I recently bought a pana TH42PW5B and am having trouble with sound sync, particularly through sky (and more with live tv) although have also noticed some problems with dvd play also. The sound I am routing through sony db780 and kef eggs. On another board it seemed others had the same problems and they are basically impossible to get rid of. The question i don't know the answer to is - is this problem: 1) specific to certain TH42PW5B screenis - i.e. have i got a duff one! 2) specific to all pana screens 3) or a general plasma problem which everyone has to deal with... any help appreciated!!!!
