[QUOTE="nadal liu, post: 927774, member: 401837"] I made an experiment on the stb hooked up to 5x20. 5x20 doesn't have external power provider to lnb. I turned on one of my non-japanese stb that send 13v/18v on 124E on horizontal channel. Leave it there. On the second stb, which is japanese stb, I checked that both horizontal and vertical channels are there viewable. That concludes my theory: multi-switch doesn't always send signal from its own power, it pass the current from stb and pass it over to lnbs. In my case, because my regular non-japanese stb sends 18v to multiswitch, the current is passed on to lnb. When 124E and H is watching on stb 1 that sends 18v to multiswitch and multiswitch pass on to stb. On stb 2, the horizontal signal is ok, because lnb already is powered by stb 1 and the electric current from stb 2 is not send to stb to avoid problem. If my theory is correct, then a external power adapter to lnb will solve my problem. Just a wild guess. Please advise if it is correct. Thanks. [/QUOTE]
