Hello! Couple years ago bought this scope. Now screen is blinks and half screen not lighting. Half leds in screen not working. And led driver on max brightness not working correctly. Led driver chip is uknown. Google doesn't know about this chip. I can buy leds, but i can't buy led driver. Can anybody say, what chip is using there? Or where i can buy new display?

Sir, this should be the LCD screen is broken.
Please disassemblethe scope, and check the model on a label on the LCD.
And purchase a new one on ebay to replace.
If you are not sure of the model, please upload a picture of the LCD.

Instead of LEDs, I connected a resistance of 70 Ohms and measured the voltage - continues to jump, as with LEDs
