I have been having trouble with my arduino ethernet shield i got from adafruit. When I plugged in the power, the LED power light goes on at about 1/2 brightness and then dims off. The chip that says 509Z gets also extremly hot and I was told when I posted this question to the arduino forums at http://arduino.cc/forum/index.php/topic,85931.0.html that this chip was a fuse that got hot and blocked current from flowing. I followed the instructions given to me on the arduino forums but it did not help as i can see no visible damage to either boards.
Any help would be greatly appreciated!

Re: Arduino Uno + ethernet shield Power Problems
Can you post some clear photos of the board? It seems strange that it would work for a while and then develop signs of a short.

Re: Arduino Uno + ethernet shield Power Problems
No obvious shorts on either board. Does the 509Z chip on the UNO only get warm when the Ethernet shield is attached?

Re: Arduino Uno + ethernet shield Power Problems
Yes, it does not get warm without the shield attached. Thanks for all your help.

Re: Arduino Uno + ethernet shield Power Problems
I do see some stray solder spatters on the underside. I suppose one of them could have migrated to somewhere where it caused a short. Contact [email protected] for a replacement and include a link to this thread.
