1. The power cord is not properly connected
This may seem obvious, but make sure the power cord is connected to the back of the touchscreen and plugged into a power outlet. If it looks like it's connected correctly, disconnect and reconnect both ends of the power cord to make sure the cable isn't loose.
2. The power cord is damaged
Verify that the cable that powers your touchscreen is not damaged or damaged by replacing it with another cable.
3. Defective power supply, button, power strip or inverter
If, after following the steps in the section above, your touchscreen still doesn't power on, the power supply may be malfunctioning. If you don't want to replace it yourself, we recommend that you take the touchscreen to a repair center.
If you have a touchscreen and plan to try to fix it yourself, turn on the touchscreen and verify the power connection. You can do this by disconnecting the main power cord and reconnecting it to make sure it's not loose. Also, confirm that the power button cable is properly connected to the motherboard.
You can also test the power supply with a multimeter to check if its output voltage is correct. If the voltage output is low, it is likely that the power supply is broken and needs to be replaced.
4. Loosely connected hardware
Every time your Veron touchscreen tries to turn on, it will run POST. If the hardware component fails this test, the touchscreen will not continue to boot. Unplug all cables from the back of the touchscreen. Open and reinstall all expansion cards and memory. After reinstalling these cards, make sure all cables are securely connected by disconnecting and reconnecting.
Once everything is disconnected and reconnected, connect only the power cord to the back of the touchscreen and try to turn it on. If the touchscreen is on, you can turn it off and reconnect all cables.
5. The motherboard is damaged
If the power connection looks normal, but the touchscreen still won't turn on, the motherboard may be damaged. First, turn on the touchscreen and visually inspect the motherboard. Look for any inflated or burned capacitors.
If you're soldering on your motherboard, some solder may have two or more contacts connected that shouldn't be connected. These incorrect connections can cause the touchscreen to fail to turn on or boot.
