Vid showing me desolder one

 

Cut them first.

That will work for salvaging LEDs, it will not work for removing the failed ones to install replacements. That is the hard part.

Hi
Why not ?.

Perhaps the failed ones could be gently ground off using a Dremel tool with an abrasive cutting disc, then each half of the remains removed with the soldering iron. Or, since I happen to have a small electric hotplate (just big enough to make coffee) (and an infrared thermometer), I've speculated that it could be set to the correct temperature to heat those LED strips from the back side. I'd have to hold the strip down flat on the hotplate with something other than a finger and grab the LED with tweezers or pliers. This discussion at Sparkfun suggests that just might work:

Judiciously applied this stuff does an amazingly good job and might just help in this case.

Hi
Thanks for your reply I have all ready removed them with the hot plate , as per attached video, I will just do the reverse to solder the new ones back on, is there a problem with doing that ?
