Dell 1704 FPTt monitor goes black after about 20 min

viewsonic va1703w screen is starting blur and it is changing colors Screen goes black or pixelates and after 15 to 20 mins by pressing the power on button of the monitor it is getting switched on, and again when restarted it is having the same problem.

Isolate the problem per above. Eliminate the monitor, split cable and software settings so that each, individually work. Then eliminate team board - do you have a spare?
It could mean sharing the monitor signal means weakens it so that one can display and the other does not work. Prove it with a different source computer. Don't know if buffer devices exist or how to increase input sensitivity.

try running it in safe mode tap f5 when you see the dell screen. if it boots to safe mode remove the driver for the display adapter in device manager. the dell computer doesn't know what kind of monitor it's plug into. install the soyo monitor driver

Hi my name is Rain.
Ok so that im clear on the problem. your monitor will come on but in a matter of seconds it goes to a black screen?
If this is the problem. The answers you seek will most likely
be in your video card.
Try this test:

• Unplug monitor from the computer.
• Turn on monitor .
• Look for monitor self test screen.

If you see the monitors self test screen then your problem indeed is
the video card . You will need to replace the video card inside of the computer.

well i have a dell 22'' monitor and it did exactly the same thing , turns out its a fault with the invertor drive transistors ( these power the fluro screen light ) , i'm in the uk , but i would take it straight back to walmart along with proof of purchase and tell them it dont work and ask for a repair /replacement under warranty

Hello,

You have a monitor with a common problem. After a few years some LCD monitors will blow a power supply. The problem is caused by parts called capacitors overheating in the confined space of he monitor. If you are good at electronics repair/soldering you can usually fix he problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htm You can take the back cover off your monitor and look for the badparts, replace any that look like the pictues and your monitor should work fine. The capacitors do need to be installed with the correct + and - connections, note the stripe on the old one and insert the newone the same way. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping. I hope this helps, if so please rate my solution.

This might be related to your system power options, if your monitor turns off after sometime (20 mins in this case) the best way to find out if this is caused due to a thermal reason - is to see if the monitor can work immediately after it turns off (coz, for thermal shutdowns it needs time to cool down before it works again)

go to control panel>power option>power scheme.
adjust the hard drive to 30 mins and everthing else 20 minutes.
also, go to display and adjust the screen saver to be longer. up to 9999min.

There is a good chnace your Backlight bulbs need to be replaced.
