Hi, If any of you 9527 owners are suffering with black bars and havent contacted their retailer about it. Then please do so now. Ive just been on the phone to Philips"Customer care" to discuss my black bars. Apparently it isnt an issue with them. They didnt know what I was talking about. Theres me thinking that they were aware of the problem, when in fact they are totally oblivious. I tried getting through to tech. dep, not a chance m8. You need to know the secret code to talk to them. So I said to the lady at CC would Philips be aware of the problem if they were flooded with calls from P****d off owners? She said yes..... So basically to make them AWARE of the problem they have to be pestered a lot it seems.Then maybe they will do something about it. So get ringing!!! btw I mentioned the ferrite rings to my service engineer who contacted Philips as well. guess what he didnt get anywhere either.
