How to Repair the Flashing Red Light of the Zeppelin


How to repair the flashing red light of the Zeppelin, which occurs when you plug a device in.


Relevant Parts

  • 2,220 uF 16V 105°C capacitor


Step 1

  1. Disassemble the Zeppelin, by first removing the soft rubber support (fixed by tape).
  2. Remove the 4 screws that are holding the silver ipod support. (You'll need a T20 bit with a hole in the center - available on the ifixit pro kit)
  3. Remove the ribbon cable from the base. (Be careful with the connector, it need to be slide very gently !)
  4. Remove the two black covers, by sliding them gently out while pressing the release "switch" located on the back part of the black cover.
  5. You'll find 8 phillips screws, holding the speaker assembly to the silver back of the zeppelin. Carefully unscrew them, but be careful not to detach the front from the back

Step 2

  1. Gently separate the back from the front.
  2. Remove the earth wire attached to the power supply, as well as the main connection (two wire cable attached on the lower part of the power supply).
  3. Remove the ribbon connection from the main board (be careful with the connector, that need to be released very gently)
  4. You may now check the power supply for inflated capacitors. It is very likely that the 2200uF 16V is the one.

Step 3

  1. Remove the power supply connection on the top of it
  2. Remove the 4 screws that are holding back the PSU from the back shell
  3. Remove the 4 screws that are holding the pcb from the aluminum base.
  4. Change the inflated capacitor
  5. Make sure the thermal paste is still present on the semiconductor on the base.
  6. Replace the PCB on the base, and the power supply inside.

Step 4

  1. Plug every wire back.
  2. Check if everything looks secure inside
  3. Place back the cover and the 8 philips screws.
  4. Gently slide the covers, by making sure they are aligned on both sides (there is some rails, and the cover has to be slide into). Make sure also that you are not mixing the two covers (there are not identical, the one with the rubber protection on the led output goes on the left).
  5. Assemble gently the ribbon for the ipod dock.
  6. Fix it back with the 4 screws.
  7. Put back the rubber part.
  8. You should be ready to go !

Isaac - was there any difficulty in replacing the entire PSU?

Hi Isaac, is the power supply module a direct swap for the output connector do you need to change cables and pinouts? Kindly email me details if possible. poopoobud@gmail.com thank you.

Hi, just replaced the PSU but the light turns white and nothing happens??!

Any suggestions?

best regards

Hi Rune,

I didn't replace the PSU but I am stuck as well with the white light - meaning firmware update mode - but the firmware does not update even though the Utility App seems to work fine.

Have you got any luck ever since ?

Thanks in advance
