Member: 1702322 Status: Offline Thanks Meter: 1 | ok, i,ve found the full of that picture with a big logo "digi tel" in the centre of it...(Y) it's on the right place, TO make the photo unusable.. no problem.. How can i tell if a capacitor is faulty, because i have somewhere a short. It was because of a water damage, and there was oxidate on c252's area, maybe the c342_RF is faulty( i can't figure out the number on the photo, but i think that is its number). |

Member: 1702322 Status: Offline Thanks Meter: 1 | I see. But unfortunately i killed all the, corrosion, so nobody can see which was corroded. And i dont have the knowledge to unsolder anything. But now i see that near the dock connector there is missing FL10 and FL11 i don't know if it jumped off the board or is it originally missing. |

Member: 1702322 Status: Offline Thanks Meter: 1 | The multimeter shows that they make all short.. I'll go crazy because of this... When i connect to the charger none of them are heating, but when i touch the two feet of the cap it's beeping...the battery - and + is bbeping too, the cap's all two feet beeps on the GND. Isn't any method to check those caps without soldering them? How should i test them? Please (( |
