Quoted from shlockdoc:Turned on my TZ with original clock board and got the “clock broken” and the hands do not move at all either at startup or in test. Is this motor related or board related? Where do start to diagnose? Thanks.
Check the wires at the molex plug on the clock itself.
I have seen 2 clocks not work just because of an internal wire break at the bend in the wires right before the plug.
Hope it's any easy fix. But that is the easiest place to start diagnostics.
