Question about Philips 9P5544C 55" Rear Projection Television
55" Phillips-Magnavox rear screen. Chassis PTV840. When the TV is powerd on, you get a expanding white raster with horizontal lines and then the screen blacks out after a couple seconds. The power LED remains on (green). No on-screen menu or other controls.
This denotes a problem called blooming the horizontal lines you see are called retrace lines this is caused by the increase in anode voltage which could be caused by an increase in HV section current which trips the overcurrent protection dircuit and turns the TV off.If you do not have electronics experience I would suggest taking the set to a TV repair shop.
