I have this one in with a blown bridge rectifier, replaced all diodes and found BUF405A to be bad as well. A chassis from another nokia which lookes very similar has a BUT18AF in the same position. Datasheets tell me this is not the same part, even while it's not far off. Can i substitute the BUT18Af or do i have to order the original (pain in da ... here)? As well, has anyone experience with this chassis, common faults... I suspect a small lightning strike but at first can't find any more bad parts. Thanks
