I purchased this product 1and 1/2 year back, and it was working fine till 2 months back.
Now it is flickring when connected to Progressive scan DVD player for initial 2 minutes and then become stable.
I am not sure what makes it flicker in the start and then becomes alright, I tested it with other brands of DVD player also, same problem.Looks like after it heats up it starts working normally
I hope it does not degrade with time as it started 2 months back.
It even works pretty well with PS2 gaming on progressive scan after warming up
It works pefectly fine with normal RCA connection and Cable connection and no degradation in Sound Quality.
Other wise this product is good value for money and gives good picture quality, as this is a 100 HZ, this is soothing to watch TV on this.
I hope philips revert back on this and let me know about the possible causes and solutions
