I have a Loewe Aventos that is unable to produce satisfactory black and white images. Below, I outline the history of this problem. · Purchased Loewe Aventos. Yellow and blue areas appear in black and white images (both broadcast and DVD/VHS playback, but particularly noticeable in DVD playback of high contrast images). · The discolouration occurs in the upper area of the screen with white background. · The tube was replaced on the assumption that it was faulty. This made no difference. The whole set was replaced, but still there has been no improvement in the picture. · I have tried different DVD players through the Aventos, removed the aerial, reduced the colour setting - but still the discolouration remains. The DVDs play perfectly though my DVD player on three other televisions (none of them Loewe). · Worryingly, I have noticed this problem in colour images too where there exists high contrast between the light and dark areas of the screen. I am currently attempting to address the problem with my retailer and Loewe, but would be interested to know if anyone else has experienced this problem and has any suggestions.
