Grundig Vision 2 22-2830 T

Leave well alone. I now have a second, the first when playing DVD film occasionally the film would stick for a few moments then continue to play. When playing a music CD every so often a buzz would sound. Play the same items on other equipment, no problem. The brightness and contrast settings have to be at maximum to watch TV or DVD. The store changed my set when they had a new delivery. The second TV only had two days and is the same. Ishall leave it a few days then if no better return the set.
