have issues with my 2 tri gem leds

Hi tom. Welcome to the forums. I tried to get one of our service techs on this post but they were busy all day. You may just want to give us a call and we should be able to help you out over the phone.
You can call 1-800-322-6337 and ask for Tech Support and they will most definitely be happy to help you solve this issue. Thanks.
If you still have any questions let me know.
Sincerely,

Thanks! Tech support suggested I send them in but because I bought them used they are most likely not under warranty. I am semi savy with fixing electronics. With the issues I am having, does it sound like replacing the power supply could remedy my problems? And is the internal microphone part of the power supply? I could not find it in the list of replacement parts.

Those are really question you should have asked them when you had them on the phone. They would have been able to help you with those for sure.
Sincerely,

Since the unit is so inexspensive we normally will not order main boards for the units. It's cheaper purchasing a new unit if you need to purchase a board. The mic is located on the main board which we do not offer.
