Tektronix MDO3014 failure, MDO3000 series
<< < (5/9) > >>

I have a 5 year old MDO3000 too. It has had very little usage, and in recent weeks I have noticed it resetting. In my case I have only seen this happen during startup. The display is blank when normally the splash screen should be displayed, and it power-cycles, and this happens several times until it manages to fully start up, and it then reports no errors.
There was an older firmware release note that discusses a fix which restarts the MDO3000 if the display fails to start up, but I do not know if this is what is happening, or if the MDO3000 software would restart everything if the display does not respond after startup as well. This could all be unrelated and I may have jumped to the wrong conclusion.

It sounds similar to what was happening to mine, however I get the splash screen pretty much every time. Sometimes it just seems to hang there, sometimes it will go through the boot. It doesn't show that anything is wrong in the POST results. My issue got compounded when it did one of these resets during an update to the latest (1.30) firmware. That reset corrupted the code in the front panel microcontroller. Even with the latest firmware it still does the restarts.
m k:
Is it staying up in the cold?

How far back Tek is supporting?
Link seems to have MDO3000 Series_v1.10

Not sure what you mean by staying up in the cold? The most recent firmware is v1.30, which didn't fix the problem.
m k:
If you have a place where the machine can be in low ambient temperature maybe it is not resetting so eagerly.

Then if you downgrade far far away back maybe your corrupted part gets some new old code.
Assumpton there is that upgrade is upgrading only those parts that are included in that upgrade.

Are you back in square one but with new firmware?
