REPAIR: IDX JL-2+ fan

We all have one. Those pricy blue little bastards that keep our rigs running for hours upon hours. The IDX JL-2+ lithium NP charger. They rarely seem to completely fail, but most common issue I seem to have, as well as most other mixers I've talked to, is that damn fan the keeps drives the heat out of the unit. My units travel a lot and the baggage handlers seem to toss them around like a burger at a tailgate despite that fact that the case has a sticker asking them not to. Shrug. Anywho, between the 10+ units I have 90% of them have had this Loose Fan Syndrome (LFS) at some point in their life. When you hear the charger kick on and it sounds like it's about to come to a screeching halt, your JL-2+ has LFS. My most recent victim was much worse that the others...it had come completely apart and was jumping around like a 5 year old in a bounce house. So I decided to share my DIY repair job. Read repair, not reinforce. Grab your Lectro tweaker and let's get to work!

NOTE: This may negatively impact any warranty provided by IDX on your unit. I am not an authorized technician. I'm a sound mixer that doesn't want to send my gear in for a repair I could do myself. Performing this repair is at your sole discretion and risk. Please think before you do this. I'll ask them for any specifics, but please repair at your own risk.

Step 1: Remove the padded feet

Pull off the foam rubber padded feet from the bottom of the unit. They're on there with a glue of some sort. Simply pry them off with your tweaker. Set aside.
 Step 2: Unscrew the plastic frame

The screws have a Phillips head––which by the way was first used in automobile manufacturing––but I found that the flat side of the Lectro tweaker was long enough and still fit the Phillips head. You can't use the Phillips side because it's too short. Unscrew all four corners and set the screws aside.







Step 3: Remove plastic case

The top will pull off gently once unscrewed, leaving a bundle of cables still tethered. Let them be. No need to desolder or disconnect.


Step 4: Diagnose severity of the damage

Like I mentioned earlier, the fan on my unit was completely dislodged. I've had issues in the past where a good tap with your hand a few times will bump it right back into place, so don't do all this if you don't have to. The fan itself is attached with a magnet, so it can easily become loose if it's knocked around too much.










Step 5: Move fan blade back into place

Here you can see the other side of the fan base. The magnetic fan blade simply reattaches to this base. 








This is the important side of the fan blade. I personally think it's kinda nuts that the fan blade has a circuit board on it, but I'm sure those folks over at IDX have a reason.




You can use the Lectro tweaker to help you "lock" it back into place. You'll be able to feel when it's right. You can even plug it in and put a battery on charge to test it.

Step 6: Reassemble
Once your fan is reconnected, pop the lid back on, turn it over, screw the screws back in and reapply the foam rubber feet. BAM! You're right back to work.
