Hello,

i have a problem that my UTComp only boots sometimes.
Often it dosent start, only the buzzer make "click cklick cklick" noise. I also have 0V on the 5V for sensors.

If i disconnect the display, it make "beep" and i hear the buttons working, as soon as i plug the disply in it is silence.
The display cable itself is good, if i only connect the cable without display it starts too.

Display damage?

Greetings

Seems like power issue. It may be internal power supply issue or short circuit on external sensors (and high current drain).
Is display sometimes is working or is it dead at all?
Could you open UTCOMP and make picture of 2 green capacitors inside? If they are faulty it may not start also.

Same Problem here, think theres a Problem with a sensor draining to much current.
Disconnect Sensor by Sensor and observe it
