I have tried all past post and thread troubleshooting methods (unplug, remove battery, hold down keys for 12, 20, 60 seconds, tried starting up with screen at a 45 degree angle) don't have a solution yet. I have an Acer Aspire 5552-5619 ( i know ancient, but up until now it has been very good to me) and it powers up but no screen just blank cannot get up bios or anything any suggestions? (i can hook up an external monitor, but need main screen to work when out of my home)
1. Turn the laptop off (not sleep or hibernate but off).
2. Connect an external monitor to the laptop.
3. Turn on the external monitor.
4. Turn on the laptop.
NOTE: You may have to press an "external monitor" button. Could be the f4 button or a button with two monitors on it, for the external monitor to work.
If you can see fine on the external monitor, then your attached display, or the ribbon cable that connects it, are your problem.
If you can't see on the external monitor at all, or the problem occurs on the external monitor as well, then it is probably the graphics card/GPU that is the problem, which may require the motherboard be replaced.
