Why can't I get sound out of my TV?

LG 50UH5500

Episode 1538

Al from Roseburg, OR

Al has an old receiver and he wants to connect his TV to it. He bought one, but he's not getting sound from the TV. If he connects it to the Blu-ray player, though, it works just fine. Leo says that he'll need to go into the LG menu setup and disable the onboard speakers in favor of external speaker output. Another possibility is the DAC may not understand the TV signal because it's encoded, while the BluRay Player is using unencoded PCM audio. Al should figure out what audio the Blu-Ray is sending out and see if he can duplicate that setting on the DAC.

What is the difference between OLED and QLED? Scott says that OLED is Organic Light Emitting Diodes, and is based on organic chemistry, or carbon. That's how it makes light. QLED, on the other hand, stands for Quantum Dot Light Emitting Diode, and it's just a higher end LCD TV. The light source behind the panel is using quantum dots, including LEDs to illuminate the image. They are completely different technologies. But the "QLED" term confuses people, and they may think they're getting a special OLED screen, but they aren't.

How do I connect my TV to my Bose surround sound device?


Episode 1533

Jeff from Sunland, CA

Jeff has a Vizio 4K TV with a Bose surround system. He cut the cable recently, but now he doesn't know how to use his surround sound system with the TV because it doesn't have audio out. Leo says most systems now connect audio via a SPDIF or TOSLINK optical connection. The Bose should have an optical connection to it. He'll also need a TOSLINK cable. There's different connectors, so he'll have to see what his Bose wants, and what his TV takes. Monoprice makes them for pretty cheap, and Amazon Basics does as well.

Scott Wilkinson says he went and saw FIRST MAN in IMAX because the moon walking scenes were shot primarily with IMAX cameras to get a larger, taller image. Scott says that is the trend now, shooting a portion of a film with IMAX in order to make those scenes far more immersive and dramatic. Scott says that there's now a program called IMAX Enhanced, which brings that experience into the home by filling the 16x9 screens of today's TVs with additional content. No letterboxes.

What wireless headphones should I get for watching TV?

Sennheiser RS 120 II

Episode 1532

Seth from Long Beach, CA

Both of Seth's parents are now hard of hearing and they need headphones to watch TV. Is there a system that can do it for them? Leo says that hearing aids now can pair to the TV. So if they need a hearing aid, that's a good feature to get. But if he wants headphones, Leo got his mother a pair of Sennheiser wireless RF headphones. They work much better than Bluetooth.

Why don't I have a channel guide with an over the air DVR?

Episode 1531

Jerry from Hatfield, PA

Jerry has a Dish DVR which can receive over the air signals. He saves the channels and gets no information on programming. Leo says that's because the DVR isn't getting a channel guide in the over the air signal. Channels used to include that data on side ban channels, but they may have stopped doing that and as a result, his DVR can't get the channel guide data. That's why TIVO charges a monthly fee, for a channel guide.
