No power?
Unplug power cord- safety first!
open backcover
check powersupply- top center right is p.s.
top left side of powersupply you'll see 5 capacitor 3300uF 10V.
see any pop up on top? replace it All with same rate or 16v is O.K.
do not use temperature rate 75c. Use 105C.
if you know how to solder. you could save $300 at least!

No sound on lg tv when connect dvd player through hdmi


I have the same problem. Good picture with no sound at all. I have a LG DVX583KH and LG TV LM7200. I connected the DVD player to TV via HDMI cable, I have a clear picture but no sound. I try to hook up the DVD to other TV and it works both sound and picture. Please help

I have a 55" LG


Easy solution; this is a very common problem. Connect Cable or satellite box / DVR directly to one of the TV HDMI inputs. Connect an optical audio cable from that box to receiver so sound is surround through your speakers. You cannot connect DVR directly to receiver because the anti pirating chip will shut off the picture and produce a green or no screen at all.
You can, however, connect a BD (Blu-Ray) player via HDMI cable directly to your receiver without that problem. Connect HDMI output from receiver to a second HDMI input on the LG.
Contact me if you need more help! All the best, John

How do i use it so my tv programming is in surround sound?


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.

LG 42LG5 hdmi not working


Have you tried another HDMI cable? The cable may be bad. However, if this is not the case and this is happening across mutliple devices(cable box, dvd player, etc) then you might have a bad HDMI input on your TV. Does this happen on all HDMI inputs on your TV? If you can safely rule out your other devices and the cable itself then you've got a main board problem and would need to get it replaced.

anytime you connect componet signal (green red and blue)to regular video inputs (yellow) end will have same effect. make sure that if you are using component signal from source(cable box,dvd player etc) you have to connected to component input in the set.
component signal will use green red and blue for video and red and white for sound.

Cabling -- Panasonic LCD TV into LG DVD player (model no. DV6812P)


Take the basic Red, White, Yellow component cable -- plug it into the backside of the DVD player and plug the other side into the back of the t.v. Make sure to plug the right colors into the right sockets. If there are no available AV inputs on the back of the t.v, plug the other end into your cable box (if you have one).

Audi but no picture when cable box conected through DAV-X1


It won't work as the DAv can only output to HDMI by bringing singal into the HDMI input.

why wouldn't you send it directly to the TV and Audio to the DAV? I sounds like you don't have an HD box anyway (otherwise why would you use an analogue S-video cable vs component or HDMI). Unless there is a distance issue then go to the TV.
