    You can replace the LCD inverter with a new one. Depending on your laptop model, they are usually fairly inexpensive...< $30. What is the model of your laptop?

An LCD screen does not produce light,

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.

(Do they break easily when trying to remove, and replace?

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.

Where to buy second hand lcd laptop for samsung sens 855

The best chance you have is to get your panel specifications and find a site where you can order the same panel. It isn't a simple unplug-replace-done process. It can be quite meddlesome. It would be much simpler to go to a repair shop where they have panels present for replacement.

Samsung Laptop SENS R46

Dear jungk1990,

I hear you screaaming for help, so here is the way...

Try to write down you Power Resource on down side of your laptop (You Must Turn IT UPSIDE Down To see it Clearly!!).

i.e : AC Input 100-220V 50/60Hz DC Input 15V 4400mA (blah..blah..!!)

Write it ACCURATELY (I mean the DC Voltage And the Ampere (mA) range..)

In the flash, visit (meaning: You drive you car or call a cab to drop eh.) the nearest computer Mall or Electronic center in your City, ASK FOR "UNIVERSAL LAPTOP CHARGER" !!

Match the voltage spec. with your note.. As far as the range is match, you can convince yourself to buy it, the UNIVERSAL LAPTOP CHARGER should come with several VARIOUS power jack that interchangeable to fit your inlet powerjack on your laptop. Better you bring your laptop and ask the Store-staff to help you out. That's it!

Good Luck,

look at the screen held in a bright light at an angle do you see the desktop dimly .
if not try the function monitor key,
connect an ext monitor to verify the video card is working ,fn monitor .
if you see the desktop dimly then the inverter may be out or the lamps.

This is very common with all makes of lcd tv unfortunately the transformers are near impossible to get hold of on there own.
Your best chance is either look on Ebay to see if anyone has A scrap complete tv same model for sale.
Or look for invereter board for sale.
Just to give you some idea of what you are looking for this is a link to A site in the UK that sells inverters.
