Acer Travelmate 5310... no backlight

[Waldpiek]

Hello all,

I have a Acer Travelmate 5310, problem is that the backlight does not work.

Tested other ccfl lamp, other inverter, other cable from the motherboard to the screen ,no succes.

Turns out I have no power (Vin) to the inverter board

Anybody here got a clue where this Vin is comming from ? Tried to trace it too some fuse on the mainboard, but got lost..:-)

Board markings : Dellen 06259-2 48.4V401.021





Can make some better pictures if the daughter ever brings back the camera

Thanks for looking, hoping on a solution.

Have a nice weekend, Frans.

Okay...

After spending some time with this board.... found that fuse F2 on the board was broken.

Replaced it and backlight came back to life :-)

Vin comes from B+, you would connect it directly to adapter power.
