Having problems with your Westinghouse L2046NV Monitor ?

LCD Monitor. I get a power light that goes to green then a quick very light flash of light on the screen, then the screen goes completely dark. I can not see the image with a flashlight as other posters have mentioned. Steady green light stays on. I've pulled the back of the machine and all of the caps look okay.

Hi\015\012
\015\012
\015\012Thanks for using FixYa. If the capacitors look fine then check for the power out put from the power board to other boards and to the back light inverter. I'll also suggest you to check whether the top of the caps are bulged or not & the resistors connected with the caps are also fine. You'll need a multi meter to check all of these. \015\012
\015\012Make sure that the cooling fans inside the monitor are working. If there is not enough power output from the power supply board you'll need to replace it.\015\012
