DSO4202S don't start

I purchased DSO4202S on AliExpress1.5 years ago
The oscilloscope served excellently.

Recently, symptoms have begun to appear:
When turned on, the display backlight blinks at intervals of about 1 second. All buttons are lit.
The oscilloscope does not load.
A few minutes later, the oscilloscope starts working normally.

Loading time is from 1 minute to 30 minutes ...

I disassembled the device and checked all supply voltages.
All voltages are normal.
I don't see any pulsations ...

Advise where to dig?
Should I write to the seller?
Where can we fix it (Novosibirsk)
Share your experience ....
