REASON FOR FAILURE:

1. PCB Components Life Ending-Capacitors. Bridge Rectifiers. I/O Isolators. Controller Board ICs, Power Board ICs. Inductors. Transmitters ICs etc.

2. Screen Invisibility-Display board or Touch screen will become invisible due to Display board life ends. damage due to Vibration through machines. due to Moisture. Dusty, Heat etc..

3. Feather Touch Keypad Not-working-- Due to long year working or due to improper using of keypad. due to minor components damages Keypad PCB layers & copper tracks.

4. Power supply or 1/0 side failure- Due to high voltage supply.

5. HMI outer body-Due to continuous machine vibration, outer body (case)
