I'm a fix it kind of guy and a friend of mine has two of the Weaver NightView #849397 Monocular that don't work. Right away I can tell that the power button is melted. I bypassed the main on/off power switch and it did not turn on and it drained the batterys. So my question is, do you know how to stop or fix the short and make it work normally?
