I have fried my gc100-6.
I got one with a USA adapter, not an EU adapter.
So after long searching for a compatible EU adapter (consulted the printings on the plug and manuals).......it blinked for 5 seconds, and it went off.
Bought via via a US to Europe converter which are rare in Europe, and used the original plug, it doesn't work.
What would likely be fried, and is it easy to replace.
If you want I can make a pic of the board lay-out.
