try audio out jack on tv.... you will need an amp however to power your speakers

A standard toslink optical cable should fit.

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on; or it may turn on but produce no audio to the speakers.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'nekkid'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

That cable doesn't exist. You can't just shoot electrons into one end of a copper cable and have light come out the other end.

My $.02...

Treat your TV like the primary user of the Hi-Def Video ONLY, not the source of any audio. Ask yourself, does it really NEED to be in an audio chain if it doesn't tune the station off the air?

Your JVC should be the primary destination of high-end audio, directly from, say, the Cable Box' while the Hi-Def video is sent to the TV.

Zigzagging good audio and video through the room to devices that don't need it is expensive and wasteful, plus it adds complexity and unnecessary connections that add nothing but could fail.

Can you connect external speakers via a stereo jack plug rather than the HDMI interconnect to see if there is any sound anywhere other wise it might be the output thyristors then have blown.

This depends on the extend of the damage.If the board is carefully analysed and if you can sort out the damaged parts take a reading. Check the ouputs that have failed, check into the next stage below till you come to see that all the componets that were burned were identified. If you are able to idetify the value of the burned components, there is no issue but if not we have a real issue.in this case you must seek help with a servicea manual .If only thepoweer transistors/ resistors have blown you can go for the replacement provided you feel confident to go along after the components are replaced.In the first place I never asked how this had happened. was it overloading or otherwise? hope I could Help. Good day.

on the back of the TV you will find a set of RCA connectors marked "VARIABLE AUDIO OUT" connect this output to the sound system audio in.

is a programed microprocessor (microcontroler) , only the jvc has correct version.

the reason that you cannot see the wii is because the yellow connection on back of th-d50 is an output not an input. you will need to connect the yellow to your tvs input if possible, and leave the red and 9hite for audion on th-d50. if wires are attached together, then you will need to connect your wii directly to tv, and then use a set of red and white cables to connect from audio outt on tv to audio in on jvc unit.

you will need to connenct audio cables red and white from audio out on tv or from programming source(cable box sat box) to the audio in on back of jvc unit. then set unit to appropiate source (where you connect cables on back of unit it will be labaled and remote will have button to get to that connection labeled the same) if you want to get digital sound you will need and digital coaxial or fiber optical cable from source(cable box or sat box) and then set unit to video 1 for coaxial and video 2 for optical

you can purchase this items thru phone calling jvc directly 1-800-252-5722 or on there website jvc.com. the remote will cost $27.01 and the manual $6.18 plus tax and shipping. you can pay with visa or mastercard. if you hear sound thru 2 speakers there's a surround button on remote that can get the rest of speakers working. or you will need to check speaker connection and set unit to right surround setting by pressing surround button.

you press and hold + button and eject button on front of unit . you will message "unlock" in front of unit.

yes its posibble. you need to use a 3.5 mini plug(like your regular headphone connection) to red and white composite(male plugs) cable to connect to back of th-d50.

I my self don't have that exact unit, but most are similar, and i have looked up the specifications which are:

Inputs:
1 x S-video input
1 x Composite Video Inputs
1 x Digital Audio (TOSLINK) Input
1 x Stereo Audio Input

Outputs:


document.write(neg_specification_newline('1 x S-Video Output1 x HDMI Output')1 x S-Video Output
1 x HDMI Output
INPUTS (coming from devices to the system):
1) The unit already comes with a DVD player, correct? If so you don't need to connect it. If you do, connect your DVD play via an s-video input, since a normal DVD player doesn't need a higher quality/resolution input.

2) Connect your cable box to the home theater system via a composite cable (the one with Red green blue), if it has composite outputs ofcourse. If not, do it visa versa with the DVD, if your dvd has composite. So make the dvd via composite and cable box via s-video.

3) Audio from the dvd, this would be via Digital Audio (TOSLINK) Input or stereo audio input. the digial audio will give you true 5.1 surround sound, and the stereo will only give you left and right channels, like you would hear from anything else (like a normal cd, radio, etc).

4) audio from cable box, would be again depending what you want. If you cable provider gives you alot of programming that has 5.1 surround sound (mostly HD channels), you would be better off with the digital audio. But if you watch more via your DVD, then connect the cable box via the stereo input. Again, this is to your preference, and which one you want true 5.1 surround sound from. The system should be able to 'emulate' 5.1 surround sound via the stereo cable too, but if your watching a movie, it can't really tell if a sound is supposed to come from the left rear or the left front.

Output:
5)connect to tv via HDMI if available, or S-video.

HDMI is much higher resolution (HD quality) S-video is normal cable programing or 'dvd quality'.

And the Tv would be left on mute or volume=0 since no audio is connected to the tv! All the audio should now come from your system.

Sorry if this was too vauge, but I don't have the same system and dont know exactly what/where all the connections are. If you have any other questions let me know.

have you used a different connector cable?

if not try that first

It is usually as simple as getting a 3.5mm stereo headphone jack to RCA adapter, like this one:
http://www.radioshack.com/product/index.jsp?productId=3359117 (this will work just fine, even though it says 'ipod')

Or they have "Zune Ready" adapter kits, like this one:
http://www.radioshack.com/product/index.jsp?productId=3004031

Once you have the cable, you stick the headphone plug (3.5 mm stereo mini-phono) into the headphone jack on your Zune, then you insert the red and white RCA jacks into an open input on your surround receiver... most have an auxilliary input jack set on the front of the unit. All you need to do at this point is select the "aux input" for the source on the surround receiver, start your Zune, and make sure the volume on the Zune is somewhere in the 50 - 75% range, and you should be good to go.
