Like I said back in September: Take it apart, check the power supply voltages.
If they all look OK then maybe there's a bad solder joint somewhere, get your magnifying glass out.
Yes, I'd been avoiding having to resort to that, as it's only 18 months old, with around 20 hours usage !
I think it's got about 10 hours or so left on the trial features.
I bought it long before I really needed it!
I ended up returning it to the dealer. They took about 3 weeks, 3 people asking for my details via email, etc, before arranging a collection.
Then they contacted me to say someone might have "hacked the firmware" so they don't want to know..........
It then took around 5 weeks for them to return it.
Since then I've put it up for a while, feeling extremely pi**ed off about it all.
Been trying to decide what to do.
Eventually, I thought I'd check back here and try again to see if I could find any help\clues!
At this point, I suppose I'm just going to have to do whatever I can.....
I am only a beginner hobbyist and it's my first scope, to learn with.
Can you load the default settings and activate all four channels, then save the settings to a USB stick and upload them here?
Ok, thanks for that. I'll do it......
