Hi everyone! I've been using a Mega 2560 for more then a year and it always worked. but now when I compile the blink example it returns this error: avrdude: stk500v2_ReceiveMessage(): timeout avrdude: stk500v2_ReceiveMessage(): timeout avrdude: stk500v2_ReceiveMessage(): timeout avrdude: stk500…

It's not that simple. The 16U2 is damaged; I don't know what other damage is done to the board. If the main processor is also damaged, you will definitely still have a problem. Do you have another Arduino? Note: There is a difference between compiling and uploading.

Trouble compiling with Mega 2560

That is indeed the 16U2 that I was talking about.

Please run the loopback test described in Loop-Back Test Instructions.

Disconnect everything.

Which servos?
Are they powered from the Arduino?
How is / was the Arduino powered?
