Step 3: Remove the Backlight

 In this step you must be very gentle.  The lights contain mercury and are very fragile.  This step is not that difficult, just be patient.  Do not use any force when removing the CCFL or it will break (I speak from experience).  I would suggest that you loosen the wires from the LCD first and then gently remove the CCFL.

lol. &quot;CPU SPEED: FAST&quot;<br><br>a well written instructable, and we mustnt ever forget about the safe handling of ccfls, they contain mercury and if they break, you can get sick. you wont die, but you can get sick.
<p>I just did it - I found an old flat screen and tried the procedure. I took away all ccfl tubes from top and bottom, replacing them with Warm white LED strips (without silicon, as it will dry and get brown).There were 600 LEDs in 5meter log strip which I bought from eBay at approximately 10$. The power was taken from 12VDC line.</p>
<p>I replaced the CCFL bulb on my HP DV6-1030US 16&quot; screen laptop. I also replaced the inverter. The screen now turns on and lights up, but the brightness is not as bright as it should be. It is about 50% or less of it is supposed to be. I reset the PC by holding the power button for aprx 2 mins without power on or battery What could it be wrong? Please help</p>
What if u replace the CCFL with a Led strip? Could the led strip be connected directly to the 12vdc or 24vdc, skipping the inverter? Pls helpme.
Hey,<br><br>Yeah, you could definitely hook up an LED strip to do the backlighting....many TVs are doing that nowadays. <br><br>Can't give you a definite answer on connecting it to power however. I would imagine it would depend on what exactly you are using as far as the LEDs are concerned.... I'm sure if you look hard enough for a product online you could find something that would work
Nice instructable <br>Can you tell me where to get ccfl tubes from, as I have a use for them in a project I'm making.<br>Thanks
lol at the custom boot screen for win 3.1...
Is there any way to tell if its the inverter or the bulbs that are bad without having spares to swap?<br />
&nbsp;Hey,<br /> <br /> It can be a little more complicated with out spares, but usually it's more common for the inverter board fail first. &nbsp;It's annoying because both can have similar symptoms. &nbsp;<br /> <br /> If the LCD is on and running (still dark) but you can still see a faint image, then its either the inverter or bulb. &nbsp;If you can't see any faint image at all, or if weird things are going on in the screen (lines, craziness) then I would check to make sure all your connections are tight (especially on a laptop).<br /> <br /> <strong>However the symptoms listed below usually point to the bulb being the issue:</strong><br /> <br /> 1. The screen starts off working fine, but then it starts flickering and shuts off, but at the same time you see a faint image (shine a flashlight)<br /> <br /> 2. The screen lights up for a few seconds then shuts off (external output still works perfectly)<br /> <br /> 3. The screen works but has a red or pink hue to it (external output still works perfectly)<br /> <br /> I hope some of that helps! &nbsp;Don't hesitate to ask more questions!<br />
I've got an old 15&quot; in the junk pile someone gave me that only works if the inverter board is unplugged. I 'm pretty sure thats a sign that the inverter is bad but wondered if there was a way to test them.<br />
&nbsp;Ok yeah I agree, it does sound like an inverter problem. &nbsp;<br /> <br /> One option I would do if I was in your situation would be to just stop playing with the current bulb and inverter, and simply buy a new cold cathode bulb&nbsp;attached&nbsp;to its own&nbsp;independent&nbsp;inverter. &nbsp;Install this setup in your monitor and basically you would just flip the switch on the new inverter, and turn on your monitor and you would be all set.<br /> <br /> I just saw one the other day for $10....i'll send you the link when i find it!<br />
&nbsp;Ok I found what I was looking for. &nbsp;Check out this article and it will explain what I was talking about a little more clearly:<br /> <a href="http://inventgeek.com/Projects/BacklightFix/Page1.aspx" rel="nofollow">inventgeek.com/Projects/BacklightFix/Page1.aspx<br /> <br /> </a>Here's a couple sites you could check out for parts:<br /> <a href="http://www.xoxide.com/coldcathodes.html" rel="nofollow">www.xoxide.com/coldcathodes.html<br /> </a><br /> <a href="http://www.lcdparts.net/ccfl.aspx" rel="nofollow">www.lcdparts.net/ccfl.aspx<br /> <br /> </a><br /> Let me know how things go, I'd be interested to hear what you end up doing to fix it!<br /> <br />
