Repairs / Insides

This chapter covers the speakers hardware (models, repairs etc)

Jim:  There seem to be common issue when the boot loader fails and a reinstall of the firmware directly to the ARM processor is required. 

The WAM's are cleverly designed and put together like a puzzle and the WAM R series are even more difficult to disassemble than the WAM S series. I just recently opened one of each and they look like ARM processors so probably an Serial Peripheral Interface (SPI) programmer. I can see no contact points on the Printed Circuit Board (PCB) that is visible at the moment but will remove it soon to see if there are any on the bottom of the Printed Circuit Board (PCB).

see http://your_speaker_ip_address:8001 for hardware specs of your device.

You can use a simple tool on your mobile like fing network scanner to find your ip address. Fing is available for both Android and IOS.

Power Issue (no led)  with the M7

I have seen  several M7 speakers with a broken power supply. No led when you turn it on.
You can easily replace the power board unit by pulling off the bottom plate and unscrew all screws.

Inside the M7: 

Moosy: Sept 2019 - Two of my WAM751 / M7 speakers are defect. Both just broke down and down power up (no led or anything) short-circuiting I assume.

I opened one to see the inside:

You see the dark/black area on the second pic. Part number on the board: CN07AH4400307ASK28F464564

Moosy : June 2019 - Opened my M5 WAM551/XN to see if I could connect an external WiFi antenna.

The WIDT30Q does not have standard capabilities to connect an connector.
