Primer:

An LCD screen does not produce light,

http://solutions.3m.com/wps/portal/3M/en_US/NA_Optical/Systems/BehindTheScenes/Optics101/

Click on the monitor icon

Because of this the LCD screen needs an additional light source.
A Backlight is the additional light source.

A Backlight can be a CCFL, (Or more than one), or a series of LED's.
(Light Emitting Diode)

CCFL = Cold Cathode Fluorescent Lamp (Bulb)
Similar to Fluorescent lighting used in homes, and businesses; but on a MUCH smaller scale.
Average thickness is 2mm, or a little more than 1/16th of an Inch.
Or about the width of this capital letter -> O <-
Average length is almost as long, as the LCD screen is in height.

OH, YES!)

A screen Inverter is used to convert the power from the laptop, for the LCD screen, and Backlight.
If the laptop uses LED backlighting, it MAY or MAY NOT use a screen Inverter.
Generalized thinking (Can also be stated as 'Rule of Thumb'), is that if the laptop uses LED backlighting, it does NOT use a screen Inverter.

I also feel into this line of thinking, since none of the LED back-lit laptops seemed to use a screen Inverter; that came to the shop.
I have found this to be a fallacy from on here,......FixYa.....
I have looked up two laptops using LED backlighting, and discovered they also used a screen Inverter.

Now I post LED backlighting may, or may not use a screen Inverter.
Seems when LED backlighting first came out, a screen Inverter was used on some models.
Also seems as the LED backlighting technology progressed, no screen Inverter is used.

90 PERCENT of the time, the fault for bad Backlighting can be attributed to a bad screen Inverter.
Of course, this IS IF the laptop uses a screen Inverter.

For a laptop with LED backlighting that does not use a screen Inverter, and backlighting is bad (Dim, or non-existant), the next hardware part in the diagnoses to replace, is the LCD screen.

I now await the information I asked for above.
Then we can diagnose together.

No backlight


A) Replacement LCD screen backlight could be bad.
Happens. Sometimes you get a bad part. (Bad LCD screen assembly, in this case)

LCD screen may not be the correct one.

A screen Inverter, and an LCD screen; are a MATCHED unit.

B) Screen Inverter:
May be bad, or the Wrong one

C) You may not have the screen Inverter, connected correctly to the Backlight.
Connections aren't tight.

D) The Display Cable TO LCD screen connection may not be tight, or correctly connected.

I know the display shows graphics, but a poor connection of Display Cable to LCD screen, can make the Backlight dim out.

I'm betting it is a poor connection, or the wrong screen Inverter, or wrong LCD screen.

Sound but no picture just 1year old


This looks like a problem with the inverter/backlight.
Turn on the set. (Take a quick look at the backlight setting in the menu just to be sure)
Take a bright flashlight and place it against the screen. Look around the edge of the flashlight for a moving image. This would indicate a bad inverter. The inverters supply voltage to the fluorescent backlight.

IF you know how to work on electronics you or a friend with knowledge/skill can replace the inverter board. You did not give a make and model so I do not know the part number.

You can look on www.shopjimmy.com, eBay, http://www.tvpartsandmanuals.com/
for an inverter board.

The screen is dark but i can see the desktop icons


The backlight is out - two causes. The Inverter is bad or the backlight florescent bulb itself is bad. You can check the inverter by plugging in a know good lamp to its' output. Becareful because it produces a very high voltage enough to shock you. Usually, the inverter goes out. You can connect an external monitor to the VGA output and see if produces an image. If it's good, more than likely the above components are bad and it's not the motherboard.

This doesn't necessarily rule out the inverter. I've had inverters with intermittent problems that had the same effect, so having the inverter tested is the only way to rule it out. Other possibilities are a bad connection, a corroded/dirty pin or socket in a connector, a bad ribbon/cable, and a failing backlight. If it is a failing backlight, the entire screen will need replaced, as the screen is considered a sealed unit and the backlight isn't available and not considered a replaceable item. Also, it's rare, but it could have a faulty motherboard component or video card. I'm leaning towards a faulty backlight, but keep in mind the inverter and cable possibility. Start by checking and cleaning all connections.

Insignia NS-32LCD Backlight or Inverter bad???


If you've done the flash light test, it could be the inverter board became defective but it could also be that the power supply does not provide the +24VDC to the back light inverter board.
If you could do the +24VDC test using a voltmeter then we can say for sure that the back light inverter board is defective.
Let me know if you need further assistance.
