After i send my first old box back to seller and he couldn`t repair it, i got a D8444. think, its a nice box, sounds ok, but.... it needs to be cleaned. especially the speaker grills, who look dusty and dirty. how do i remove them ? are they just stucked in, are they glued, or do i need to open the case ? i just want to get the grill a shower and cleaning....

ok, downloaded a service manual. think, i`ll check it this evening... thanks .
