Why can't I buy apps in the Google Play Store with my Nvidia Shield tablet?

Episode 1385

Shane from Indianapolis, IN
Nvidia Shield Tablet

Shane has an Nvidia Shield gaming device and every time he tries to buy something from the Google Play Store, he gets an error. Leo recommends clearing the cache, restarting and then resetting his Play account. The problem is that the Nvidia Shield has Android 7 and it doesn't give him access to his Google Play settings. That may leave Shane with only one option — to reset the Shield itself.

Can I leave my TVs on?

Monica from California

Episode 1381

Monica wants to know if she should turn off her TV when she leaves the room or can she leave them on as she moves from room to room? Leo says that TVs use a lot of power. LCDs use the least amount, though. It's about the same as a light bulb. So it's OK power wise. It won't hurt the TV at all since they're rated for over 50,000 hours each.

Is my Plasma TV dead?

Episode 1380

Miles from Long Beach, CA

Miles' HDTV suffered a power outage and now his HDMI port isn't working. Leo says a power surge likely wiped out the HDMI ports. He should check if he has another HDMI input that he can use. Leo says there may be a fuse that has blown and a repair man could replace it. That could restore his HDMI. If not, it's not an easy or affordably fixable thing. A 64" plasma is worth at least trying to get fixed. The chatroom says to make sure the polarity and grounding is correct on his plugs. An electrician can test for that.

This week's gadget is the ONO $99 3D printer that uses your smartphone to act as the platform to print a 3D resin image. The smartphone is providing the visible light to harden the resin as it's printed. That means 3D objects can be created layer by layer using your smartphone’s screen as light source. A rough estimate of the maximum size of the 3-D build is 4.72" X 2.5" X 2".

Leo says what Matt needs to do is create an ISO for them. There's software that does it. Leo recommends getting media server software like KODI. Then he can use the AppleTV that can see it and play it.

Should I buy a refurbished A/V receiver?

Episode 1378

Steve from San Diego, CA
Yamaha RX-V575P

Steve is looking to buy a refurbished Yamaha receiver. Leo says that refurbished devices are best bought from the original manufacturer. That way he can still get a warranty to go with it. All too often, they are brand new devices that were returned, and as such, can't be resold as new. So they're sold as refurbished instead. If he's looking for a great deal, refurbished is the way to go. He should just make sure to get it from the original manufacturer.
