[Tutorial] How to Fix your Pico's Headphone Socket
Getting audio cuts, left or right channel always disconnects, audio distortion, or headphones not working at all? Well your Pico's headphone socket is loose. Solders on the headphone socket are somehow, cracked or just got detached from the board. Here's how to fix it...
DISCLAIMER: I AM NOT RESPONSIBLE IF THIS TUTORIAL BROKE YOUR PICO. THIS WILL ALSO VOID YOUR WARRANTY. PROCEED AT YOUR OWN RISK
Ok let's get started. Here's what you need:
- Pico ( of course :P )
- Torx and Philips screwdriver
- Soldering Iron
- Soldering lead
Step 1: Remove all the screws on the case using a small torx screwdriver and remove the case
Step 2: Remove the screws on the board using philips screwdriver
Be sure to keep the screws in a safe place
Step 3: Remove those black tapes. Also keep them in a safe place...
Step 4: Disconnect the Ribbon Cables...
Step 5: Take out the board CAREFULLY...
Step 6: Prepare your soldering iron and soldering lead
Step 7: Solder the contacts... ONLY solder the contacts pointed at the picture...
Don't apply too much solder! Solder it CAREFULLY! We don't want to short it...
I'm not really that good at soldering but that gets the job done
Now put your Pico back together and test it out. If this fixes your headphone connection problems, CONGRATULATIONS /) ! If not, try again
I would strongly advise you apply heat syncs when doing this, otherwise you can end up frying components near the headphone socket (I've managed to do this before when using old solder that wouldn't melt easily)
Another tip, use the smallest tip you can find for the soldering iron. if all you have is a chisel tip, don't use it. it's too much risk!
lastly, make sure you clean up the old solder. don't mix new + old
I also recommend looking at some soldering guides. it's easy to do a bad solder and make stuff even worse.
