Dark screen when dim is more than 3 dots
Hello everyone. I have a question what could be in fault when I increase me brightness to more than 3 dots (OS X ui). My screen goes black but if I take a flashlight I can see my desktop and opened application.
So I open the screen and try to disconnect and reconnect the cable.
I saw that the vsync cable was damage so I decided to unplug it and try again.
Now I can increase my brightness to full whiteout my screen goes black.
So my question is : this is a temporary solution ?
What could be in cause ? Inverter ? Or just vsync cable could cause this issue ?
Thanks
Edit : I also saw some flex repair by glue or tape. Can someone explain how to did this ?
Thanks

Hi
So I just change all the component. And the issue persist. More later I can use the mac more longer but the screen loose the backlight again.
When it arrives the top back screen is very hot it could be an issue. Perhaps I need to try smcfancontrol to avoid that ..
Is this a good question?
