I have a Senny G3 hh that wont power up. Pretty sure its not under warranty. It has minimal use but out of nowhere will not power on. Contacts all look good. If i re-seat the batteries a dozen times I can get it to light up. Low batt warning has flashed with brand new batts. Noticed if I leave batteries in for a minute they start to warm up. Thoughts?
