Re: Toshiba A300D power problem

just finish with the reflow, it worked. But i hate this kind of reapir, i can never be sure it will last a day, month or year. I think in this situations it is the best to put a new VGA card.

Holla there!
I have A300D 14E motherboard ( DABD3GMB6E0)...In that part was maybe a fuse or somethin else thats was completely fried, and the motherboard was without power or any indicator to show a life, I remove the fried component it and now is power on, tested with external monitor is working...but now I dont know is it a fuse or some another electronic component.. Need a little help

P:S: I saw pictures here from the same motherboard and I noted that is missing a cable that connect the down right side from the hole 43 to Hole 6( CN17 to CN5)

Re: Toshiba A300D power problem

no no no it`s not fuse it`s capacitor...big one i see,most likely on backlight power line...don`t put fuse...

Re: Toshiba A300D power problem

Ah yeah! Crnogorac be nice and explain me which capacitor I need to put there.. The fried component was with a white colour...!
Daj molim te budi malo precizniji Nemam pojma iz elektronike al mogu da sredim ako dobijem instrukcije.

Re: Toshiba A300D power problem

I guess you will need the schematic to find out what the capacitor should be

Edit: Think I found the schematic, see attached.

Check Page 20, top right for C26. Schematic says 10u/25V_1206
