ok..robin guess it may be an IC chip problem..so it's going back to japan for replacement or repair...hope to see it in a week or so!!!
hoho! and i've just DIYed a powertank! cause feeling a bit bored..dual independent switched RCA outputs, 2 x 7Ah redundant power supply (battery can change to any amp-hour as you wish) and modded all the power cables to gold plated phono plugs! can't wait to get back my starbook and try everything out!!!!
