OWON SDS 1104 power issue
« on: September 07, 2024, 06:49:49 pm »
Hello everyone. My oscilloscope has the issue of not turning on. Anyone with its pcb layout or  schematic diagram can send it to my email analogpro762@gmail.com. Thanks in advance

Usually, schematics are not available for these scopes.

Did you measure voltages on the power supply?
Hehe, spooked my friends with an exploding electrolytic capacitor the other day 😁.

Try a performing a factory reset - no I don't know how to do it on that model, you'll need to find it in the manual or web search.

Does the owon use a backlit LCD? If so, check the backlight.

Maybe wiggle the display connector around and see if that helps.

If you have another oscilloscope, probe one of the display data lines and check for activity.
