Hi there - Had my GMC-200 for a while and noticed that the LED was going crazy one night. Replaced the battery and everything seemed ok for 1 day. Back to going crazy with the LED (Mayan apocalypse? :-)) Anyway I can see a little tiny particle loose in the tube - do you think this could be causing the false alarms?
If so, which tube is recommended as the best/easiest to replace it with?
thanks in advance!

Then you can purchase a M4011 tube install yourself.
But you need to make sure it is the tube problem:
use a metal screw driver to touch the tube positive, the unit should have "click" sound. Also, check the voltage on tube, and make sure the voltage on tube is correct. |

i purchased it on 09/12/11 so I am guessing I am well outside warranty |

hi zlm, yeah mine seems to be soldered. It looks like a screw-bulb. |

Check your tube voltage, if it is shifted, then turn it lower. If your have 11M ohm multi meter, then the correct voltage should be about 170~180V on a 1000V range of meter. If it still does not fix the problem, then you need change the tube. Change the tube does not need soldering. It has clips and ties.

I should mention my soldering skills are pretty (cough)... BASIC! |
