Good day!

If your oscilloscope's screen and front panel aren't turning on despite four out of six power status LEDs showing green, there are a few things you can do to diagnose the issue:

1. LED Identification: Typically, manufacturers provide documentation indicating the function of each LED. Look for the user manual or technical documentation for your oscilloscope model. It should specify which LED corresponds to which component or system status.

2. Additional Checks: Since the LEDs are indicating power status, it's likely that power distribution is functioning correctly. However, it's still a good idea to double-check the power connections, especially those related to the screen and front panel. Ensure all cables and connectors are securely attached and not damaged.

If despite the LEDs showing green, the screen and front panel remain unresponsive, it could indicate a deeper issue with the display or control circuitry. Consider seeking assistance from the manufacturer's technical support for further troubleshooting steps or repair options.

Keep in mind that if disassembling the oscilloscope, you should handle it with care to avoid damaging sensitive components and ensure safety precautions are followed.
