I was impressed in the beginning with my purchase of the Sanyo 28WN5H2, but within a few weeks the sound began to become distorted. We returned it to where it was purchased and were told that it did not have a warranty because it came from a retail warehouse and it was not their policy to issue them!!!!
Have paid to have it looked at and was told that the sound mechanism was of very poor quality!! My sister bought an identical TV from a large chainstore and has had the same problems.
SANYO need to get this sorted out.
