fresh from reading the comments about "video dropout"on the pioneer 434,I decided to give pioneer a call (I've had this problem since I bought the screen 4 months ago) When I told the guy about my problem,I was told that they're aware about this but theres nothing they can do,and if their engineers ever find out they will let me know .....I was then asked if this was "ok?".............the man was somewhat miffed when my reply was NO!! I explained to him that I wont pay £4000 for a faulty tv just to be told I'll have to live with it,and demanded a new media box........I also explained that I have read bout other peoples problems on AVforums ,and that others have had excellent customer service from them and had received a new box........ His reply to this was that a new box didnt always correct the problem,so theres nothing he can do,or is even willing to do!!! I KID YOU NOT! After spending another 5 mins threatening this guy with court action if he was not willing to even try to honour the 12 month warranty,he said he'll try to get me another box within the next week.I'm not holding out much hope here....... Did any of you had this problem with pioneer?I found their reluctance to even try to help so far truly gobsmacking! I'll keep you informed of whatever happens next........ ps.....sorry if my 1st post here is a whinge,but on the plus side it shows that if you mention avforums,and keep mentioning it,they do take some notice!any advice would be welcome!
