Just before you ask, it is an auto-darkening one
Tecmen, ADF 7305. Hadn't been used in a couple of months, found to not be dimming at all, so I replaced the battery. Now it's dark all the time and won't go back to normal. Any ideas? What kills these things? I had a look at the circuit board but didn't see anything amis.
