Loading...How to fix Acer Monitor with PWPC - No Power?
To address a 'PWPC - No Power' issue on your Acer Monitor, consider the following checks: * Verify the AC line voltage (110V or 220V). * Check the voltage of C904(+). * Examine the start voltage for pin 3 of IC901. * Inspect R903, R904, and IC901. * Ensure the auxiliary voltage is between 10V-16V. * Check components IC901 and T901. * Inspect ZD901 and D903. * Check D910, D911, and IC902.
What to do if there is no picture on Acer Monitor?
If there is no picture on your Acer Monitor, ensure that the power switch is in the ON position and the power cord is connected securely. Also, verify that the video cable is securely connected to both the monitor and the computer. Finally, try moving the mouse or pressing any key on the keyboard to bring the monitor out of "active off" mode.
