DS1054z No waveform on any channel

Hi all,
Been a reader of the forum for a long time.
First time I've needed to make a post, as usually I can find anything I need to know in the forum!
I am a beginner/hobbyist and have one of the ubiquitous Rigol DS1054z oscilloscopes.
Until now it has served me well.
On last usage and shutdown, everything had been working fine.
Upon next boot up (a few days later) I discovered that it was no longer displaying any waveform, of any kind.
Not even the usual "noise" etc, of just having a probe plugged in.
Absolutely nothing! There is no line of any kind across the screen.
This is the case on all channels.
I tried a good few power cycles.
I tried a reset by holding the 5th left side grey button in, during power up (resulting in changing to a Chinese language layout)
I've tried the simple "default" settings button.
There is no difference in having a probe connected, or not.
All buttons, settings, etc, appear to function normally, allowing access through the menus to make changes to settings, etc.
Trying different trigger modes, and "Auto" make no difference.
Does anyone have any idea what the problem might be!?
I was kind of hoping that it's just an easily solved "glitch" rather than having to go through the hassle of sending it back!
Thanks for any help!

Did you try doing the scope calibration routine (remove all probes first) Utility - Self-Cal. What happens?
-

So presumably the other screen displays are showing up correctly? Graticule, top bar, channel setting indicators, menus, etc all showing up properly, just no signal traces?
Run/Stop button green, scope is actually running (showing green "RUN" at top left next to "RIGOL"), and so on?
You have Utility>System>Power Set>Default set in the Utility menu?
I have not heard of this problem before.

seems ulikely it would die like that. Is it remembering the previous state/settings after a power cycle?
Try holding down this button when you power it on.
After that, do a calibration.

Xrunner - Yes, I have tried "Self Calibration"
It appears to run, but then just hangs with the first blue part of the progress bar stuck. (the blue section that pops up immediately)
alsetalokin4017 - Yes, that is correct.
Everything else appears to be "present and correct"!
Even the Menu/Settings appear to work.
Yes, it is set to Power - "Default"
Fungus - Yes, I have already tried that reset method (mentioned before). It appeared to actually "Do" the reset, as the language reverted to Chinese.
Unfortunately, it had no effect on the problem.

Well I don't know ...
Well what if you connected a DC power supply to channel 1 and say cranked it up from zero to say 30V, and then reversed polarity and did the same thing. Do you ever see the trace fly past on the display? I wonder if a big bias has been applied to a critical stage that is the failure that affects both ac and dc settings on all channels?
See what the other guys say ...

i have a bad feeling about this (i cannot get my trace disappear as in the picture)...

If a trace goes off the bottom it will disappear from the screen.

It's starting to sound like a genuine hardware fault. How old is it?

trace goes off the bottom (or top doesnt matter) when no input connected... i have a bad feeling about this...

correction... no! on ds1000z, if signal clipped to top or bottom, there still trace on top or bottom most (see attached, signal is dso's compensation square signal), so yes i still cannot get my trace disappear...

What happens if you press the Run/Stop button to stop the scope, then press the Clear button?
Or, in Normal trigger mode, set trigger level to something positive, so the scope enters Wait... then press Clear button?

Not much to add to what's been said.
As a last resort you might try to reflash the FW, in case it has been corrupted somehow.

I'ld also say, flash the firmware. Reset it to default (storage->default). Put scope in "single" shot mode and press "force trigger". Does the run/stop indicator turn red? Any trace of a trace
? If the indicator stays green, there's problem with the trigger engine. If it goes red and still nothing visible on the screen, your guess is as good as mine. Probably hardware fault. If it's out of warranty there would be little you can do. Maybe open it up and check the power rails around the ADC, the PLL and the FPGA.
Good luck!

A very long shot and no doubt you've already considered it... is there any chance the trace brightness has been turned all the way down?

Nope, that's the first thing I thought of too but my DS1054z still has a respectable trace brightness even when it's turned down as far as the control allows. Even tried Dots instead of Vectors, still shows a nicely visible line when brightness is turned down all the way. Grid brightness too, although that doesn't affect the trace brightness.
Also this is one of the parameters that gets reset to default (60 percent I believe) when doing the factory reset or startup>default on startup.

This ^, but the prospects probably aren't good.
If flashing the firmware (if it allows you to at all) doesn't work, then it's time to contact Rigol. I'd get in touch with Rigol before poking around in there, myself.

The defaults button should put some traces on the screen on any piece of test equipment. If that is not the case for the OP's DS1054Z then I think it is time to contact Rigol.

one doubt, using the oscilloscope, be it, rigol, siglent, hantek, on average one hour a day, always taking precaution not to demand it beyond its limits which is on average useful life, since I see people who have the rigol ds1054z since 2015 and it works perfect. Or it's like my grandmother said to the one who gets the black leg, who will hold on.
in spanish
una duda, usando el osciloscopio, sea, rigol, siglent, hantek, en promedio una hora por dia, siempre teniendo precausion de no exigirlo mas alla de sus limites cual es en promedio la vida util, ya que veo gente que tienen el rigol ds1054z desde el año 2015 y le funciona perfecto.O es como decia mi abuela al que le toca la pata negra, que se aguante.

It may not be related to the self cal, as I assume you were running it to correct this problem, but has it ever finished since? What happens if you shut the scope off before it finishes? It takes a long time to complete. How long did you wait when it seemed to hang?

Have you tried to save as csv or wfrm and check what you got?

Well, after being really disappointed at the sudden death of my oscilloscope, and getting nowhere with Rigol for weeks, I'm finally geared back up to have another look.
As to the last post...... It doesn't seem to want to let me write to the filesystem.
The buttons are grayed out (Save, etc) I will try it with a USB stick......
(I should be able to save to the internal storage though, shouldn't I ?
I've done a "factory reset" of software, via LAN.
I've done the "fifth key down" reset - back to Chinese language, etc.
So now I'm really hoping that some of you might like to throw in some ideas, or even test procedures I can follow.
As a re-cap, basically I am getting no traces at all on any of the four channels.
(see earlier pics)
I am just a beginner hobbyist and am out of my depth here!
But I am capable of carrying out tests and measurements!
Maybe someone has an open DS1054Z and could give me some measurements I could use as a comparison base?
What could possibly knock out all 4 inputs!??
I'd appreciate any help at all!
Thanks for any suggestions.

Have you tried to change memory depth, switch to hires mode, dots mode, XY-mode and still no visible trace what to ever? Have you turned on any measurements? Do they display plausible data? Does the hardware frequency counter still display the correct data when you feed in a signal?
