Question about MPC Computers Envision EN 7100s 17 in. Flat Panel LCD Monitor
NO.. Do not replace the LCD panel, nor the chip that controls the backlight (there is no such chip anyway), nor the backlights themselves, as none of the above are broken.
There are some capacitors on the low-voltage side of the internal SMPS. One or more of them is bad. Most likely, you will be able to see bulged tops on them. Replace them with identical uF rating and same or higher voltage rating, making sure to get the polarity correct.
About the only CORRECT thing I've seen in any of the other replies to this post is that the problem is common among many LCD monitors. I've personally repaired five of them in the last three days.

Had exact same problem........
Pharkus was right on. Replaced the 1000uF 16V and the 470uF 16V caps next to the largest/yellow transformer. One at the top and one to the left. Works like new!!!

This problem is common between a multitude of lcd's i am pretty sure that it is either a lcd bulb problem (mini floresent) or the chip inside the monitor that corrects the amount of power the bulb gets. I have replaced bulbs for these and it has fixed this problem.
