Toshiba 46RV5354 replacement lcd screen

Hi Erika,

If your LCD is cracked, you will need to unfortunately replace the entire LCD. Simply putting a screen protector (which is just a thin film) will not stop the crack from getting worse. There is unfortunately no magical way to fix your screen other than simply replacing the LCD panel itself, which is totally doable. Many electronics repair shops can fix your TV pretty easily. In some cases, you can even mail it into Toshiba.

The Toshiba Satellite M305-S4907 Notebook PC, uses a single CCFL for a Backlight.

Primer before we go on;

An LCD screen cannot produce light. It needs an additional light source,

Click on the monitor image.

The additional light source is a Backlight.
A Backlight can be a CCFL, (Or two of them), or a series of LED's.
(Light Emitting Diode)

A CCFL is a Cold Cathode Fluorescent Lamp.
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.

Average thickness is 2mm. That is a little larger than 1/16th of an Inch.
Average length is almost as long, as the LCD screen is in height.

A screen Inverter is used on laptops that use CCFL for Backlighting.
A screen Inverter converts the power (Electricity), from the laptop, for the LCD screen, and Backlight.

Laptops that use a series of LED's for backlighting, do Not use a screen Inverter.

90 PERCENT OF THE TIME the fault can be attributed to a bad screen Inverter.

The plastic thin frame in front of the LCD screen, is the Display Bezel. (Toshiba = LCD Bezel)
The screen Inverter is located behind the Display Bezel, and mounted at the bottom of the LCD screen.

Easy to get to; easy to replace.

How to test a screen Inverter? Requires a Sensitive multimeter.
Read fairly expensive,

http://www.fonerbooks.com/test.htm

Because of this; and the low cost, plus ease of replacing; most home users just opt to replace it.

Know this;
Fluorescent lamps have MERCURY inside. HIGHLY poisonous.
Now couple that with the long thin makeup of the CCFL, and how easy it is to break it.

This is why if the screen Inverter is found to NOT be the problem; I would suggest replacing the LCD screen itself; instead of trying to replace the CCFL, and cause possible Mercury poisoning.

Hello

First of all, I assume that your new LCD screen is compatible with theold one. Different screens require different video cables. Make sureyou new screen is compatible with your laptop.

Yes, it can be replaced but will most likely cost more than the computer is worth at todays prices. If it where me I would remove the screen and buy an LCD Flat screen and use the computer as a desk top if I really needed to keep it. Or remove the hard drive and put it in a mobile case and use as a back up drive and buy a new laptop.

LCD screens do not work the same as CRT tvs no vertical output IC, you have a screen fault which would need the screen replacing
