Help me please!! I've just received a 32PF9976 today, and I checked the servicemenu right away. It said TX21EU-2,2_07771, so I thought that I was saved. But when I turned the contrast below 97, the TV started to buzz right away. I thought, that this problem only appeared on TVs with firmware version 1.3. So what should I do? Shall I get a new TV and hope that it doesn't buzz or can I get upgraded, so the buzzing stops? Has anybody any experiences with this? Please help me, so I can enjoy my new TV.
