Headset Accessories - Mics, Cables, & Stands

This can result in no picture, no sound, or both. Sometimes the source device will display an error message, or the TV will display a "no signal" error message. I have even seen cases where HDMI problems cause "snow" in the picture and hissing sounds in the audio. That system used the exact same signal format used by HDMI. Its downfall was its two shortcomings:.

The Hollywood content producers realized that all their customers are crooks who, given the chance, would make thousands of digital copies of their movies and sell them on street corners, in bars, and on blankets at the swap meets.

Something had to be done! Enter HDMI. When you send your HDMI signals through a surround-sound receiver, the source device has to ask the receiver what it is, the receiver has to ask the TV to identify itself, and the response has to be passed back up the line to the source. This whole process is called "handshaking. The first, and easiest, thing to try is to let the units reset and try handshaking again by turning them off, unplugging them from the power, and powering them up again in order.

Leave all the HDMI cables connected during this process. This sounds like a pretty convenient feature, but things can still go wrong. If the various devices don't understand each other, your TV might mysteriously shut off while the DVD is playing, or a miscommunication will cause the TV or one of the components to "lockup" and refuse to respond to the remote control or front panel buttons.

Any time some of the components in your system start to act CRAZY, my recommendation is to go into the menus of all the connected devices and turn off the CEC feature. Of course, doing so is only complicated by the profusion of tradenames for this feature, like:. Just find anything in the menus called "control," "link," or "sync" and turn it off. If that fixes the problem, leave the feature turned off. What's Wrong with Free Estimates? Why an Authorized Servicer? Its downfall was its two shortcomings: It carried no audio, so separate left and right audio cables had to be run between devices, and It used no copy protection.

Well, The receiving device TV could be turned off or unplugged when you turn on the source device, so it can't answer the source's question.

By the time you turn on the TV, the requisite handshaking is all over, and the source device refuses to play nice. The source device "forgets" that handshaking has taken place and refuses to output the HDMI signal. The HDCP data stored in the receiving device have been corrupted. Unfortunately, this cannot be corrected by a simple firmware update, 'cause these data are jealously guarded by the content providers and the TV manufacturers.

Instead, parts will need to be replaced. The TV could be a new type, developed after the source device was produced. In this case the source device will not understand your TV's response and will refuse to send it any signal. A firmware update to the source device is needed. Cable and satellite boxes do this continuously over their networks, so you rarely know it's taking place. DVD and BluRay players may also need firmware updates, which is why all the newer ones want you to connect them to the internet.

If not, an update must be done via a USB port, with a specially-recorded disc, or by actually replacing a part in the player. The surround-sound receiver may fail to interact properly with the source device or the TV.

Again, firmware update s of the receiver can be done through the internet, a USB port, playing a disc, an RSC connection to a computer, or a special computer interface jig. Older models required this to be done by as many as 4 different methods on the same receiver! Newer ones use a single update file transferred via a USB key or over the internet.

So what can you do to fix it? Troubleshooting HDMI Problems: The first, and easiest, thing to try is to let the units reset and try handshaking again by turning them off, unplugging them from the power, and powering them up again in order. Plug the TV back into the power and turn it on. It may turn itself off while you're doing the following steps. No problem; just turn it back on. Plug the surround-sound receiver if any back into the power and turn it on.

Plug the source device back into the power and let it go through its startup routine. Hopefully, this solved the problem. You can start reconnecting cables and components one at a time.

When the TV quits working, you will know that the last thing you added was the problem. Repeat step 4, above, using a different cable. Use the TV remote to select the new input. Leave it this way and enjoy your TV. If none of this helps, You can try running component video cables from the source device to the TV. If it now works, you may want to use the component connection instead of the HDMI cable.

Otherwise, you'll need to have the TV repaired.

HDMI ARC and CEC not working? Try these fixes

Old receivers, vintage receivers, stereo receivers, broken sound system receivers, and more all need some type of restoration. Receivers, which are also known as amplifiers, have the responsibility of interpreting audio and video signals. Once the signals are processed, the receiver pushes it towards a loudspeaker and displays the video signals on a monitor. On the other hand, why would someone want to repair an old receiver when you can just buy a new receiver? After saving a good reason , another reason why you should buy an old receiver is so you can understand how a speaker works. Similar to how we said to create your own custom speaker cable to understand it, we say the same for vintage receivers. And the real deal when buying an old broken sound receiver is you might sink a lot of money trying to fix it. Refurbishing a receiver can drain your money because you have to spend money to get it ready for use. A new receiver is good to go from the start.

Why Your Preamp Hums and How to Fix It

Soundbars were supposed to make TV-watching better and easier. The idea was that, as TVs became slimmer, with less room for decent internal speakers, soundbars could offer better sound without making you deal with the complexity of wiring up a half-dozen speakers and navigating the often-confusing menus of an AV receiver. We also consulted a couple of soundbar makers to find out what the most common setup mistakes are and how to fix them. The root of many of these problems lies in the HDMI technology used for most soundbar connections.

You can check connections quickly and there is less cable to tangle. If both speakers now work, the problem is in the turntable, CD player or tape deck. Such repairs are best done by a professional.
