Question about LG LHT854 Theater System

I keep losing my picture

I have the lg lht854 home theater system and a toshiba 40' lcd television. when i watch a movie about halfway through this black line appears on the right side of the screen and the picture cuts out on the screen for a couple secons and comes back but it does this throughout the movie. i have already tried different hdmi cords and different hdmi ports on the t.v. and it still did it so i assumed it was the hdmi output on the unit and exchanged it for a new one. it worked for about three days and recently started doing it again is there something im doing wrong.

    I have the same, I will watch a DVD and get a white flash on the screen or the TV will lose its connectivity to the TV and then come back.  Or i'll get pixelated lines on the picture while watching.  I have changed the HDMI cables twice and am not sure why this is happening.  Help.

    i have an LG 32' 720p TV and LG LHT854 home theater and it wont hold a picture either. i dont think its the HDMI cable, output,or input cause it works just fine through the HDMI set at 480p but i keep losing the picture when i set it to 720p.

This is what you call a simple defect, the manufacturer released a product that wasn't ready and knew it. The problem that you are having is a variation of various problems due to a faulty play back device that is located internally and you will have to send it back to the manufacture for repair. Most product that are first through fifth generation are just naturally going to have issues, the releasing company intended on this, and just got paid by you, to have you do the trouble shooting for them and in detail may I add. Just don't let them charge you for the repair.

I don't know how to hook up my LG lht854 to my time warner cable box so that it plays the tv audio. please help

Treat the Cable Box like any other audio device.

IF the cable Box has optical digital output, run it to the LG. Run the analog audio output of the Cable Box to the TV so you can watch lo-fi shows without the LG turned on.

The best Cable Box Video should go directly to the TV.

Black screen flashes up on screen

Turn off the auto setting on the resolution. Either keep the dvd set to 480i or 1080p or whatever is the highest resolution your tv supports.

The issue might be that you have to send the LHT854 Back to the manufacturers and have the playback feature replaced. The playback feature is controlled by a device that is internal and very important to the overall function of the unit.
