THD & N Left Channel pretty sick left channel 9% THD at 10HZ????

THD & N right Channel.....I don't get it, worst I've seen on the left, best I've seen on the right...

Residual Noise left and right channels. They correlate to the THD & N readings..

Doing the board to board wiring tonight. Camera is on the fritz, it is possessed. During charging it turns on opens up, then closes. 3 minutes later it does the same. This has been going on for 2 days. Still doesn't have enough charge to get a picture....
