Neff double oven model u1562?

After reading the imfo on these pages my oven door is not as discribed even the screws are not in the position??
i also have a problem with both the symbol display windows ie as you turn the selector knobs the displays have become disconected to replace these labour and materials will costs over 200 pounds so is it worth spending so much??? could i repair this my self ( may be) as the oven in question is a 1998 model all though immaculate ,thanks vern
