ol Dho804 Oscilloscope, but there is a problem, I connect the attached power supply to the 220 v power source and turn it on but the display stays black and no boot to the operating system, What should I do?
That's actually low-cost. It costs a bit more than that in Europe. You could have bought it from an official Rigol distributor from (say) Europe, and got it shipped to you, I suspect for about $600-$650 including shipping, if you were OK to pay import duty on it when it arrived to you.
I know that doesn't help now, but for future test equipment purchases above (say) a couple of hundred $, it might be safer to pay the extra amount to buy from an official distributor. But even with a distributor, you'd still likely have to swallow any shipping charges if things go wrong and you need a warranty repair.
I'm sorry if I missed it in the messages and replies, but has it ever worked for you? And if it did, what was the last thing you did before it stopped working?
I must admit that I do not know how the customer protection laws works in Egypt, but I am almost sure that if you will contact the China vendor and ask for exchange or money back, they will arrange for equipment exchange.
Okay back to the first question, has it ever worked for you. The second question was more along the line of, it worked for a while, then one day it wouldn't boot. If the latter is the case, what was the last thing you used it for?
The Rigol service just sent me the mail and said that "please try the following solutions:
Press the power button and quickly press the BACK button on the front panel multiple times. This may reset any incorrect settings.
Alternatively, place the latest firmware on a FAT32 USB drive, power on the device, and follow the on-screen prompts to upgrade the firmware.
If these steps do not resolve the issue, please contact our support for further assistance by 'reply all' via this email.' But I don't know what is he meant by back button
I just bought a new Rig
