But I don't know if a firmware restoration could be possible without beeing detected.
1. After hacking the device, the warranty is void.
2. After opening the device, the warranty is void.
3. After modifying the device, the warranty is void.
I've done all 3.
Lot's of people have only done the first one.
(Using a non-Rigol MSO5000 Logic Analyser Probe will void the warranty ? https://www.eevblog.com/forum/testgear/rpl1116-active-logic-probe-pod-for-1000z-series-teardown/ )
In case of warranty needs :
I could totaly restore the device hardware without beeing detected.
But I don't know if a firmware restoration could be possible without beeing detected.
My goal is to provide a better longevity to this device.
The low quality power supply capacitors and all temperatures too high weak the device and reduce its life.

Hm-Hm...

Connecting a scope to the internet is a fantastically stupid idea, given that these products are not built by people with any real software experience.
Connecting a scope to the internet is a fantastically stupid idea, given that these products are not built by people with any real software experience. Just d/l the firmware and flash upgrade via a USB stick. I wouldn't be surprised if someone found a RCE vuln that could literally destroy the scope by messing with HW params set in software.
FYI: Magnuson-Moss in the US prevents 1,2,3 from being used against you unless Rigol can prove your mods caused the issue.
Not that Rigol is whom you should go with for warranty support or support in general, but the law is on the consumer side here.
Could you take a photo from the lcd-display, the backside ?
68°C on those poor devices?!?

Nothing uncommon for voltage regulators without explicit heatsinks.
The temperature is terrible if the part is rated for commercial use at 70°C - something hard to see from the then published photo.
Voltage regulators don't carry "explicit heatsinks" but properly sized PCB ground planes soldered to their Thermal pads instead.
P.S. The part is a TPS7A33, which is rated for 125°C, so it is ok for the part itself, but still not great for the overall system due to the temperature differences caused between the channels. But I grant this is par for the course of such integrated device.

Where these measurements done using black non-reflective spots (black paper stickers for example)? Otherwise the temperatures will be way off due to reflections and different emissivities.
The Rigol cooling system just stirs up the air.
I´m thinking about a "classical" measurement with K-Type sensors but at home I couldn´t measure more than 2 points at the same time.
At work we got a yokogawa 16-channel device..
By the way, my question about the decreased fan power and if they (rigol) got it in mind what heating up the enviroment concerns due to this wouldn´t be answered until now, very uncommon.QuoteThe Rigol cooling system just stirs up the air.
Yepp, today I got mine opening too to look what they´ve changed :
internal regulator 68C / 50C / 51C
hottest analog front-end channel 51C / 40C / 42C
LA connector 56C / 34C / 41C
hottest BNC connector 39C / 34C / 37C
