Backlight


Broken LCD monitors basically come in three categories:
1) Cracked LCD panel, rendering the unit completely worthless
2) Backlight problem
3) Power supply problem

If it's a backlight or power supply problem, it can be fixed.
Usually, the problem stems from the high voltage inverter circuitry, either bad power transistors, capacitors, or thermal stress on the circuit board leading to broken solder joints.
But fixing these problems can often be a short term solution. The bulbs themselves have a limited lifespan, and the high voltage power supplies are prone to failure.
The panels themselves almost always outlive the backlights and high voltage power supplies.
The 17" Dell LCD monitor I found was no exception. When I first plugged it in, it would cycle power on and off continuously, with a notable burning smell. Further inspection revealed a fried power transistor. When i replaced it, the monitor stayed on, but the backlight would flicker on and off, then finally shut off after a few seconds..
The panel was good, but trying to fix the backlight with the proper parts wasn't really worth it.

But maybe I could still save it, or even make it better. After all, it's just a light. Lights should be user-replaceable things anyway.
I mean, a Lite-Brite was the cheapest toy, yet you could at least change the bulb.
So here's the result of my experiment, with help from an old CRT monitor:
Step 1: Go to trash, locate a CRT monitorfeuoxynfkof7iwm.large.jpgTake a CRT monitor, remove the guts and dispose, keeping just the shell and monitor stand.

Install a light bulb socket about 1/2 way back. I used switching socket from an old lamp.
(for the bulb, I used a 60w-equivalent "daylight"/6500k CFL bulb. It has a blueish glow to it. )Step 2: Cutout back of LCD monitorf4mg1hnfkof7ixd.large.jpgf4mg1hnfkof7ixd.large.jpgpixel.pngf4mg1hnfkof7ixd.medium.jpgFor the LCD monitor, cutout the back and remove the metal shields/ PCB's behind the panel, allowing light to pass through it.
(This step varies a lot from brand to brand. Some brands will have ribbon connections on both the X and Y plane, while some just on the X plane. Fortunately, for my Dell monitor (which was actually a BenQ monitor), the ribbon connector was only on the X axis, so lifting it out of the way to allow light to pass through was easy, without requiring any extra wiring. )

For the panel light filters, there should be some diffusing paper/plastic behind the LCD, 3 sheets (one clear, one reflective, one translucent white), and then a large Plexiglass-like filter. I removed the Plexiglass and everything behind it, only keeping the 3 thin paper-like sheets behind the LCD. Shining a light behind the LCD resulted in an even white glowStep 3: Mounting the LCDfe393blfkof7ixx.large.jpg4) Relocate the boards from the LCD panel to the CRT shell, mount LCD panel, and connect everything up. For mounting everything I drilled holes and used zip ties.Step 4: Resultsf8h4e6rfohxaofc.large.jpgSee my project page for more pictures.

Conclusion

This LCD was saved from the trash.
And now if the light ever goes out, it's easy to change. Also, as a bonus, the monitor vents glow, partly illuminating the desk and keyboard at night. Shouldn't all monitors be made this way?
:-)

Notes

LCD Monitor is a Dell E172FP.

When the monitor is off and the light is on, the display is more transparent than black, sort of a light/mid gray.

There is some minor hot-spotting, but not very serious. Given the type of cheap hack this is, it is more than acceptable.

Obviously, the monitor is more bulky than it used to be, but very light. Almost half the weight of LCD monitor as it was before.
Bathroom scale says it weighs 7lbs. (original LCD weight was 13.25lbs)
Gettting rid of the LCD's metal frame, stand, and heavy plexiglass light filter was the major contributor to the weight reduction.
The CRT's shell and base are just plastic (with some springs).

The LCD frame was smaller than the CRT's. I just cut out some cardboard to fill in the gaps to block out the light for now. I know, it looks ugly. Later, I'll make a better looking frame.

After you turn it on it goes to a black screen, then wont turn off.


first check the supply of the LCD monitor check the plug supply usually 110V or 220v use a voltmeter, if the voltage is present look for the indicator lights that is changing when power switch is press,the indicators tells you if the problem is in the power supply area of the LCD monitor or in the screen, usually the problem with the LCD monitors is in the screen check the bulb on top of the monitor check if it is not function well this bulb is responsible for the brightness of the screen if it is defective replace it or maybe the supply of the bulb is defective you can use the power supply of the cathode light as a replacement to its supply that is usually use in motorcycles signal lights.. hope this helps you..

Still having a problem with the monitor


It sounds like you get this problem even when you are sitting there using the computer. If this is the case then there is a problem with the hardware inside the monitor.

Unfortunitally it's something that you would have to have DELL fix. It will involve sending it to them for repair if the monitor is still under warranty.

Dell SE198WFP 19" LCD won't come out of standby


I went into the BIOS (with F2 during restart) and changed a value -- IIRC it was called something like "power management scheme" -- from the default S3 to the other choice, S1. Now the old Dell XP Dimension 2350 will go into and out of Standby correctly and the new SE198WFP 19" LCD will too.

Dell 15 inch lcd monitor issue


The first thing you should do is change the monitor for another known working monitor to make sure it is the monitor that is faulty and not the video output of your computer.
