HDMI

Episode 1396

Dan from Chatsworth, CA

Dan got a new cable box with Spectrum, but after a week he started to get an HDMI error because his connection has been "compromised." Scott says that the first thing to try is to power cycle the cable box. That will reload all the standard default settings. It could also be a faulty cable. So replacing the HDMI cable could solve the issue. Scott also says that being an older TV, the connection could be choking. Or maybe the HDMI connector could be failing.

Mark from Sandy, OR

Mark is having issues with his mobile phone because it keeps turning down 75% of volume when he plugs it into his aux jack on his stereo.

How can I connect my home theater to my TV?

Episode 1179

Michael from Monrovia, CA

Michael bought a home theater in a box, a Panasonic A/V receiver, and a 55" Samsung TV. He has Dish TV service. He's having issues hooking everything up, though.

Leo says that everything should go through the Panasonic A/V receiver. He needs to connect the components like the blu-ray player with HDMI cables to the HDMI input on the Panasonic receiver. Then there should be one HDMI output on the receiver, and that will go to the HDMI In on the TV. If he connects the receiver to HDMI 1 on the TV, then the TV should stay on HDMI 1 all the time.

Episode 1138

Richard from Hacienda Heights, CA

Richard's Verizon Wi-Fi router won't work as a wired router, only Wi-Fi. Leo says that's bizarre because he would need to connect his router to the modem. Leo advises asking Verizon if it's possible to buy his own modem. He should get a DOCSIS 3 modem. The added benefit is that he won't be paying rental fees on it.

Richard should keep going back to Verizon and make them fix it. If they can't, then he has a case to go with another provider. The hardware layer is working if there's a "link light" lit. So it may be trouble on Verizon's end.

Steve from Canoga Park, CA

Steve has a car stereo and he wants to connect it to home speakers. Leo says that he's got the resistance mismatched which could cause some damage.

Episode 1105

Randy from Bakersfield, CA

Tim is having an issue that he can't connect with his mac. Leo says he should try and reset the router by unplugging it and plugging it back in. If that works, then the router just needed to be reset. But you can also reset the wifi on your laptop by turning it off and on. Tim tried that and it disconnects after a few minutes. Then that indicates a bad router and Tim should contact his ISP to get a replacement.

Why do I get an error whenever I try programming my ham radio through my computer?

Episode 994

Gordon from Tarzana, CA

Gordon has a BaoFeng UV5R+ ham radio, and it keeps displaying an error whenever he tries programming the radio through Windows. Leo says that less expensive ham radios don't have an ideal user interface to allow the user to troubleshoot easily. Leo suspects that the USB cable is broken, but he also suggests making sure the drivers for Windows are installed first.

The Chatroom says it's the "prolific driver" that's causing the connection. They recommend using Chirp on Windows to find it.
