Rigol red screen of death
SkyMaster:
There is also the yellow screen of death
and the snowy screen of death
This was a brand new (a couple weeks old) DS1054Z that would randomly crash like this. Sometimes the screen was dark. Sometimes the screen was still being updated. But in all cases the controls became unresponsive.
Typically, before this, the hardware frequency counter would stop updating; the last read value would remain latched. Then it was just a question of time before the oscilloscope became unusable.
This particular unit was replace under warranty.

Having repaired a Tek 465 and a Dumont 1060 the thing that struck me was how easy it was to sort out the circuitry when it's all on a single board. It's much harder with multiple boards stacked on top of each other. In fact, it seems to me that you could probably extract a schematic using photographs and a bit of AI. An emitter follower shouldn't be that hard to recognize.
It may not be repairable economically, but there is certainly nothing to be lost if you are cautious. Of course, you *will* need another scope if it's anything more difficult than the PSU. I'd buy a new scope and treat this one as a repair project when I felt like messing with it. Or sell it to DC1MC who is looking for a dead unit for parts.

I'm afraid that my unit is ready for scrapyard or for DC1MC (that is forum member or what?). I tried with firmware update, but it doesn't work, or I don't understand procedure that is rather simple: copy firmware on the USB stick formatted as FAT32 and reboot the unit. Nothing happened.

Great, so over time we can expect a full rainbow :-//.

maybe you can sell it on eBay

What aspects of the engineering are you „looking at“ to reach that conclusion?
