All in one v2.8 kit help

1.Measure voltage on pin 32 of Atmega.

Disconnect from USB/power down MegaDrum.
2.Measure resistance between pin 32 and pin 11 of Atmega in both directions.
3.Measure resistance between pin 32 and pin 10 of Atmega in both directions.

pin 32 is 2.5 V
resistance 32 to 11 is 4k6
resistance 32 to 10 is 4k6

Anyway it seems that I now have even more trouble. As I was pulling the USB cable out it seemed as though there was a bad connection there and now the Atmega is completely dead. The board still registers fine with windows, but onboard LED is off, and LCD is showing nothing.
Man this was not supposed to happen. Now I wil have to buy a new Atmega32.
How do I make sure that I wont burn the new one as well?
I am getting desperate here.
I even considered to buy an Alesis Trigger IO for a short while.

It's correct if you measured it on a pin of Atmega IC itself, not on the socket or under the socket.

Is Atmega properly seated in the socket?
Power it up with the key LEFT pressed. Don't press any other keys after that! Can you see anything on the LCD? Even if you look at it at extreme angle?

Don't blame your Atmega yet. It should not fail just because you pulled the USB cable.
I got tired today and it is now way past my bed time. I hope I'll be able to help you tomorrow.

and be careful of static electricity !!!

Trying to get it into firmware update mode with the LEFT key pressed does not change anything. Cannot see anything at all.
How do I confirm if the Atmega is alive or not?

Witch of the programmers by dmitri should i use for the atmega32 bootloader programming? The ISP or ICSP?

Ahhh S***. I have neither a parallel or serial port on any of my computers.

I am asking because on the synthex v2.8 board it reads ICSP for the Atmega. I believe I have read in other threads that it should be ISP, or maby it does not matter.

The reason that I think the Atmega might be dead is taht I behaved very badly this night. In my frustrations I think I did some soldering with the IC in the socket. Plus I may have fumbeled around with the board without caring for statics a little to mutch. Once AGAIN I have learned not to try and solve these kind of problems in the middle of the night. Will I ever learn?
