Nearly every time I modify a console, I like to change the Power LED (unless the mod includes a new power LED like the switchless mods), green or red are pretty boring, and a different coloured LED reminds me that the machine has been modified. When adding a modchip to a PSone recently I though it would look nicer with a white power LED.
This is a fiddly job, if you haven’t soldered SMD components before then definitely get something else to practice with first. Once you are confident that you can solder an SMD component without having to use a lot of solder, and being able to get a good solder joint by just touching the soldering iron quickly to the components then give it a go!
Taking apart the PSone is easy, 6 screws (one under the silver sticker), then 2 cables for the CD drive. Then you have access to the motherboard. The power LED is quite big for an SMD LED, and I can’t remove it using my normal SMD removal method (see the 360 LED guide), so instead, I take a pair of side cutters and snip as much of the LED off as possible.
Depending on how much of the existing LED you manage to snip off, you may have just the contacts of the old LED to heat up and flick off (first photo below), or the whole base left to remove (second photo), if it’s the whole base, ten simply add some solder both sides of the LED base, lie your soldering iron down so it touches both the + and – ends of the LED base and you’ll be able to flick it off with either the soldering iron or a little screwdriver.
You can see I’ve labelled the positives and negatives of both the console and the LED (SMD LEDs usually have a mark on their bottom similar to the one shown). I’ve seen two different motherboards for the PSone, both had the same polarity for the LED).
With a pair of tweezers, hold the LED in place so that it touches both bits of solder left behind from the last LED. Then quickly touch the solder and push it towards the contact point on that end of the LED. Take the tweezers away and lightly push the LED, if the solder has taken to it, then it won’t move :-)
Repeat for the other side of the LED (tweezers probably not needed this time), and you’re done! You can power it on without putting it back together to test it quickly.
I had a bunch of SMD LEDs hanging around from other mods I’ve done (360 and PS3 LED mods), they are 0203 SMD LEDs, a bit smaller than the original LED, but they still work fine.
