[ICOM] IC-756PRO - Thumping, flickering screen, reset

[Lawrence Young]

David: The sympton could be caused by RF getting back into the rig somehow, or power supply limiting. More tests need to be run to better determine the cause. Is all OK when operating the rig into a dummy load? What is the measured voltage at the power connector at the back of the rig when this happens? Hope this helps.
