A1261 display backlight failure
External monitor works so the computer is basically AOK.
Backlight went out at first, worked briefly each time the machine was closed and then reopened. Then total failure.
Replaced the inverter board, no change. My system wasn’t going to sleep when closed. I then replaced the infrared sleep sensor, backlight came on, for about a half an hour, then went off again and regressed to totally dead now.
I don’t understand why it came back on for that time but failed again as if that sensor board had something to do with it.
The system does sleep now when lid is closed (still no backlight). It’s been suggested that the CCFL are failing. I would like opinions about that and if it they need to be replaced. I also need to identify the correct tubes.
Can anyone help? Thanks in advance!
