Question about Televison & Video

Open Question

I am trying to connect NEC Plasmasync 4210W with LG HB905SA Blue-Ray home theatre system through RGB cable and I am getting only noise on screen. When connected only with 1 cable, as supplied in the LG package, I do get picture but black-and-white and poor quality. The sound from the settop box (TV) is connected to LG Blue-Ray through the AUX In in the LG box, and works. I need picture from Blue-Ray on screen! Any help! Thanks. in advance.

If you're NOT still under warrantee you should at least open the TV and check the board where the components are mounted and resoled any that look bad. If you are using a surge protector, try connecting the set directly to the wall outlet. In your case it could caused by a blown fuse, a leaky diodes or a bad solder joint at the horizontal drive transformer. All can be replaced at a local electronic or hardware store and they're easy to replace If this does not correct the problem, you may need to have your TV serviced. good luck!

SOURCE: samsung lcd ln46a550pf3 no sound from hdtv reciever

ok your tv does not come with the very best sound, you have to get a receiver 7.1 or you can use the optical wire , that's if the system you are using has that option.

SOURCE: No sound from plasma to home theatre

First off it's always best to start from scratch when it comes to home audio. LoL. Many times I've been in this situation.
So with everything disconnected. You should have your HDMI, COMPONENT, RCA(R,W,Y)
HDMI and COMPONENT are the exact same thing and in all preference COMPONENT is far better thand HDMI for the pure fact that each wire is in it's own casing and insualted to avoid feedback from the other wires.
Anyways, with everything disconnected we begin
From you Cable/satellite box- Run your HDMI cable from you cable box to your HDMI 1 input on your tv.(If your speakers were to work on your tv you would automaticaly get sound and picture)
That should be all that you should be running from you cable box. Now that we have one thing running we go to the next thing.
From your TV run your audio out (RCA Red/White) to your amp. Usually your preference but more than likely your TV IN on your amp.
With your amp now set on TV, you should automatically get sound from your tv. and if your running an HD cable box even though your only running RED/WHITE to your amp, you will still be receiving Digital sound.
Most new amps Should have a digital input and if your running and 1080iUp this one RCA plugin will give you dolby digital sound from your dvd player to your amp. Then running a video rca up to your tv, will give you the picture, while the digital out on your dvd player to your amp will give you dolby digital sound.

It's a basic simple step to get sound. Like a continuing current. So just as long as you have your cable to -- tv -- home theatre. Everything should work. Otherwise I would go and check your cables and make sure they are not faulty.
I hope this confusing walkthrough helps.

I have bouight a samsung home theatre system that comes complete wiht a DVd player - i also have a samsung blu ray player - naturally ithought they would be compatible!! how wrong i was!! the connections...


You have several ways to do this. You can hdmi cables from the two units and plug them into your tv if it supports hdmi and run the audio out portion on the back of the tv and hook that into one of the audion inputs on the surround unit. Or you run audio directly out of the bluray using rca, digital coax, or digital optical cable. Turn the surround reciever to the corresponding input that you choose to use.

Ghosting of picture from a Panasonic home cinema system


There must be a fault in the screening of the internal wiring to the scart outlet in the home theatre system. I simply changed the way the player was connected to the TV and the interference disappeared:-

1.) I used the RCA video outlet instead of the scart lead. Picture quality was not compromised. FYI the Panasonic Plasma TV I have has only RGB video input sockets at the back, so I used a scart to RCA adaptor to overcome this problem of connecting old technology to new.

2.) The surround sound when playing DVDs is generated directly from the home theatre system so there was no need to connect the audio from the home theatre system to the TV

3.) I used a pair of RCA leads to connect the "audio out" from the TV to the "audio in"on the home theatre system to provide the option of TV sound through the home theatre system.

I have no surround sound when watching normal T.V


Hi there, in order to listen to t.v you need to purchase an optical cable and plug this in the optical out of the tv to the optical in on the blue ray then select D.IN.1 on the blue ray and press mode on the remote until it says matrix . This will allow you to listen to the t.v through all speakers. hope this helps. Also remember to take the rubber protectors off the ends of the optical cable, a lot of people forget this :)
