Scott Wilkinson

Steve got a new TV and he wants to integrate it into his sound system. Leo says that the centerpiece of the modern era is the TV, and we're trying to duplicate the experience with surround sound. Leo says that the existing receiver will probably not work. Steve will need an A/V receiver. He doesn't want rear speakers, though. Leo says Steve at least needs a subwoofer and a center channel. He should get the TV at eye level and have the speakers on either side of it. He could use a "phantom" center speaker. Not nearly as good, but it will do the job.

Why does my computer fan make a noise?

Episode 1147

Gary from Long Beach, CA
Computer fan

Gary bought a computer from GoodWill that they have put together. Leo says that's a great idea, and he got a great price on it too. But he's noticed that the fan is making noise. Leo says that could be a wire that has gotten in the way, and that could be dangerous. It could short circuit the wire and cause a fire. So Gary should open up the computer and make sure there's nothing hitting the fan. If that's not the issue, then the bearing of the fan may need to "warm up." They can easily be replaced.

Why does my LCD screen flicker?

Episode 1147

Roger from Pasadena, CA
LCD monitor

Roger's LCD monitor is "flashing" after about a minute and then settles down and works again. Leo says that it may be a bad cable, which would be an easy fix. But it's more likely that the monitor is aging and the transformer or power supply is starting to fail, requiring it to "warm up" before use. It's not really worth fixing. Monitors are so cheap now, Roger should probably just get a new one.
