Philips replaced my broken 170B TFT screen by a superior 170B4 TFT screen. It even features a mic and loudspeakers I didn’t have before :)
The replacement process wasn’t straightforward (first, they sent me a 170B TFT that had another defect ;). Nevertheless they were keen to offer good customer service (3 year on-site warranty is extra-ordinary. And they were quick too!). Will buy Philips again.
