TDS3014 - screen freezes on startup
« on: April 28, 2021, 01:18:24 pm »
Hi Everybody,

I have an old TDS3014 that has just broken down in 2021! TDS no longer starts completely and stops at the logo screen.
I suspect the RTC chip DS1742 who include lithium battery for operate about 10 years.
See the attached file for more details  for the battery replacement in the DS1742 chip.

Thank
Eric

I also unsoldered the chip on my TL5204B and secured it with the data I / O. Then I soldered in a socket and now change the circuit every few years and secure the content beforehand. Works wonderfully!

A dead DS1742 does not normally prevent the scope from booting, it only makes the clock stop keeping time and stored settings are lost. Try holding down B-trig while turning the power on, that should clear and initialize the NVRAM in case it is corrupted in a way that somehow prevents booting.
