I have just got a Leader LMV-186A where only channel 1 is working. Are anyone familiar with these? I also have a orange light on the power bulb, should probably be green light..? Channel 1 is working correctly, but there is no signal on the channel 2 meter. I cant even get the channel 2 meter-needle calibrated to zero.
I found a manual on line: https://www.leader.co.jp/uploads/2018/03/lmv186a_e.pdf
I have no familiarity but enjoy diy troubleshooting if you get stuck.
