have it brought to the sony repair shop po.
raon might be cheaper and they might even be able to fix it, but... hirap punta raon.. masikip.. matrapik.. madaming tao.. malayo paradahan, jeepney stop, or bus stop, sa pintuan ng repair shop.
the sony repair shop near kalaw has parking 2 feet from the door.
whatever problem you may be able to diagnose DIY-style, you will still have to bring it to the fixit shop, unless you are an electronics-repair savvy..
and no... they do not pad repair expenses, as far as i know..
magkano repair fee? natural, depende kung ano ang nasira.. mura lang diagnosis fee.. they will even advise you if it "is not worth repairing"..

we had experience comparing sony repair shop versus ex-sony technician.. hindi nagkakalayo..
