I have a 32" Philips Magnavox (TS3258 C101), Chassis Model 32D700-7570, Manufactured March 1999

I have been using this for last 10 years, and it stopped working suddenly.

When I turn on the TV (remote or front button). I get great sound and the color looks great on the bottom half of the screen. There is nothing on the top half of the screen it is completely blank and void.

Any suggestions on what I can do to fix it...
