You can get these on EBay.

There is a chance that you may have a couple bad capacitors on the power-inverter board but more than likely the problem will be a shorted out transistor. There are 4 on the inverter side of the board and one set may have gone bad. Capacitor problems may have caused the transistors to fail. Transistors are probably c5706 or c5707 and are black with 3 legs going though the board.
You would have to open it up to check and would need an ohm meter to verify if the transistors are shorted out.

More likely to be transistors.

Check the solder joints, fuse, transistors (c5706/5707), caps and look at other Dell albums also.

On E152fpb dell only replace all driver transistor the c5706 or c5707 this 2 types of transistor is not desame one is PNP & NPN so you must be careful of replacing component maybe it will help you

Check for shorted out transistors (4, c5706/707) in the inverter transformer driver circuits.

It is more likely to be bad inverter cicuits due to shorted out transistors (four c5706/5707). The power light blinking?

Look for shorted out transistors (four, c5706/5707) in the inverter backlight transformer driving circuits.

First, check the 4 transistors (c5706/5707) in the inverter transformer driving circuits, then also look for bad caps. See example of failed monitors here: http://s807.photobucket.com/home/budm/allalbums

Check power supply for bad caps, check transistors (C5706/5707) for shorts in the inverter circuits.

Check for shorted out transistors (C5706/5707) in the inverter circuits.
