Lightning struck my home. All of my receivers are powering on but are not transmitting any audio or video signals. my DVD player and my Apple TV is also not working. what do i do ?

Your probably have power supply damage, but lightning strikes can do major damage in all circuits.

Hello there,

Here is the link to the full manual:

Before connecting your devices...
The signals that enter the TV and connected devices will need to be output in the correct format using the suitable connections. Below are the different types of video connectors. When connecting the TV, use the inputs that are available on your devices that provide the best video performance.
Video performance level Name Aspect Signal transmitted Separate audio connection required HDMI Picture + Sound No DVI*1 Picture Yes

L-AUDIO-R Component video Picture S-Video Picture Composite video Picture RF/Coaxial Picture + Sound No
*1 If the equipment has a DVI jack and not an HDMI jack, connect the DVI jack to the HDMI IN (with HDMI-to-DVI cable and/or adapter jack), and connect the audio jack to the AUDIO IN (L/R) jacks of HDMI IN. (The DVI connector is for video signals only) To enjoy the best visual experience with your system, it is preferable to connect your best devices with the highest quality connections available. For example: your Blu-Ray Disc player or HD Set Top Box with HDMI, followed by your DVD player with Component, then your Video Cassette Recorder with S-video etc.Note: The quality of the picture also strongly depends on the quality of the cable used.
HDMI The High-Definition Multimedia Interface (HDMI) is an all-digital audio/video interface capable of transmitting high definition video and audio signals. HDMI provides an interface between any compatible digital audio/video source, such as a set-top box, a DVD player, a PC, a video game system, or an AV receiver and a compatible digital audio and/or video monitor, such as a digital television (DTV). DVI The Digital Visual Interface is capable of transmitting high definition video, but does not transmit sound. You will need to use the audio connectors of your device (usually Optical/Coaxial digital, or RCA). It is possible to connect an HDMI device to a DVI device using a HDMI to DVI adapter. Component video Component video is an analogue connection. It is capable of transmitting high definition signals. Component does not transmit sound. You will need to use the audio connectors of your device (usually Optical/Coaxial digital, or RCA) S-Video Separate video, abbreviated S-Video and also known as Y/C is an analogue video signal that carries the video data as two separate signals (brightness and colour), unlike composite video which carries the entire set of signals in one signal line. S-Video, as most commonly implemented, carries standard definition video. It does not carry audio on the same cable. Composite video Composite video is an analogue video (no sound) format. This is the connector you should use if you do not have any other connector available, in terms of quality. RF/Coaxial RF Coaxial Cable connection is used for transferring television signals (audio and video) originating from an antenna or cable box to a Television.

Hope this was helpful to you.
Goodluck

You probably need to change the incoming input signal on your tv.

In other words, your audio is coming directly out from your dvd player, and going directly to the audio power amp.

Your video does the same thing, except it goes to your tv. Your tv has multiple places for "incoming" signals to hook in to it. Take a look at where you're hooking your video in - the input should be marked ... something like "Component 1" "Component 2" "HDMI 1" "HDMI 2" ... something like that.

On your remove, there will be a button that says, "Input." When you push this, you will see that your TV brings up an input selection window. Pressing the "input" button on your remote should scroll through the ports on the tv. Briefly pause on each input selection to see if it begins receiving a video signal from your DVD player.

Any time a unit is hit by lightning, it is usually a total loss. While the initial problem may be fixable, other components have been stressed and are likely to fail. Most shops won't work on these units because of the likelyhood of continual failures. Warranties won't be given or the repairs. In your specific case, the switching IC has been damaged and needs to be replaced as well as the surround processing section. This is best handled as an insurance claim for replacement.

One possible reason is the HDCP (copy-prevention)-encoded signal from the DVR, which will transmits through to one device (the receiver) but not to a second (the TV). As an experiment and a possible solution, try reconnecting the HDMI cable from the DVR directly to the TV (provided you have an extra HDMI input on it), and using the component-video or S-video plus either digital or analog audio outputs to connect your DVR to the receiver. If this works, I think that the HDCP is the problem and this is the only solution.
It may be a little inconvenient to remember to switch inputs on the TV as well as the receiver, but you could probably program your remote with a macro to do both. The component video (or, more likely, the S-video) is also the best possible video signal you can use for dubbing to any DVD recorders, if you have one connected to the same receiver. You can still keep the HDMI connected from your PS3 (or other BD/DVD) player to the receiver, and from there to the TV, since that does seem to work -- if you don't mind turning on the receiver every time you want to watch a BD or DVD. My recommendation, however, is to connect all your video signals directly to the TV via HDMI or component, and use the receiver only for audio, or for switching of lower-level video signals like S-video that you can use for dubbing. That way you can always check the DVR or BD or DVD quickly without powering up your receiver, which takes a few seconds and much more power.

Maybe the video portion of your receiver was fried by the lightning. The good news is, you don't need it!
I run all my video sources (sattelite, xbox and dvd player) to my TV with hdmi cables, and a single toslink(optical) from the televison to my 5.1 home theatre receiver. it sounds great and I only use a single input of the receiver for all my video.

If your setup does not have toslink themn use coaxial digital. it is also one wire and probably is indistinguishable in sound quality.

for future, run the power for all your electronics through a UPS or fancy surge supressor to protect them from bad power (and lightning)

Connect the DVD player audio with digital coax into the digital audio connection as you described and the DVD video directly to the TV. Now switch the input mode on the receiver to DVD. Then switch the video output mode on the TV to correspond to the input you plugged into. Any source in 5.1 dolby digital or dts should now work properly and have picture too.

I had to turn on the TV first then the receiver and DVD player to see the video of the DVD.

Firstly, make sure your DVD have built-in IR wireless module so that your headphone can receive the audio signal from your DVD player.

Second, it should be clear which frequency transmitted from your DVD player. Generally speaking, there are two frequency of IR transmitter.One is 2.3MHz/2.8MHz. another is 3.2MHz/3.87MHz. Only emission frequency same as receiver can receive the audio signal.
