Hi!
I have an oscilloscope one day after purchase. Siglent SDS 1202X-E.
Worked during the day and turned off the power button at night.
In the morning the button blinks, but when I press it it goes out and the oscilloscope does not turn on. Now it does not blink and the oscilloscope does not turn on.
Under the guarantee I can not send. I went through 9 circles of customs hell to transport the oscilloscope to my country. Now I can not even think of sending him back to the seller. Especially since I ripped off the warranty seal, hoping to find the malfunction myself.
Tell me where there can be a problem. What are the first steps I should take to find this malfunction.
