Question about Dell E153FPc 15" TFT LCD Flat Panel Monitor
I saw this problem described in another posting but the answer was not appropriate. The problem occurs after the monitor is turned on the screen last only a second or 2 and then goes very dim to the point that it is barely visible. When the monitor is turned off and on again, the cycle repeats. This occurs independent of the computer as I can pull the serial cable and get the standard "no input" color adjustment screen for a second and then it goes dim
Sounds like the back light inverter board is bad. It's a very common problem. LCD's use four small cold compact fluorescent bulbs to back light the display. (thats what gives the LCD it's brightness allowing you to see it) The inverter board runs these lights and when they go bad they will typically show symptoms like you have or the monitor power light comes on and you have either no display or a very dim display. If you ever have one that has no display but the power light is on you can check by shining a flashlight directly into the LCD from the front (right into the screen) if you can see an image then it's either the inverter board (most likely) or the CCFL bulbs have gone bad. The inverter board and CCFL's are replaceable. Good Luck, El Duderino
