If you didn't catch the previous post about how to successfully test your laser the following link to discover how to TEST YOUR LASER :)
What you will need:
- Low wattage soldering iron (20 -30w)
- No clean Liquid Flux
- Cotton bud
- Your faulty KES 400A (single lens)
Take your KES 400A and locate the diode, if you are unsure how to locate the diode then see the image below, although i recommend you view my previous post first. Also allow your soldering iron to warm up with a flat or square soldering tip, the tip should be small enough for you to work on each joint easily.
Open up your Liquid flux and dip the cotton bud, shake of any excess drips to avoid creating a mess.
Coat the diode anodes at the solder points with the liquid flux, you should see five of the solder joints all pretty close together.
Once your soldering iron has heated up, with a fine tip or square soldering tip you need to touch each anode joint until the solder re-flows (liquefies and re-hardens). You will need to do this for all 5 solder points.
Once you have successfully re-flowed the 5 joints you need to insert the laser back into your blu-ray drive for testing.
Switch on the console and try loading a game or blu-ray movie, hopefully you should be successful and be able to play you beloved PS3 again.
