I thought this was going to be a comb filter but this one doesn't have it. I heated I501 which is listed as an ANALOG MONOLITHIC IC (YAT016H) and it gets bright. I then tried cooling it back down but stays the same. I can reboot the power then it goes dark. I'm not sure this is it. Anyone seen this?
