The EMI filter is built into the IEC connector but the fuse is separate.

It's the EMI filter built into the IEC connector. They do a lot of damage when they go.

I just love the look on the roo's face after the bloke clocks him one. All kind of "What? That's not supposed to happen! I, I, I,... [speechless]".

I'm not familiar with a schaffner filter. Here's the primary side of the Inverter circuit. Does it have one?
--- End quote ---
Yes, it does, better check the brand printed on it.
Its the grey metallic box under the yellowed white tube on the left side.
Also the plastic caps, as above photo those red boxes, if yours are transparent ones like below examples, replace them asap. Other wise they will pop too like these ...

--- Quote from: Specmaster on May 30, 2018, 12:27:02 pm ---Yes, its a jack of all trades but master of none as the saying goes, if they could fix the slight bugs and quirks it might be a really great purchase. I know Dave used to seriously recommend that model as a "no brainer" go get one but was 3 years ago.

All scopes are a jack of all trades though. They're mostly useless in the frequency domain, the time domain isn't all that accurate either and the voltage measurements aren't that good really. This is why we have DMMs, frequency counters etc as well.
However it's the only tool that does all of the above at the same time and draws them on a pretty picture and in this case allows it to hang around longer than the phosphor would :)
The bugs that remain for me in the Rigol are the shitty FFT implementation, some UI lag, naff probe coax and the DC drift that plagued my last unit resulting in a self cal needing to be done every week.
The big non bug is the price, crackability and the fact it has an ethernet hole in its bum.
Tradeoff really which it still wins pretty well. Keysight's offering I was looking at was about £1300. Versus £370 it's a no brainer. Siglent is pretty good there too (nod to tautech) but the distributors in UK are shit so you have to buy it from EU which has a worse statuatory warranty on it than if you buy it here in the UK

Which is precisely why I'm not ashamed to have one on the bench right under my 2465. I do a lot of work with SPI and I2C bus in my quadcopter hobby; this little beast was born for that kind of dirty work. :-+ The hackability was a selling point for me; the noisy power supply issues were something I thought I might address sometime to resolve the associated quirks, but as others have mentioned, the quirks of the UI are much more obtrusive in general. Once you get used to navigating it, the thing carries quite a lot of functionality for the price.
I spent quite some time carrying on a fun ethics argument over the whole Rigol hack thing in another thread; but eventually it turned into a telenovela with folks arguing the most idiotic semantic nits recursively for days. ::)

I have AC power in. The EMI filter is OK. No blown caps. But no mains AC to the primary rectifier bridge at the input of the DC bulk for the switcher. That's strange. Finally found the culprit. The power switch itself. It's a DPST switch and one side was open. So as a temporary measure I jumpered that side of the switch and the scope powered up. For now it's fixed. But I really doubt I'm going to find the proper replacement switch unless I rob it off a carcass. So I'm thinking about a more permanent solution.
While I had the Regulator and Inverter boards out I looked them over real good. They both have original factory caps. No bulging or leakers that I could see. But I'm now definitely going to order replacements and get it done soon. And figure out what to do with the power switch.

That is one thing I'm afraid I can't help you with. My one spare is already in service. :-//
Oh, lookie here... it appears a suitable replacement is still available; a fellow found one and posted about it here on eevblog. You may wanna try and find that switch on DigiKey since Mouser shows them still "On Order".
Also... I stumbled across this recap kit while looking for that switch; it seems a bit expensive, unless you count your time tracking all the parts down as worth more than minimum wage. ;)

Rejoice, Rejoice, all ye on the low-carb diet!
