I have had a HDD7250 for about 10months now and its worked okay,But for the last week it has been making a clicking sound then Starting appears in the display.and my TV picture flickers.Starting stays in the display for about 10seconds,but it will do this every 2mins or so.its getting a bit irritating.it also does it if the TV is switched off.Anyone know why it should suddenly start to do this.Waste of time trying to get in touch with Phillips they don't answer any queries.Thanks.Cumbrian
