I have the exact same problem as the guy made this video.
The laptop (a 17' acer) starts normally and after around 10-20 minutes starts doing this. The screen is ok and suddenly blinks for some milliseconds and then back on and again after 1-3 seconds and so on.
I've replaced the monitor's inverter but still no luck. I connected another laptop screen using the inverter's output and the other monitor also flickered. I believe that after a while something gets heated up and resistance is increased, causing this phenomenon.
At the moment there seem to be three causes for this:
- Faulty screen cable. This laptop has one cable both for the inverter power and the screen data.
- The VGA chip (unlikely)
- The main power to the laptop isn't stable (because of a faulty charger maybe) and causes the inverter to have insufficient power to keep the lid lighting.
I believe I should start with the cable but since I've already bought a part I would like to be sure this time.
Is there a way to check that it is not the cable and if no is there any way to identify the problem at all?
