My mom has a 2000 Philips/Magnavox TV that has perfect sound, no picture except for the following

Upper Right corner:son

Middle of screen: AED 4 L98us1L4

08-3

168 124 255 165 34-2-88

10

Bottom of screen: 12-11-264

the screen is also white in color, the TV was working perfectly before this happened and you have to turn the set on and off by unplugging it as well

Help would be appreciated asap, thanks!!!!
