Wifi Camera stop working

[sdancer75]

Hi,

I used for about 1.5 year a Security Robotic Eye camera from  https://cvmore.com/en/smart-security/. It seems that it has the same board you can find in DOG-1W-V5 from Shenzhen CYLAN Technology https://fccid.io/2ADHE-DOG-1W-V5/Internal-Photos/Internal-Photos-4017528.

The camera is not working and it seems that the board problem, it burned also the USB charger.

I noticed that the speaker is getting too hot as well as the IC8310 which at the 1st glance searching on the internet is a "16 steady-state current LED driver" but its probably wrong since the output of the speaker is getting out from this IC. So I think its an older model of ES8311 IC which is a Low Power Mono Audio CODEC (I suppose they are compatible)

https://pdf1.alldatasheet.com/datasheet-pdf/view/1132836/EVEREST/ES8311.html.

Due to the small package size (QFP) I can not test the input analog and digital  voltages pins (DVDD, PVDD and AVDD). How to handle this situation?

Regards,

Everest Semiconductors provided me the original datasheet of the ES8310 IC. Because I didn't find anyway in the web, I attach it here for anyone that is interesting about.
