Hi Craig. Thanks for another interesting video. Question for you - how do you know the LEDs are 3v each? Also I'd love to see a video of soldering work done on those LED ribbons - I had a similar issue a while back but didn't brave it for fear of destroying the ribbon.
Hi Matt, Good questions. 1. The LED voltage, I look for what voltage rating the power supply is outputting to the back light. I also look at how many LED's are in series. Divide the voltage by the number of LED's in series - you get an approximate LED voltage. Sometimes, if you look carefully - the LED strip will have a voltage rating, divide this by the number of LED's on the strip. The biggest headache is to get the right package LED, with the right current rating and the right color range. 2. I will do this with the next one I get it. I will also take you through the whole disassembly. The de-soldering and re-soldering is very simple. I use my Quick hot air station with the medium nozzle, highish air flow, and ~320°C. I just wave it in small circles under the strip under the LED I want to remove. You will see it come loose. I will also show this in the video. Many thanks for watching. Craig
Awesome Video Craig. Love the through explainations. Keep going please!!!!! All the best to you!!!!!
Ta Andre,
Much appreciated.
A lot of the boards that I'm looking at now are being sent in by viewers - which helps.
Cheers
