Hello, I was just gifted with this very cool Sony TFM-C480L Alarm Clock and some features dont work. I managed to fix a bad solder on the lamp of the sound radio so it now gets good signal, but the volume is very low, I can only hear with maximum volume and no movements or noise, the quality of the sound is good however. The second thing is quite weird, I can set it to an alarm at a given time, with a buzzer or thé radio, as the button shows : button down for radio, up for buzzer. However, no matter the setup, it always goes for the radio. I opened the thing but cannot see a visible flaw. Any ideas ?
