    • There are many models but few differences.

    • Most model changes had case differences but the only difference i saw in the components was whether the speakers were soldered in or plugged it and a small change in placement of capacitors.

    • Inspect your motherboard as much as you can before removing it. Get a game plan. The issue is generally obvious.

    • Most flip 3s suffer from one of these issues:

    • Its USB port was damaged by a drunkard who didn't care to check what way he was inserting the cable. It actually is delicate though so I shouldn't complain too much.

    • The battery has gone bad. Most of the time the battery expands and presses the case into the buttons making it turn on but be unable to turn off or use buttons. The best way to check is to try to use the buttons. If any are not working it is a probable issue. Often the case becomes curved slightly.

    • It was dropped. Often an inductor breaks off. Sometimes it doesn't break off all the way but you would need to solder it back on. Its actually quite easy. The sign that this happened is everything looks good but there is no sound.

    • The flip 3 charges but does not turn on. An expanding battery or a drop led to the small white ribbon getting ripped by the battery. This took me a while to diagnose as the ripped point was right on the exit hole to the control module under the motherboard.

    • I have seen various issues relating to forever charging, control issues, the flip 3 turns on but won't turn off. There is a little chip next to the battery connection and is almost always the culprit. Sometimes a trace is burned, sometimes everything looks good. I believe that chip deals with power on states.

    • USB: I suggest to replace the module instead of trying to replace the port. Its quite hard. Small pins delicate pads close plastic. Good luck.

    • Battery: Get a new one. Its not too hard to replace the battery. Just don't pull the connector. Use a flathead screwdriver to brace the plastic part the connector is connected to else it could come off the motherboard. You have to dig out glue to get the connector out but just go slow and avoid putting too much pressure on the cable.

    • Inductor: Solder on the component "1R5" its not hard if you use flux but don't hit the nearby pieces! I think I spent 30 seconds soldering this but 30 minutes getting to it!

    • Ribbon: Replace the ribbon. You have to remove the motherboard so most of the risk is getting to the ribbon. Sometimes the connectors have glue other times they don't. Spend the extra time thinking it through before you act!

    • Microcontroller: Kiss it goodbye. Im stockpiling these boards until I get a hot air station. If you can get that replaced with a soldering iron, your my hero! I do know there are people who can do it but I'd rather not wreck lots of them to know I need the right tool.

Work slowly and think it out. The chances of getting it fixed go up if you don't break it in the process of repairing it!

I have a flip 3 that will not put out sound. It worked twice after I bought it. Now I get no sound when turning it on or from my bluetooth device. When I turn it on I get a faint click sound, but nothing else.

I checked the indoor & it's not loose or damaged. I'm at a loss what the issue is.

Any ideas?

I'd put my money on a chip failure. I click to me suggests that it is preparing to work and is interrupted. If all the solder joints are good and no damage is seen then an inline capacitor tester is a good thing to check caps.

We really need a board diagram with voltage test points to properly diagnose these.

My flip3 fell on the floor once and the buttons and leds stopped working.

I found out that the ribbon was completed severed. So weird. No idea how it could have happened.

Where can I find a new ribbon? Looks pretty special at about 240mm long with 13pins.

I have a few.

EBay is a good resource. Flip 3s are a commonly repaired item.

I dipped my flip 3 into a tub for few minutes it worked well for few days but after few days it started to malfunctioning it turns on and of by itself the Bluetooth connection with my phone doesn't lasts for a minutes so please help me

I’d put money on corrosion. There is likely oxidation that is short circuiting pins/traces. This corrosion could be anywhere and everywhere…. Even apart of the battery. I’d clean up everything with alcohol and q-tips.

Tyler Freeman -

I believe some kind of sand or water got into the USB port of my flip 3 and for a while I had to prop up the speaker perfectly with the charger insert placed perfectly and it’d charge but now as of today no matter how I move it around in the USB port my charger will show no signs of charging m. If I turn it on and it makes Bluetooth connection with my phone it turns off instantely due to low battery! please suggest what I should do!

Replace USB module. You might be able to realign the USB pins but generally it will fail again.

Tyler Freeman -

Looks like the USB port or charger is damaged. Prolly the port from your description. It also could be the internal connections of the port.

Replace the module. I have a few left.

My grandson was trying to help me by plugging the USB cord into the port on the speaker. I'm almost certain he bent the thin metal price inside the port. Please help save this as it also has sentimental value! My grandson cut his teeth on it & he's a very special Angel born at just 26weeks gestation to a very scared 17hr old soon to be mom. Being born so early & having to fight to beat all the odds of surviving. He's now a PERFECT almost (Nov 17) 3yr old healthy, energetic,exceptionally smart & handsome little man!! Thank you

Se me ha caido y no suena. Las luces andan. ¿Cual es el problema?

Agustin - Ответить

Puede ser un inductor o una cinta rasgada.

My 2,5 yrs Flip 3 being charged has constantly after about 5 minutes a spontaneously shutdown. Is this a signal that the battery needs to be replaced? in that case I could spend 15 Euro. thanks for advise, if possible.

lucky - Ответить

I’d put money that the battery is getting warm expanding ever so slightly and forcing the case into the power button.

If this happens:

1-Can you turn it back on immediately or does the button seem different? Check all buttons.

Yes: It might be chip/SMD issues.

No: Battery.

Every time there is an issue, I inspect, fiddle and observe. Since there is a commonality of battery expanding in the unit and mushing the buttons from the inside, I’d assume that yours is at the level where it is beginning. Most of those I mess with have badly expanded batteries. So I haven’t seen it begin.

Hi Tyler and all,

The first of the five led (for charge indicator) is blinking forever when I try to charge my flip. It turns on (without any sound) and can connect to BT but that’s all.

I changed the battery but that’s not the culprit.

I removed the motherboard but I don’t know what to begin with. Any idea?

cottet cyril - Ответить

I am at the exact same spot. Did you ever solve this?

Niclas -

I have the JBL flip 3, I just replaced the battery and everything works, I get some rattling every now and again, its not consistent but persistent enough to be a nuisance. any ideas on what it could be? Im guessing its related to the battery being replaced? It doesnt do the crackling like when the battery was going out but its more of a rattle now.

socomfort2 - Ответить

I have two Flip 3s. The first one keeps turning itself on and off at random. The power on button is also not very easy to press. Suspect it’s a battery issue.

The second one crackles and makes a cracking and buzzing noise when turned on.

Any thoughts on how to fix them.

Laura - Ответить

Hi, my trusty old Flip 3 makes a cracking noise when you increase the volume. Any idea what is causing that and if its fixable?

i have a jbl flip 3 se i tried holding in the music pause botton and the volume up botton to hard reset it but now it wont turn on at all. if i plug it in it turns on but bluetooth doesnt turn on and it turns off right away if i unplug it

what do i do?

Marcus Bjerning - Ответить

My flip three is scratchy at medium to high volume what should I do can you give me a price ?

Diego Morales - Ответить

Same here, anything above 20% volume max scratching noises as if the Bluetooth starts glitching up. But I’m pretty sure it’s not the Bluetooth connection that’s the problem, I’m more thinking towards broken amplifier?
