No Digital TV Picture LG DAT-250 DVD Home Theater with Digital TV Receiver

Start with reading the manual. In some cases, a code has to be entered (depending on the brand/type of the tv,...) to configure your remote. Mostly, there is a step-by-step guide in the manual.
Also, check the packaging/manual of the remote to see which brands the remote is compatible with.

OK. For all you regular Joe's like me here's the fix--plain and simple! I have Dish Networks HD receiver, an LG Home Theater System (LHB953) and an LG HD Television - although I suspect this applies for most LG TV-to-LG Audio Systems used in combination with a HD TV). My problem lied within the LG to LG setting known as SIMPLINK which tries to "auto-configure" everything between LG to LG devices.

Do this to make your HD TV (using Dish/DirecTV) play it's HD video display from the satellite provider but play the audio over the LG surround sound speakers:

1. Plug a HDMI cable from your satelite receiver's set-top-box to your HD TV. This will carry your HD "video" ONLY. Click "Input" on the TV remote until the HD video signal shows your desired TV channel from your satellite provider.

2. Plug an HD Optical cable (the one with the red laser) from your LG HTS (Home Theater System) to your satellite box. This will carry your HD "audio" ONLY.

3. This is the magic everyone seems to be overlooking. On the LG TV remote, go into the menu options and disable SIMPLINK by setting SIMPLINK=OFF. This feature allows the video and audio signals to be split over 2 different ports: HD video goes over the HDMI cable and the audio to go over the HD Optical cable.

Hope this helps!

the HDMI cable sends dato TO the TV, it does not have enuf bandwidth to send both to and from, just TO. 

output on TV cable digital reciever to home theater digital reciever in via an optical cable.lower the volume on the TV cable digital reciever to get the most out of the surround sound system.

Sir avservice, I have also posted a problem about an HT502 DVD receiver + Home Theater. The sound won't come out of the speakers but only of the Plasma tv. But was working before. And the word "PROTECTION" is appearing on the display screen of the dvd receiver. But good quality picture on the plasma tv. Please help

Are you using the HDMI connection on both units, the SC-PT760 does have a HDMI input Yes/NO ? If not then it has HDMI output to the LG for HD Picture. What I would do if no HDMI INPUT to the SC-PT760 is available, run out of the TV with the Digital connection into the SC-PT760 Digital Audio in, assign the input as tv and you shoild get TV audio out of your home theatre, you could also use the analog connection audio out of the tv to the home theatre but this would not yield a dolby digital sound.

Hook a digital optic cable from the Tv's digital ouput to the Recievers digital sound in. This should fix it. You might have to switch the input of the reciever.

Hi try this.

in the dvd player make sure you just leave it default (bitstream) but in the home theater receiver don't select 5.1 b/c that will only give you a virtual 5.1 not a true 5.1. In fact don't select any sound field at all just select dolby digital or dts depending on the source of the movie then you should be ok.

The only other problem i can see is that hdmi sends both the sound and picture to the tv. You will need to see if there's a function on the dvd player to only send the picture via hdmi and the sound via the optical out of the dvd player.

good luck
