We have information about the back light tests. But you say the back light is on so why would you suspect the back light and not something like the old function key video switching function?
I have an acer aspire 5920g laptop and I need your advice in an- apparently hardware problem.
Some months ago, the screen started to flicker a bit, and went off and on by itself sometimes. At some point though, it never turned on again!
The laptop works, because I have image when I plug it to HDMI. I removed and re-inserted the cable that connects the motherboard with the LCD. But still nothing.
After doing a bit of research, I thought it must be the inverter or the screen died.
However, one day I moved the lid a little bit, and got image on the screen for a few seconds. Then it went dark again! Btw, the backlight is on.
Any suggestions on what should I do??
Your help is much appreciated!
