My roommate finally convinced his parents to get a new TV (they had a rather old and basic 19") for their living room. They ended up getting a Sony KV-27FS13 which meet all their needs. It was bought in a city an hour from where they live. After they got it home they were complaining about a loud sound it made when it was turned on. Both my roommate and I thought they were exaggerating. However, my roommate just got back from visiting his parents over the weekend, and informed me they weren't expurgating. They turned it on and the sound made him jump. Anyone know anything about this? The TV seems to work fine after it starts up. Is this normal for this TV?
