content: Hi Community!I received my recently bought SDS7102 from my dealer and I began to work with it. I was amazed about this fantastic DSO, it covers all my needs and I was very happy. Unfortunately since yesterday it doesn't work anymore. What happens?The DSO 'inside' works well; any signal input on channel 1 will be displayed on screen,BUT:I cannot change, choose or set anything with knobs or buttons!This means, all buttons and knobs are out of order - turning or pressing doesn't affect the display.What I see is just the waveform as adjusted last day before the problem today arised and this means to me that internally the scope works well. But the connection to the human has brokenDo you have any idea about the reason for this malfunction? Did it switch to a 'demo mode' for using on exhibitions where people should not 'play' with the DSO?Is it possible to make a reset on the firmware (possibly by pressing some 'mystery buttons' together when switching power on) and would it help in this case?Thanks a lot for giving me some hints and have a nice day!Rudi

content: It looks like OWON is having some quality control issues now that everyone wants to get one.I received a broken SDS7102 two days ago: it powered on but as soon as you would press a button it froze. Sent it back to the distributor and I'll get a new (hopefully working) one a.s.a.p.I assume yours is still under warranty so your best bet would be to contact your distributor.

content: Hi David, this makes me really sad because I spent a lot of money to buy the scope and now this desaster. I hope, my dealer will repair or change the unit or this is done quickly from the company (where carrying the DSO takes a lot of time).Does anybody have some experience with the repair department of the manufacturer?

content: Quote from: rubberdog on January 27, 2012, 09:16:46 amI see you are from Austria?Where from you purchase it. (no need tell name but only if seller was in Europe or if it was some eBay chinese "whoever" seller?)If you bought it from EU area and seller is reputable seller/distributor/reseller situation is good.Ask seller first!If seller do not repair it or change it you have still extremely good choice. Take contact to Owon, write polite letter, send model/serial number and short simple explanation about fail (front panel buttons and knobs do not work at all) and ask RMA handling asap. email address is: service at owon dot com dot cn(in this case they may give free shipping to you after they have accepted started RMA procedure for this failed unit. Follow exactly instructions about delivery they give. It is easy with DHL but some simple shipping paper works need do so that there do not come any extra customs and VAT, not in China end to Owon and also not when it is coming back to you.)Note: In China is still Spring Festival time. Next week is normal but rush. Of course there are now queue becouse all email box are full and it take time they handle these. If you send letter to Owon it may take now more time before you get answer. Next week they handle queue.Owon is reputable company and of course they take care about this fail. In case you have purchased unit what factory have made for overseas markets originally.In case you have purchased from some chinese grey sellers who sell units what are not made/sold for overseas markets situation may be more difficult. I hope your situation is not this. But also you still may get some help from Owon service.I am one Owon reseller. Also we have Owon service in Finland but only for devices which have been purchased from us (exept if separate. (Unless otherwise agreed.) Also I can try give some kind of help if need. You can send PM to me.-aghp

content: Hello aghp,your mail makes me happyYou are right, I bought the equipment from the Austrian dealer but unfortunately technical stuff comes not earlier than monday. Then I call again and hope, I get a RMA and can initiate the repair/change without any further problems. I'm quite relieved that OWON makes also a good job in support.Have a nice day!Rudi

content: I have purchased a brand new Owon 7102 in 2013 january, from an Ebay.de seller.The unitstops responding: knobs doesn't work while the display does. Sometimes it works properly for weeks, but sometimes it freezes and won't work for days. What do You think: is it a software or hardware failure? The problem appeared on the 1st day I have tested the unit. Now I have 3-4 months test results.Firmware update already appliedand didn't fix the issue.

content: QuoteI would buy just about anything online.I had a similar being an early adopter of a brand new model Hantek. It was the right scope at the right price at the right time. The eBay seller agreed to exchange it, but I figured it was probably a known software issue by now. After my emails to Hantek went unanswered for 4 days, I voice-Skyped them at their customer service number in China. They got someone who spoke English to document my problem.The next day I had an email with a USB recovery app to unfreeze the scope and new firmware to load thru the memory card. Problem solved.Lilliput is the largest electronics manufacturer in China. I wouldn't be too worried I bought a brick, unless I needed the scope right now. In that case, I would probably return it and buy something else. But this is something that will probably end up being a firmware thing, solvable with a file and an hour of (albeitly YOUR) time. Vs sending it back to the distributor/reseller and creating much more of a paperwork and packaging nightmare and probably getting a new unit that has the same problem. To the average reseller this scope is just another SKU. They don't necessarily know anything more about it (aside from maybe selling points and marketing wank) than the next guy you pass on the street. And they probably only get new stock a handful of times a year, so the scope they exchange with you will probably have the same firmware.QuoteIf you spent the money to buy this scope, Owon trusts you are technically oriented enough to flash the firmware, yourself. They are way happier to replace the few scopes that are inadvertently bricked in the process vs having all of these scopes shipped back and forth between customers and distributors. It comes down to dollars. And there could be minor tweaks/upgrades to the firmware for several years to come.
