content: Quote from: ESTechnical on February 02, 2022, 01:54:21 pmSometimes support is rude because customer comes with entirely unreasonable expectations, and then upon finding expectations won't be satisfied starts to be rude first.I would never draw such a conclusion based on the report of a single person, even less if I do not know that person.Cheers Peter

content: A couple of years ago I got a Fnirsi DSO PRO that didn'tcome with a manual. I contacted them asking for a PDF or ifthey could put it on their web-site. The reply was to contactthe seller. I seem to remember that wording of the reply was ok,but this shows that they doesn't care much about the users oftheir products.

content: A bit late but the problem I see in the video could be the touch panel. It looks very similar to what others and I experienced, where parts of the touch panel fail to respond to touch.As user ledtester suggested take a look in the thread I wrote about the reverse engineering. It starts to get into the touch panel problem just before this post:https://www.eevblog.com/forum/testgear/fnirsi-1013d-100mhz-tablet-oscilloscope/msg3425900/#msg3425900This is where it becomes more and more about the actual problem and leads to the reverse engineering.Repairing it is possible with a new touch panel from Aliexpress and some skill. Be aware that the front glass panel can break, which you can read about in the other thread
