The on 10/08/2010 bought from me TV LG 26 LE 26 3300 was delivered in the shortest possible time, is stylish and has a good picture. So far so good! Unfortunately, the sound of the instrument is weak and tinny. Trying to connect the TV to an existing, but 15 year old public address system of the brand B + O have so far unfortunately failed. Connecting a wireless TV Kopfphörers does likewise if not because of the sound of the TV is switched off as soon as the Kopfphörerbuchse is plugged into the device. A reception on the Kofpfhörer therefore, (as before to my 20 years old, B + O TV) is no longer possible! What can I do? For advice on how to remedy in advance, many thanks!
