on my laptop the screen is visible but very dark. its not the brightness settings, so i imagine perhaps the bulb has gone but would love someone cleverer than me to confirm this, or suggest what i should do next. funny thing is that when you turn the laptop on, the 'acer' sign comes on fully lit, then it goes dark. that's why i thought perhaps its not as simple as the bulb going.

all help much appreciated.
thanks,
gary

Quick diagnostic checklist to isolate whether the laptop lid, cable, inverter/backlight, or the graphics board is at fault.

Start with an external monitor: connect via VGA/HDMI and boot. If the external display is normal, the motherboard/GPU is likely OK and the problem lives in the screen assembly (panel, backlight, inverter, or hinge cable). If the external is blank too, concentrate on the GPU/motherboard (reseat RAM, run BIOS/POST checks). A simple power reset can help flaky hardware: remove battery and AC, hold power 20–30 seconds, then reboot.

Do a visible-image test next: with the laptop on, shine a bright flashlight at a shallow angle across the LCD. If you can faintly see the desktop, the LCD matrix is working and the backlight or inverter is failing. If nothing is visible at all, the panel itself may be dead. While gently opening/closing the lid, watch for flicker or changes in brightness—that points to a damaged or loose display ribbon/cable in the hinge.

Typical repair sequence and cautions: replace the inverter first on older CCFL-backlit machines (cheapest). If that does not help, the backlight tube or the whole panel may need replacement. On LED-backlit models there is no inverter and a failed LED array or panel replacement is required. Parts cost ranges widely; inverter boards are usually inexpensive, panels are pricier. Do not probe inverter/backlight wiring while powered—these parts carry high voltage. If not comfortable with tight screws, fragile cables, or soldered parts, seek a professional.

For targeted help, post the laptop make/model and whether an external monitor shows output; include whether the faint-image flashlight test changed anything. Following up with those details will allow others to suggest exact part numbers and step-by-step guides. Thanks to and for moving this to the right forum; the OP should add the model number for precise advice.
