Hello,
I did some repear on mechanical part of the laptop. Unfortunately, I did not remove battery before.
When connected the screen to mainboard, connector slipped and its metallical casing caused a short cut on screen connector pins.
It seems that screen backlight was not working anymore. But... When plugging the external power supply, the screen was correctly ligthed at full power. When dimming the backlight, it started flickering. After some minutes, the screen was not
backlighted anymore, with or without external power supply.
I found out that, on the bottom of the motherboard, just under the connector.
One component is blown. It looks like a 0603 capacitor.
I would be pleased to change it instead of buying $300 refurbish chinese motherboard.
Here are one picture right after the damage and one after some cleaning.
Do you have any advice on which value to use ? I thought doing a trial and error, starting at 100nF and increasing 10x each.
Thanks for your help.
Julien
