Got a Phillips 9617 and despite the peculiar geometry and its tendency to bend the pic when the screen is bright, it's worth it for Pixel Plus! An exceptional picture! But...... I have an annoying BUZZING noise coming from the back of the set. Not a hum, or slight whistle - those we're all used to and expect. This is a Buzz. Now an engineer visited and said that this is perfectly normal. Something to do with cbles or wiring around the tube. Now is that the case? Other Phillips sets I've looked at in stores don't buzz like this. Is there anything that can be done? Any engineers out there who can help?
