Sounds like an interconnecting wiring error. Check wiring connection i.e. wires are connected in right order 1 to1 2 to 2 etc. from indoor terminal board to outdoor terminal board. Also check for slack or loose connections.
Hope this helps I take the time to answer your question so please rate me

I'm having the same problem and can't find an answer. Seems this also happened with another model we had - planned obsolescence? It was working fine, flashing due to low battery. Now, nothing from outside. Annoying.

There is no way to turn off beeping. From this site: http://www.chaneyinstruments.com/FAQ.aspx
found solution - Q: My wireless weather station periodically beeps, why?
A: Make sure that any alert and/or alarm features are deactivated first. Constant, sporadic beeping is generally due to the unit's ability to detect a foreign radio frequency of another wireless unit when that unit transmits a signal. Wireless devices that may cause beeping but are not limited to these devices are; scanners; computers w/wireless keyboard/mouse; or other wireless weather instruments. Essentially, any wireless devices transmitting on a radio frequency have the potential to interfere with each other. Limit the amount of wireless devices to lesson the chance of interference. When beeping occurs, one device will need to be deactivated.

Another external temp gauge showed up on the other channel, so my neighbor or someone is using the similar unit. MY SOLUTION: opened back of case and cut black wire to piezo speaker (at base if rear cover opposite side of stand-up prop) that creates beep. ALL good now.
