, and works with its usual flat-tube monitor connected. The problem is completely with the ViewSonic VE710b. This is a good one, so please DO let me know if you can help me with this before I give it to my youngest son to tear up!!
I fixed this problem by replacing all the electrolytics 1000uF and 1500uF on the power supply/inverter board. All were either bulging or had burst at the bottom rubber seal. This cleared up all problems and I am using this monitor successfully at this very moment.

The message says that the monitor doesn't receives signal - which is normal. Since the problem appears only after you plug in the cable in means that the problem is located there - something is wrong with your pc, most likely the video card has died.
If the monitor is going into sleep mode the normal power led will change to another color. This indicates loss of video signal or possible out of range resolution. If the picture goes dark and the power lite stays on, you have a backlight malfunction. It can be bad capacitors causing an inverter power fault or it may have worn out backlights causing a shutdown condition. Monitor Mike
1.) Your video card is 'stuck' in standby mode, which in turn sends a signal putting the monitor in low power 'standby' mode as well. When you disconnect it, the monitor returns to normal 'on' mode. Rebooting the PC should correct this issue.
2.) Your resolution or refresh rate are set outside the range supported by the monitor. When you connect the monitor, it starts receiving a signal that it can't display, so it simply turns off. You'll need to reboot the PC and press F8 quickly to bot into safe mode and correct the monitor settings.
I'd try this monitor on a spare computer. It sounds like the video card (motherboard integrated or otherwise)is not putting out any video information or missing sync signals. The monitor must receive these signals or it will go into standy/sleep mode.
If the computer has integrated (on motherboard) video, check your bios settings to see if it is properly enabled. If it has a slot video board, then try a different video board. Your present board might be dead.
Another possibility is a bad cable connection. check the connectors for bent pins. Assuming the connector is the standard HDB-15, it is easy to bend a pin over.
