It's the 26 inch version but have problem with...

Question

When I first turn on the unit, sometimes the screen stays blank or goes to a ghostly white screen, after a while...about 10-15 minutes the picture will come on or in. Either way, the sound and other functions work well. Channels change, volume controls work, but there is no display to show volume or pic. By the way, this unit was purchased less than 7 months ago.

Thanks in advance,
Paul
