Questions and answers
must turn on 15 to 20 times to get it to stay on
The Gateway FPD1830 monitor requiring 15 to 20 attempts to turn on and stay on could be caused by failing internal components, such as capacitors or power supply parts. The parts list shows use of electrolytic capacitors like "2200UF 10V" and "33UF 25V," which can degrade over time. Faulty capacitors in the power circuit can cause instability during startup, requiring multiple attempts for the monitor to power on and remain active.

screen comes on and goes off. must turn on 10 to15 times to get it to stay on
Possible causes for the Gateway FPD1830 screen turning on and off, requiring multiple attempts to stay on, include:
1. Power Connection Issues – Ensure the power cord is securely connected to both the monitor and the wall outlet.
2. Loose Video Cable – Verify that the video cable is properly connected to both the monitor and the computer.
3. Power Button Not Engaged – Ensure the monitor’s power button is turned on.
4. ActiveOff Mode – If the power LED is orange, move the mouse or press a key to wake the monitor.
5. Hardware Failure – If the issue persists despite checking the connections, refer servicing to qualified personnel.
If none of these steps resolve the issue, the monitor may require repair or replacement.
