What is the role of the two adjustment knobs of the TV high voltage package?

The probe features a double-headed needle model 058-JJ-5.7L, with round needles at both ends, each having an outer diameter of 0.5 mm.

Equipped with a single-chip microcontroller STM32L151CCU6 for advanced control and performance optimization.

The TV high voltage package includes two adjustment knobs. One is used to fine-tune the focus, while the other controls the brightness. It's important to note that the brightness adjustment directly affects the anode high voltage. Therefore, avoid increasing the brightness too much, as this can lead to higher levels of ultraviolet radiation, which may be harmful over time.

Adjusting the knobs is straightforward. First, display some content on the screen, then turn the knob slowly while observing the visual changes on the display. This allows you to see how the adjustment affects the image quality in real time.

Once you've achieved the desired settings, it's a good practice to apply a few drops of candle oil into the gap of the knob shaft. This helps prevent the knob from loosening over time due to repeated use, ensuring long-term stability and reliability.

Proper maintenance and careful adjustments not only improve the user experience but also extend the lifespan of the device. Always follow the manufacturer’s guidelines and avoid making sudden or extreme changes to the settings without understanding the implications.
