A friend of mine got two brand new AI Sol about two years ago. Yesterday he called me and said that the lights won't turn on and that he thinks that it is the power cord. I guess he hooked up a power cord from a computer or something and they came on just not very bright so he thinks it is from the power cord. I told him to contact the MFG and the wed site he got them from even thought the warranty is up. Dose anyone have advice or has this happen to any of you?
