Just wanted to give you an update -
Yes, it turned out to be the capacitor c807 problem. My supplier sent me a new one for free - and I've done my first electronics soldering job. Not hard to do, and much good advice to find on the net. And of course it brought my Vu+ Duo back to normal operation.
Again - thanks for all advice.

Thanks again for all advice - a short update:
I believe it is a overheating issue -
Earlier today I decided to test the fan, and removed the top lid again. Removed all in/outputs except power cable, kept HDD connected. After about 15 minutes of red led the box booted normally, and has been running normally all day (about 7 hours) without freezing or crash. I've stressed it by changing channels frequently, and left it on. The fan started on boot, and has been running normally all day. But as I understand it, the capacitor c807 cannot handle too much heat, or will burn/break after long time use.
I suspect that the fault will reappear if I put the lid back on, and connect everything again - but I will try. It may also confirm that the problem is overheating...
@Meekat: thanks for the tip, mate. I've just discovered this forum - should have been here for years :-)

A good night's sleep may often clear thoughts...
Possible reasons for problem:
1. The cooling fan:
The fan is software controlled, right? But should it start on boot. I'm running a test now, leaving the box on (red light, no boot). The fan is not moving.
2. Power supply:
It suddenly occured to me that during the summer we had one day with heavy thunder, which may have caused power failure, or worse, current failure. This may have done damage to the box. But then again, would it even start and run normally at all - even for a short time?
3. Capacitor c807:
I've seen referrals to this capacitor causing a problem, not sure what it does. Something to do with the power supply? Can this be identified or replaced by an amateur, or does a replacement of the power supply fix this?
4. Kernel/driver problem:
Early in the process I flashed the official image 1.7 (and have done several times since then) - and then flashed a new image (BH1.7, Openvix, VTI). I'm not sure, but when you flash an official stable image, it's like installing a new operating system on a PC - it's the closest you get to a factory reset. Right?
To conclude - I'm pretty sure it's hardware related, and if it's the fan or power supply it could be replaced.
@MeeKat: At some point, when you have an image that is stable and works fine, you don't want to upgrade just for fun. I tried BH2.0, and reverted - because I felt I didn't really need the new features. I used to download softcams via TSPanel or other plugins, and at the time I couldn't find the right package and install it manually.
Thanks for all the advice so far - I will get back if I can find a solution (other than buying a new receiver). Luckily, I have found a backup receiver (from a provider) so I can watch TV this weekend... But it's like delivering your Volvo for service, and getting a bike as a backup...

Well. BH 1.7.9 was running steady for a long time, and I tried the 2.0 - but couldn't figure out how to install softcams. But that's not the issue here...
I've opened the box, removed some dust, cleaned the fan. It seems to be in order. Decided to test with the top lid off, to check the fan - but then it wouldn't start... Just the red lamp. Put the lid back on - still just a red lamp.
But then - after about 10 mins, the box starts. I haven't even touched the remote. And - after running for 5 mins, it hangs again... Next: Won't start at all. Red light.
The situation has gone worse during the last couple of days - which indicates a hardware problem. It seems that many have had the same problem during the last year, but noone seems to have found the answer to the problem, other than replacing the box altogether. I fear my vuduo needs to be replaced.

Hello -
I've had an original Vu+ Duo for some years now, and it's been very stable. I have a 4-satellite setup (4 lnb), and for most of the time I've used BlackHole. The last stable image I've run is 1.7.9, and I've used Scam 3.60 to (legally) view TV.
However, the last month I've had a problem:
Randomly, the box hangs - the screen going black, display showing last action, and the lamp is green (reacting on remote). A "hard" restart seems to be the only way out, but then it freezes again after just a few minutes. It freezes on remote signal - changing channel, performing setup/adjustments etc. I've tried several images, and found that VTI so far is a bit more stable (may be just a "hunch"). I've also flashed original Vu+ image 1.7 before flashing other images, but no luck.
I'm suspecting that this may be a hardware problem - or a kernel/driver problem. I've reformatted/initialised the HDD, no fix. Several years ago a had a similar problem with a PC, and it turned out to be a defective fan. Before I open the box, and start fiddling with the hardware - I seek some advice here. I've found other users in different forums also have had the same symptoms, and I've tried the solutions proposed. But so far, I haven't been able to fix the problem. And I'm getting desperate - the PL starts this weekend...
