Question about Dell E151FP 15" Flat Panel LCD Monitor

1 Answer

Backlight goes out

Backlight operates 1 or 2 seconds on power-up or when performing auto adjustment, then goes dark. I'd be happy to replace a capacitor if I knew which one to yank!

You probably have a bad inverter.

the backlight is either going out or the capacitor for the backlight is bad to where its not storing enough power to run the backlight the start capacitor must be good but the run capacitor might be bad usually the backlight itself goes bad but not if it turns on for a few seconds it would have to be the capacitor.

guess there is an larger issue with your notebook.....
you need to get the backlite changed, if you have chanaged the lite then there is a compatibility issue with the screen and the invertor board that's behind the LCD screen.
or the system is not supplying the correct current to the backlite / invertor board

a HW tech guy may solve your issue

Laptop toshiba satellite p200 bw5 screen goes dark as if darkness/brightness was adjusted - but not Thanks


An LCD screen cannot produce enough light by itself. It needs a Backlight to help illuminate the screen.

Power for the Backlight is produced by an Inverter. An Inverter also provides power for the LCD screen.
It reduces voltage for the Backlight, and increases Voltage for the LCD screen, from the laptop's power.

Most of the time a dark LCD screen can be attributed directly to a bad Inverter. (Around 90 percent)

A Backlight is a CCFL.
Cold Cathode Fluorescent Light.
VERY similar to the fluorescent lights you see used in residential, and commercial applications.
(Homes, and businesses)
Only on a MUCH smaller scale in physical size, and needed power to operate.
When a Backlight goes bad, it just goes all at once. Not goes dark as you have stated.

(Your statement meant to me that you power on the laptop, the LCD screen shows well, then goes dark)

NOTE*
1) ALL power removed from the laptop before beginning.
AC adapter (Charger), and Battery.

2) The screws you will remove, may have screws that look alike, but are NOT.
Do Not mix them up.
For this reason it is suggested to use a multi-compartment container, and label the compartments for where the screws came out of.
You can use a clean egg container, and label the individual egg holders, in a pinch.

IMHO it isn't hard to perform this repair, and you can do it. Save yourself money.

Dark Screen even when i adjust the 'brightness' tab?


check the power settings on te unit, if it is set to default for the backlight, possible that your LCD's backlight is not powering up properly on the unit or LCD's backlight needs replacement.

Dell ADAMO 13 w/Vista 64 Random power failure...goes dead in 1 second. Battery fully charged. Happened with external power and when on battery. I have latest BIOS v6.0. I ran pre-boot diagnostics...


If the power totally fails (i.e. power is cut off, LEDs turn off, fans stop, ... etc), then this more likely to be because of a short circuit developing in a failing semiconductor component, or a power supply problem.
However, if the laptop is still running & only the display on its LCD is cut off but the laptop itself stays powered on, then your laptop might be experiencing a failing screen inverter board, a failing screen backlight lamp, or a failing LCD screen cable.

TYPICAL INVERTER FAILURE SYMPTOMS

1. When you turn on the laptop, the screen lights up for a short period of time and then goes dark. You still can see an image but it is very dark, almost invisible and definitely not usable. When you restart the laptop, the screen lights up and then goes dark again. The laptop works fine with an external monitor.
2. Your laptop turns on but the screen remains dark all the time. You still can see a very dim image outline. The laptop works fine with an external monitor.
3. The laptop screen works fine for hours or even days, but sometimes it goes very dark as it mentioned above. When you restart the laptop, the screen works fine again.

Inverter failure symptoms are very similar to backlight lamp failure symptoms and in most cases you cannot tell which one is causing the problem until you replace either the inverter board or the backlight lamp. From my personal experience, inverter boards fail more often than backlight lamps. If you have to guess, replace the inverter first.

Monitor picture goes extremely dark


sounds like the backlight is defective. You can probably get a new backlight online if your comfortable taking apart sensitive electronic equipment BUT you must be very very carefull and handle the lcd with care as you can easyly damage it. Oh one more thing the power supply may also be defective for the backlight. I would contact the manufacture to see about the repair or replacement parts as they should be listed in your operators manual. Good Luck
