I had a thunderbolt that displayed a temperature reading of -54.99°C, which
I was pretty sure wasn't correct. ;-) Apparently the reference in the DS1620
chip either shorted or opened so this "D" revision chip was outputting its
lowest possible reading. I replaced it with a "C" revision chip th

It sounds like you have a Tbolt with the newer rev E (or greater) temp sensor
chip... which is not totally compatible with the tbolt firmware. Dallas

high resolution temperature readings.
Hello Maury,
A Lady Heather screen grab would be helpful in understanding the issue.
How is the power supply doing ?
I once had a flakey power supply that gave me abnormal readings.

display will come up
