Edifier c3 over voltage input

[8imra]

Hi guys newbie here, I do have a edifier c3 but it was accidentally plugged into 220v instead to its 110v rating voltage.
I was able to replace the transformer and made it come to life, though the amplified output still failed to fix, as my observation the amplifier section (circuit board) is separated to the main pannel located in front, in which the front pannel is working fine, headset plug is working, volume control and all the buttons and the only defective is the amplified setting.
Any ideas are highly appreciated..
Thanks and have a nice day..

Hi, I am also a user of C3 edifier,
Maybe we can help each other.

My problem is the zener diode,
Unintentionally depressed, and broken.

Can you help me ?
To see on your board, with PCB code "D105"
On the main board, there is only 1 zener diode
What type of zener diode is it?

To be safe, you should remove from PCB,
Because the place is narrow,
Unless you can read it clearly.
Because of the writing on the diode, circular around the diode.
