Had my 32pw9617 installed for two days now. Picture looks very good (to me) and the sound is excellent. However .... two possible problems - looking for advice before I call the shop and arrange for it to be changed - maybe it can be even better. I've set the picture up using some of the info in other posts from this forum but then I decided to have a go with the THX setup (as on Terminator 2, Monsters Inc DVD's). First problem. On the video setup, the first test set's the contrast using a square with 4 shades of white. On mine, if I just leave the test running, don't touch anything (menus etc) then after about one minute the left hand side of the square develops a dirty green tinge (that gets stronger over time) and the right hand side goes amber. Reasonably weak but definitely there. Second problem. On the audio setup, I get no sound from the sub-woofer. That's not right is it??! Any feedback appreciated.
