Question about Computer Monitors
I opened up acer icon for projector i think by mistake, when i closed icon on taskbar, external monitor no longer responds, my laptop screen was broken hence the external monitor, but now when i power off/on i cant get display on external monitor, i've tried toggle switch fn + f5/f6 ? I've tried connecting to tv which used to work as monitor also, but not now, is there a simple keyboard function to revert as it is only since i opened that acer icon on desktop ??
Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.
