Replacing LEDS on Keyboard... how to?

This is more of a general question. How do you remove LED's from a board where they've been solderd on? I have a Logitech Elite keyboard and I'm trying to replace the LED's in them. I've opened it all up and got to the mainboard. Here's what it looks like:

Here's the front of the main board with the green LED's on the lower right.

Front of the board again, sorry about it being blurry.

Here's the back. On the lower left are the metal holes/tabs/soder crap.

Closer image of it, but I know it's blurry. Sorry again. Trying to do my best here to show ya guys.

Here's my soldering iron.

My prime question is, how do I remove the LED with the solder gun? Do I need a different tip? Can I use the tip I have? What happens if the solder stretches and touches one another, can I leave it like that? I don't think I'm suppose to.

So whats the best way to go about doing this? And putting one in shouldn't be to hard, right? Any tips on this?

Thanks fellas,

if theres solder thats touching another contact than the one you intended it to i wouldnt feel comfortable powering the sucker up. a google search would be fine to help you understand. i have seen lots of these articles around the net.
 
It should be doable if you're soldering skills are good enough. I don't know how closely the leds are attached. Do they stand up a few mm? or more?

Also your closeup pics don't help at all, either you aren't in macro mode or your camera can't focus that close. I'd say don't bother with them.

If you've got a flatbed scanner you can try scanning an image of the part.
 
ITs not that hard if you have the soldering skills. I replaced the LEDs on my keyboard with Ultra Brite BLue LEDs. Farging beautiful!:)

I will see if I can find the link to the guide I used.
 
Hmmmm alright.

Yes, my camera is just old. I'm no fool about the cameras and macro mode. Thanks for the tip anyway.

i think ur biggest problem for that would be that the leds would be too far or too close to the board so when you put it together again, it'll seem like it sinks into the keyboard or pops out too much....measure the distance before you solder and make sure you have good soldering skills

i m planning on putting lights to shine over my keyboard and also something similar to what your doing to the circuit board... i want to take out the control panel in my subwoofer and change the crappy green led to a bright blue one
 
its actually very easy to do. i replaced the green leds with blue ones in my Internet Navigator Pro.

I used a cheapo £10 soldering kit. Heat the solder up, touch the solder on the back of the pcb, lift up the existing led. melt whatever remaining solder is on the pcb and clear it off with one of those solder clearing tools (lol sorry, dont know what its called, came in the kit). Drop the replacement led in (making sure the + and - terminals are in the right orientation - just match it to the old led). solder it around the back and once cooled snip off the legs. Repeat for the other three times.
