Helo.
I bought an oscilloscope on Ali. But it does not work at all!
The seller does not accept it back. I want to repair it.
The oscilloscope does not turn on at all.
All voltages on the power supply are OK.
Please see the video.

And tell me the results.

Hello, I measured the voltage.
I think everything is OK

I read your message board and assembled the TTL-RS232 circuit

Then launched SecureCRT.
It is visible, I turned on and off the oscilloscope 2 times.
The terminal displays only two characters "O" & "M"

The oscilloscope does not work.
Where I made a mistake?I tested it with different SD.
Probably this is not software, but hardware failure?
Please watch the video.
P.S. The connection of RX and TX is correct. Otherwise nothing works at all.

Well, if I replace K9F1G08U0E, can I program the oscilloscope with a SD card?
I'll put an empty chip and program it with an oscilloscope and SD card. Is this possible?

Sir, yes, you can program the new chip K9F1G08U0E with SD card.

Then launched SecureCRT.

The same result as my. It is as if ... No information was recorded in the Nand memory of the oscilloscope.
I have tried with SecureCRT, with PuTTy, with TeraTerm and the result is always the same, no information is shown on the PC screen.
Either we do not know how to use the program, or it's what I'm imagining (all oscilloscope data has been erased from memory).
Anyone who knows how to use these programs could post a video showing how to configure and use SecureCRT connected on an oscilloscope?

O mesmo resultado do meu. ? como se... Nenhuma informa??o estivesse gravado na memoria Nand do osciloscopio.
Eu já tentei com o SecureCRT, com o PuTTy, com o TeraTerm e o resultado é sempre o mesmo, nenhuma informa??o é mostrada na tela do PC.
Ou n?o estamos sabendo usar o programa, ou é aquilo que eu estou imaginando ( todos os dados do osciloscopio foi apagados da memoria ).
Alguém que sabe usar esses programas poderia postar um video mostrando como se configura e usa o SecureCRT conectado em um osciloscopio?

Sir, sorry, we can't make a clear judgement about where the problem is.
Please contact your seller to return factory for repair.

With my case it is a bit complicated because I am in Brazil (The country of corruption) !!! For me it is not possible because posting parcels with addresses here within Brazil is already absurd what the Posts charge. imagine posting an order to China! Not to mention that I will be re-taxed at the Customs of Brazil, when I re-send the oscilloscope and the rate here is an absurd 60% on the value of the product.

Com o meu caso é um pouco complicado pois estou no Brasil ( O país da corrup??o )!!! Pra mim fica meio inviavel pois, postar encomendas com endere?os aqui dentro do Brasil já é um absurdo o que os Correios cobram. imaginem postar uma encomenda para a China! Sem contar que serei taxado novamente na Alfandega do Brasil, quando me re-enviarem o osciloscopio e a taxa aqui é um absurdo 60% sobre o valor do produto.

It's been a while since I visited this forum. And this time I'm here to thank you Amy for helping me solve the problem with my Hantek oscilloscope. My oscilloscope was perfect with this new motherboard, I thought it was better than before.
Many thanks friend ...
