My Onkyo fixes the lipsync issue nicely. But I am fed up with LG. I've put in a complaint with the ACCC and they have accepted my claim and will start an investigation. I've also notified my solicitor and gotten his firm involved. Hopefully I get my full refund. You should do the same I reckon.
Please let me know if there is any way I can link up with you regarding the ACCC. Solicitors worry me as they tend to charge highly for there work. How much did you pay for your tv,, I paid $14000 including a full replacement 5 year warranty.
Maybe a joint complaint would be more effective ?
Do you have any issues with the Banding which on mine is noticeable and definitely irritating when light pictures - sky etc etc.
