Re: H 170 L-17" monitor
If *nothing* displays on your screen, the most likely problem is your LCD Backlight Power inverter. If the backlight power inverter is bad, you can usually see some remnants of an image on the screen if you shine a light on it. If the backlight power inverter is bad, it may not be worth repairing on a 17" screen, considering the low cost for a new one.
It should be noted that Envision provides a 3-yr warranty for most LCDs, so contacting them for repair may be a good option. More information here:

HOw about the light on the tower? if its stedy green then the tower is ok then run a self test on monitor if it passes the monitor is also ok then unplug the power cable from the monitor and data cable also and press and hold the power button for 10 sec and then connect the monitor to the system
double check that all yor connections are tight. Open your PC case (unplug it) and ensure that all your fans are clean. It appears that your problem is due to loose cable connections, but this may be a good time to do some computer spring cleaning.
I had the same problem for about a week and solved it yesterday by
downloading the latest driver by NVDIA who makes my video card (NVDIA
I had previously updated the latest Sony driver for the monitor. It did
not solve the problem but could be part of the solution in conjunction
with the new video card driver.
I had the problem sometimes, but then I connected a second computer to the analog input and found out, that the screen didnt turn black but switches between the inputs on an on.
I found out that the "input" button seems to be short or damaged, as the behaviour was invertable by pressing the button. I blew into the button some times (a very naive solution, yeah) but it worked, the switching stoppped.
ccfl ( cold cathode flouroscent lamp ) is the backlit feature of the lcd panel.
If you see a blank screen but do see the output on the external monitor then you sure have to take it to the hardware tech to get the inbuilt LCD panel checked.
it seems to be a electronic failure.
