Question about Panasonic TH-50PZ750U 50 in. HDTV Plasma Television

1 Answer

Built in speakers no longer work

Checked the TV setup and speakers are enabled. Plug mp3 player directly into all various rca and 1/8" inputs with volume turned up and no sound. I don't even hear the typical "hum" loudness when the volume is pumped up. Nothing smells burnt am I missing something?

    So get this. I used the Panasonic Viera Chat (for support) trying to explain to this "idiot" about the above issue and he keeps saying there's nothing wrong with the TV. I kept telling him, no- you don't understand... I plug a device playing sound that works thru headphone verification and when I'm switched to your input on the TV, I get no sound. Nothing. Your explanation sounds a lot more plausible. Can you tell me if Panasonic corrected this free of charge and at your site? Mine is just out of warranty by a few months (1 year). I haven't called them yet, but I suspect others have had this issue.

We had the same unint in our store with the same problem.
the cause was a manufactior defect.
a heatsink was shorting to a electroletic capasitor on the main audio amp.
fix was to isolate with a non cunductive plastic over the capasitor causing the short.
hop this helps.

Subwoofer channel no longer has output


Is your sub powered (amplifier built-in)? If so, connect your MP3 player directly to the sub input and see if you hear audio. If you do hear audio, check for cable problems from Panasonic to sub input. If the sub is unpowered then it's either the speaker wiring, an intermittent sub and/or your Panasonic at fault.

I have a sb wa340 active subwoofer. I have subwoofer and speakers but I don't have DVD how can I use this


So is the DVD part missing? There is a VCR / Aux input on the back but it is for audio only. There are no video inputs so if the DVD is not included in your sub/speaker system, you'll be limited to audio only. First, you'll need to connect a TV to your system using one 'Video Out' cable methods so you can see the menu for the remote control changes on the system. From here there are 2 options:
  1. Connect up a working DVD player directly to your TV using the best option available. Use the audio outputs on your TV to connect to the VCR or TV input on the system box. (Using standard RCA cables.) You may need to enable the external audio outputs on the TV. (Check the setup -> audio menus etc.)
  2. You can use this as an audio amp by connecting a RCA cord from the a DVD R/L audio outputs to the VCR-Aux input on the amp box. You will need to run a separate video feed from the DVD directly to your TV. (Select the desired input on the TV to watch a DVD.)
You'll need to do a lot of switching back and forth with multiple remotes to get everything working, but the speaker setup can be made useful if it still works.

Here is a manual for the system: http://service.us.panasonic.com/OPERMANPDF/SCMT1.PDF

How do i hook up a rca Rtd325w dvd home theater to a coby tft lcd flatscreen


You can use either the multi pin connector cable, or plug the white, yellow and red cables to the TV set at the DVD player input or "Video 1" and the the audio output of the TV Another red and white set of RCA cables into the audio input of the home theater. This way the TV can play through the home theater system when you are watching cable or over the air.

If you do not want to hear the TV audio, you should go to the audio properties and select "external speaker system" but if you do this the home theater system must be on to hear any audio from the set until you set it back to the TV speakers through the TV's setup menus again.

How can I set up with my lcd Sony tv


If your home theater receiver has a digital optical input, run a digital optical cable from digital optical OUTPUT on TV to digital optical INPUT on receiver. If receiver is older and only has analog inputs, you can get an 1/8 inch to RCA cable(red/white), and plug 1/8 inch side to an output on back of TV and plug RCA side to aux input(or CD or cassette input) on back of receiver. DO NOT PLUG INTO PHONO INPUT! Either one of those cables can be found at Walmart, radio shack, or best buy, etc. Digital Optical cable is definitely the best choice, but I just used the 1/8 to RCA setup to hook up a Sony led to my brother's early 90's Pioneer receiver(not the ideal setup, but will work). Hope this helps.

How can i test my rca output jacks with a test light? pioneer deh p3100ub. hooked up spkr, nothing. tried one rca plug to white(lt) and then red(rt). Unit has 4 rca jacks, 2 for subwfr and 2 for front...


:) the rca jacks have to be connected to an amplifier,, their signal is too lay to even light a bulb.. you have to connect it to a car amplifier and then from the amplifier to the speakers..

Just so you'd know,, once your deck plays and you hear music on your speakers through your normal speaker wires,, RCA jacks work..

Ok you have 4 jacks,, 2 subs and 2 front.. These should connect to a preamp,, which takes 4 inputs and allows you to equalize or adjust how the music should sound,, now from the pre-amp,, it runs to an amplifier,, thats powers the subs and another that powers the speakers.. Some amps have 4 inputs so you can use one amp for your subs mids and heights..

for example a basic music system is

1 cd player
1 pre amp
1 amplifier (4 inputs, 4 channel out)

you bridge 1+2 and connect this to 1 12" double coil sub woofer

the next 2 connect to 2 mid speakers example "rockford or ev 5 / 8 " and 2 tweeters for heights..

Thats a kicking tricked out basic car audio system,,,

Hope that helps you understand how it works..

Can't get signal from drc6309 to video/audio input


I dont have a Solution but I have the same problem with my RCA portable dvd DRC6309. I have connected it to three different tv set and I get no Video but I do get Sound through the tv sets... I have sent an e-mail to RCA costemer support hoping for a solution. If I hear anything back I will post it here...

I bought my RCA DRC6309 about a month or two ago at a Wal-mart supercenter. They no longer sell RCA portable dvd players. That is why I contacted RCA directly.

TV Audio out to HRT 5650 receiver


You may need to enable the fixed audio output line level from the TV. Some TV`s require you to enter the AUDIO menu/setup selection on the TV remote controller, and then enable the AUDIO OUTPUT Jacks, this will turn off the TV built in speakers and engage the audio RCA Jacks.

Audio output from my TV


take a red and white audio rca cable and cut off one end of the jacks. on the end you cut, solder a headphone output plug on. can also solder on the lines of a pair of headphones (where you've cut off the 1/8 in jack) directly to the rcv jacks.

No Picture from Component Input #1 or #2 but do have audio via Surrond Sound


Simplest thing would be that your component cables are not HU'd correctly. Having them reversed would do this.
