If your home television is not working anymore, you may question whether to buy a new screen or call up the classic "TV Repairmen" (a lost art). While the fix might be easy with a little digging, anything complex may cost way too much or be too troublesome to get repaired. Televisions are pretty inexpensive these days so a good approach is to find great deals on a quality TV. A good, relatively cheap brand is TCL, though Samsung, Hisense, and LG are also reliable. Just don't hang the Television over a fireplace!
A tip from "droplets" in the chatroom. Local channels have been moving and changing frequencies for over-the-air television. If you are missing a channel on your TV, hit "rescan" to find it again! Chances are, the channel didn't disappear into thin air, just scooted over elsewhere! If you have a neat tech tip you want to share, hop into our chatroom at irc.twit.tv while watching The Tech Guy!
If you are shopping for a decently large TV with a good price tag, check out products from brands TCL and Hisense. They are Chinese companies that are trying to break into the United States market, so their prices are quite affordable. Plus, they often have Roku built-in, which is arguably better than creating their own smart TV software.
If you're wondering if TVs are secure, they are! Just don't connect them to the internet! It sounds simple, but the temptation can be real for those who want to use apps to go online. If you keep the television offline, it can't secretly watch you (assuming the company behind it is shady). Get an Apple TV or Roku device, which are kept up to date. If your TV gets infected, the issue can even bleed into your network...which would be a huge problem.
Sometimes it can be confusing when acronyms are nearly identical. It would be in consumers' best interest to learn the difference between OLED and QLED before browsing for new TVs. OLED stands for "organic light-emitting diode" while QLED stands for "Quantum Dot LED" (according to Samsung). Quantum dots are extremely small semiconductors that backlight a Liquid Crystal Display. Many people think "QLED" was a label intentionally chosen to look similar to "OLED", despite not being the same technology.
Tom purchased a new OLED TV and it brought him to do research into the average diameter of an atomic nucleus and cutting circuit lines. Tom wants to know how production facilities are able to cut circuit lines so small and address the wiring grid within so that they don't overlap one another. Leo tells Tom that the process is called Microlithography, which he explains is similar to the idea of silk screening: Painters paint on a screen of silk and then apply ink to it, and the ink goes through the part of the silk that isn't painted. It's a fascinating process.
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.
Jerry wants to know if he can bypass local stations and still get network programming. Rich says networks are all setup to route through the local station. He can't really get a raw feed that bypasses it.
Tim has a friend that developed a program called TV Guardian that removes all the bad words in movies and TV. Rich says that cable is starting to allow more and more profanity, so a device like this can be a good idea.
