A two years agou I buy from Owon two osciloscope (PDS6062(T)+HDS1022M-N ) I am very happy with them , unfortunately with HDS1022M-N I had an accident, I dropped down , now no output on screen and the screen is't illuminated, I did not see anything broken or cracked in it , I change the display with another new but the same problem ... the backlight not working , ater power I hear a "buz" but not relay "dita" , I compare this nois with working device , is just a buzer from mesurment block ,
on the mine board I find just 3,3v power suply , other power suply does not work ...
The Owon enginiers told mabe is a firmware problem !!! the firmware are stored in 39LV3201 flash , mabe somebody have read a good firmware for this HDS1022M-N . or can tell me the pin configuration from J-tag connector from the main board , I want to try to read flash 39LV3201 uder ARM prcocesor.....Somebody try this ?
Thank you ,
Costas
