Rigol red screen of death
prasimix:
So, after couple of years in almost daily usage, today shortly after I made some measurements on next power up I got this:
... after few moments red screen disappear but scope is not responsive to touching of any control:
Nothing was connected on it when powered on, and only "strange" thing was two short AC mains blackout this morning. I presume that I have to contact Rigol service.
prasimix:
I forgot to mention that few days ago on power up it simply change everything to default and set Chinese as user language. Don't know if that two incidents are related or not. Is it possible that flash is "flashed" and that some firmware part just gone? Anyone know of possible cure or "magic" selection of buttons during or after power up that could change current state?

Have you tried the 5th button reset? If this works it will also reset language to Chinese but should restore functioning... maybe.
prasimix:
Doesn't work, but I can hear beep-beep-beep tone that gone when display color is changed to red. It seems that some "intelligence" is still there, maybe some of power signals is missing (i.e. something is happened with power supply stage).
alsetalokin4017:
Had a quick look around Google and I can't find any other references to this problem.
Power supply voltages should be easy to check but beyond that, I have no idea what to suggest, other than contacting Rigol for service.
