Solved! I have an acer laptop that powers on but monitors starts flickering, dims after

[pepibond]

I have an acer laptop that powers on but monitors starts flickering, dims after 5-10 secs and the laptop goes to sleep. I see there is a white and black wire going into the monitor from what think is the wifi card. Could that be a connection problem?

There is also another block of wires wrapped in black that connect to a dock right above the keyboard, covered by the bezel and they also go in the monitor.

Please, help.

Hello pepibond;

Is your LCD a CCFL or LED backlit version?
Could be a bad backlight tube or possibly a bad FL inverter if its a CCFL tube.
Here's what a backlight replacement job looks like:

monitors starts flickering, dims after 5-10 secs and the laptop goes to sleep.

I'm starting to think its a different problem. When its a backlight or FL inverter the laptop normal stays on with just the screen being dark.
