DMD damaged after connecting with adapter

Post by statbat » Tue Jan 05, 2016 11:07 am


I first time connected my DMD with the power adopter. 5V and 4AMP adopter.
I am running arduino on 5 x AA batteries and DMD with the 5V adopter.

After running it on this 5V 4A for 5 min i noticed that one of the LED stopped lightening.
I checked the back and saw this soldering spread every where as shown in attached photo. Is it normal ?
The back of LED which is not working
The adopter is connected to the wall socket so I am sure it is properly ground in the home wiring.

Please advise. Thanks
