I have a sky+ hd box connected to an lg 42LH300 tv through hdmi and an LG HT805SH home cinema through optical cable. Whenever i turn sky over i lose sound and have to turn cinema on/off to sound returns HOME CINEMA IS ALSO CONNECTED TO TV THROUGH HDMI. What is correct set up please. Thankyou

Your sky HD may have to output one is HDMI that will go to your receiver the other is component you can run that to your television and you still will get a decent picture at 7:20 P

No there is no way to replace it not unless you have it repaired by a LG Authorized Dealer/Store.

Hello,
There are two things that I can suggest.
1-Test your optical cables to make sure they a good on a known working source because they are very fragile and break very easily.
2-Try to eliminate the use of optical output from tv to receiver. There may be a problem from the HDMI to optical conversion at the tv. Instead, try running the audio directly from the source to the receiver, and let the tv deal with video input only.
Hope this helps,
Good Luck.

Hi,

Not sure what you mean by "optical connection" but you need to connect your SkyHD box to your TV using both HDMI and SCART cables. Your Sky HD box will then send the signal via the HDMI cable for the HD channels and the SCART cable for the SD channels.

Hope this helps

This TV has no HDMI input socket. It Has a DVI input socket. Therefore you will require an HDMI to DVI converter adapter or an HDMI to DVI cable. The DVI is video only so you will require audio cables from your Sky box (Audio L and R ) which will connect to the back left of your TV (Audio L/R sockets next to the s-video and component video connectors)

if the Comcast cable box has an HDMI output, it should connect directly to one of the TV HDMI inputs. Then connect the LG DVD unit HDMI output to the second HDMI input of the TV. Use two HDMI cables. Do not buy the expensive Monster HDMI cables. If you have already done so, I recommend you take it back for a refund, then buy the low cost HDMI cables which will work just as good and then you can bank the savings toward a new Porsche Boxter!! Now we have the video connected from both the cable box and the LG system.

Now--what do you do if the cable box does not have an HDMI output--just use its component output and your component cable (red, blue and green) to connect to the TV component input. This will still get the video to the TV and good HD pictures. Hum--do you have an HD cable box? You did not say and I just assumed that you did since you got the HDTV. If not, let me know with a follow up question and I will assist in that area further.

Now for the audio connections--The DVD player will not need any connections since it in the LG unit. The sound will come out the speakers when you start playing the DVD. The cable box is where we get the TV audio to feed the LG unit. If the cable box has an optical output, use an optical cable (again the low cost one)and connect to the optical input on the LG.
This will get the TV audio to the surround system. If no optical output, use the red and white (left/right) audio connections and connect to one of the two the LG audio inputs. To hear TV audio on the LG speakers, just switch to that input or the input associated with the optical input.

To watch DVDs, switch the TV to the HDMI input to which you connected the LG unit. For TV, go to the other HDMI input (or component input).
Switch the LG to the audio input to which you connected the cable box to get TV sound.

Hope this gives you food for thought. If so, and you have more questions, just come back in with a follow up.

you need a Optical audio cable, run this from the back of your Sky HD box to the Surround sound. Not all Broadcast are transmitted in DD so press your i button on the sky remote and you will see this on the yellow bar above the program information if it is..

Might be worth running a set of White and Red audio cable from the HD box to the Surround sound as well that way you can just mute your telly and have the lot coming through the surround sound system.

Hope this clears things up for you

link your optical cable from your HD box to your surround sound.
Then if you go into your HD services menu, press 4 then go to sound make sure its set to Dobly D
That should sort your problem out

do have sound and picture at same time you will need a fibre optical cable, you connect that from your cinema system to your tv. then you need to set your cinema system to digital input or fibre optic or check by pressing aux on your remote and see which is the right one. i am not familier with panasonic as i have samasung.

You need to be connecting the TV and the Sky Plus to the HT box via optical (toslink) for full surround sound. As you only have one optical port on the HT, I would suggest buying a Optical selector such as this one. I would also suggest looking on avforums more more help. I use it for most of my questions if ever i need any help.

Hope this helps!
