I just set up a Panasonic SA-BX500 amp with several input devices. Two with hdmi and two with RCA cables. The devices connected by RCA cable don't show any picture, but the sound comes through. I've tried changing the RCA cable over with a spare but the problem persists.

To set up your home theater system with the equipment you mentioned, follow these steps:

1. Connect the Onkyo receiver to the NEC TV using an HDMI cable. Make sure the HDMI input on the TV is set to the correct input for the Onkyo receiver.
2. Connect the Panasonic DVD player to the Onkyo receiver using an HDMI cable.
3. Connect the Firestick Lite to the Onkyo receiver using an HDMI cable.
4. Connect the Panasonic speakers to the Onkyo receiver using speaker wires. Make sure you connect the speakers to the correct speaker terminals on the receiver, which are usually labeled with the speaker's position (e.g. front left, front right, center, surround left, surround right).
5. Configure the Onkyo receiver to use the correct input for each device. For example, set the input to "DVD" when you want to watch a movie on the Panasonic DVD player, or set the input to "Firestick" when you want to watch content on the Firestick Lite.
6. Configure the audio settings on the Onkyo receiver to use the correct audio format for your content. For example, if you are watching a movie with Dolby Digital surround sound, make sure the receiver is set to decode Dolby Digital audio.
7. Adjust the volume and other audio settings on the Onkyo receiver as needed to optimize the sound quality.

Once you have completed these steps, you should be able to enjoy surround sound audio from your Panasonic speakers through the Onkyo receiver.

Connecting the audio between the cable box and the TV is easy, if you are using one of the composite or component video inputs. Just plug in the associated R/L audio jacks in a line with the video input. If you are using the HDMI input, that carries sound on the HDMI cable. You don't need to connect the audio out of the cable box to the TC-P50C2. See the connections page of the TV manual here: https://www.manualslib.com/manual/246619/Panasonic-Viera-Tc-P50c2.html?page=12#manual . Then set the TV to this input.

However, the Panasonic TC-P50C2 does not have an analog audio output. You could try connecting the cable box RCA audio out to the Bose Wave system. You will need a RCA M/M to 3.5 mm adapter cable. (Alternatively a RCA M/M to 3.5 mm F converter and an AUX (3.5mm M/M cable or a 3.5mm M to RCA F/F adapter with a standard RCA audio cable will work between the cable box and the Bose ) This may not have the audio sync correctly with the video.

The alternative is to use a digital to analog audio converter and one of the above RCA to 3.5 mm solutions. Get an converter that has an optical digital audio input and an optical audio cable (Toslink). (The cable isn't always sold with the converter.) (https://www.manualslib.com/manual/246619/Panasonic-Viera-Tc-P50c2.html?page=50#manual ) See some converters here: https://www.amazon.com/DA-Converters/b?ie=UTF8&node=3224445011 .

I hope this helps.

SOOOOOOOO simple!
All you need to do is get an HDMI cable, plug one end of the HDMI cable into the HDMI output of the device you want to connect, then plug the other end of the HDMI cable into any of the three HDMI inputs on the back of your set! THAT'S ALL!
Once you have done this, turn on the television and your device, switch the input of your television to the appropriate HDMI input (using your remote control), and VOILA! The HDMI cable carries both picture and sound, so you're DONE!

there is no magic cable fix .
What you most likely need is a hdmi to rca converter
google search mini hdmi2rca
this device seems like the most sold device but there are several posts on its quality

so you need a hdmi cable and a rca cable.
this youtube video rates several of the converters available

The manual...

http://service.us.panasonic.com/OPERMANPDF/SAHT730.PDF

Anything that has a headphone output can be adapted to feed an RCA cable pair for standard stereo to any audio device with a standard RCA input (except PHONO). Get a cable like the one described here: http://www.monoprice.com/products/product.asp?c_id=102&cp_id=10218&cs_id=1021804&p_id=665&seq=1&format=2
and connect it into any available analog input EXCEPT "Phono".

I'm going to assume you mean a cell phone or other device with a headset output...

Hi there
Check your DVD players' settings/manual to ensure the HDMI port is the default output port. Also confirm that both audio and video are enabled on that HDMI channel as it can be separated to be only video or only audio in a lot of cases.
Confirm you are at least getting video out from the DVD with a direct connection to your projector with the HDMI cable.
If video is making it to the projector direct from the DVD, you will need to confirm your amp is monitoring the HDMI input if there isn't a specific input selection for it. Connect your DVD to the amp and your amp to the projector and test again that you are still getting video AT LEAST. This will help narrow down which device is not playing the HDMI game if you still have issues at this point.
To sum up;
Confirm HDMI is the default output from the DVD for both audio and video.
Ensure you are getting video AT LEAST with a direct test to projector.
Confirm your amp is monitoring the HDMI input coming from the DVD.
Hope this helps.

HDMI input connect as follows:

1. Connect an HDMI cable from the Cable box to the TV/CBL HDMI input on the Denon.
2. Connect an HDMI cable from the Xbox to the DVD/HDP input on the Denon.
3. Connect an HDMI cable from the HDMI out-put on the Denon to an input on the Samsung.
You don’t have to use the optical output from these to devices since the HDMI cable allows for the transfer of both audio and video, if you have them extra use them in addition to the HDMI cable and last,

4. On front of denon after you setup and assign your optical connections, if you use them, once you select TV/CBL or DVD/HDP as a source, press the input mode button to select auto

Some where on the back, bottom or sides of your plasma tv you will find input jacks for the audio and video. You must know what type of inputs you want to use.
Most have have 4 types

HDMI (audio and video signal combined)
Component (red, blue, green RCA jacks for video only)
Composite (yellow RCA jack for video only)
S-video ( larger round black jack with video only)

The Panasonic should have all of those also. I am certain it has HDMI and Component.

Connect the HDMI cable into the output HDMI jack from the Panasonic into the HDMI input jack on the TV.

Then using your remote for the TV make sure you select the HDMI input for viewing.

If you use any of the other video outputs on the Panasonic just connect it to the same type of input jack on the TV. Once again check the owners manual for more detailed instruction if you need them.

You must always be sure to have the proper input selected on the TV to be able to view it.

You can also respond back with more questions if you have any.
I am happy to help.
