Bought one of these for the bedroom, made the mistake of buying it from Dixons....Got it home only to find there is no manual in the box and typically the store was closed by the time I found out..... I've managed to sus out most of the controls, but is there any way to reassign the tv channels? It autotuned but everything is out of order and I can't find a way to manually tune it... Help! Other than that, initial picture impressions seem good and Dixons have it reduced to £499 at the moment. Thanks in advance.
