XE300 Puli doesn't boot anymore (after a fall!)

pvgonzalez · 2024-10-19T09:40:40.573Z

Hi,

I know this is a very long shot. A client returned a XE300 Puli that fell down from 3 meters, I opened the device and found a broken capacitor. As you can imagine, the device does nothing but turn some LEDs (PWR, WAN, LAN and 3G/4G) but it doesn't work

I would like to reuse this device for R&D and tests so, I replaced the broken capacitor but nothing changed. Even if I can't repair the device, now I'm curious about what could have happened to the device.

Do you have any leads that the problem could be ? (besides the device falling down, lol)

Cheers
Pablo Gonzalez

Maybe you can weld a serial port
See what happens when the router boots up

Do you have some update?

If the LEDs are always on when you plugin power, generally the circuit is damaged.

Hello, I lost hope. After plugging a serial port, nothing happens.
Either I didn't wire it correctly or the circuit is actually damaged.

I took the second hypothesis, so that it.

Thank you for all your replies.

Maybe you can post which capacitor is broken.
