Sound problem with LG LHT754 theater system

All of a sudden the dvd player system stopped playing the sound out thespeakers that came with the unit. I can still watch a dvd fine andsound will come out of the tv (samsung slimfit) but nothing will comeout of the speakers. The sound problem also occurs when I put a cd inthe player as well and the tuner which used to pick up radio channelsdoes nothing as well. I have not changed any of the settings on theplayer, and I have checked all of the connections to the speakers, hdmicable and they are fine. I am at a lose. This unit is only 7 monthsold. Any suggestions would be greatly appreciated.

    no sound 5 months old local tv repair shop says main processor chip has failed and can not locate replacement

    Had the system just over a year - we don't use it very much. Sound system won't work and we can go to anything but DVD (no AUX or iPOD). This is **** - LG needs to step up and put a recall on the issue.

Hold down "2" on the remote simultaneous to "stop" on the receiver. In a couple of seconds you will see something appear on the display. OPO-63? Anyway, repeat the process again when you see that. The system will reset. This will also take care of the inability to switch to AUX or Ipod.

    This really works. Thank you


I have the same problem. Happened after 4 months. LG talked me thru factory reset with no help. Of course labor warranty is only good for 90 days, so I'm out $70 bucks plus shipping to have it repaired.

The motor that spins the disk has failed - the cd unit is dead and the unit is no longer listed in Computer because of that. Just replace it with a new one - it's a very cheap part, less than $30.

Yes I would replace it, the laser pickup assembly is showing early signs of failure, it will often play the regular dvd movies because there is less demand on the laser tracking system. The cost to replace is cheaper than repairing the unit.

I have the same A/V receiver and in my setup there is an audio output (red and white able) coming from DVD player directly into Zenith Z763B. The video from DVD Player goes to TV input (yellow cable).
There might be alternatives to the setup mentioned above but I like to watch movie in a surround sound, rather than output from TV.

Suddenly "cannot play this disk" on Sony DVD/CD..every DVD...CD's work!

I have the same problem. I have a 5 year warranty from the company I purchased the unit from. I am not sure if they will replace it or not. I am reluctant to buy another one with this known issue. We have enjoyed the unit for nearly 3 years with no issues.

Picture sticks, breaks up repeatedly

Change the location of the unit, this sounds like an overheating problem. It is too close to other units or is enclosed in a tight space. You may also try putting a small fan behind it to cool it down.
