How to diagnose a hardware breakdown?

Do these tests:

Check through the Engineering Menu: ##4636## Go to Equipment Testing → If the test doesn't pass, the problem is the iron.
Visual inspection: Light a flashlight on the LED module (near the camera) if you see blackening or bloating, the LED is burned.
