JYETECH scope

Hi!

after i got it assembled it only worked for a couple of hours and then it stopped responding
i didn’t even had the chance to use so so i can do some measurements while it was still alive… :unamused:

now only the backlight of the display and the red led comes on… i did some inspection to the
board and i also checked the +VRAW and +5V pads and the voltage looks fine… i really don’t
know what else to check

here’s a photo… i hope somebody has an opinion and can help with it.
