Try unplugging your TV for about 10 minutes and also hold the power button on the TV for about one minute and then plug your TV back in again and turn it on to see if the white screen is still showing up again. It could be the capacitors inside of the TV have gone bad or the powerboard is not working.Check the cables and the connections to your TV to make sure they are fully connected. Or the TV connections are bad and should be replaced.
Question edited for full 'make model (what it is)'.
Question moved to Sanyo.
Could be the power supply, it could be the main board. My advice regarding home television repair, unless our Television Expert Larry comes along.

Hi,\015\012\015\012I'm sorry to hear that.\015\012\015\012This is a common fault on cassette decks and can be caused by a number of things.\015\012\015\012The most common is the motor being seized or worn.\015\012\015\012If the motor spins when you touch the belt then the problem lies in the drive mechanisms.\015\012\015\012There is a good chance that the drive belt has perished and needs to be replaced.\015\012\015\012If the deck is drawing too much current when you switch it on the fuse will blow.\015\012\015\012If the fuse is fine and the deck runs for a few seconds before cutting out then the problem could be one of the capacitors in the power supply.\015\012\015\012If the deck is more than 10 years old then it may be time to replace the capacitors.\015\012\015\012You can do this yourself if you are a little bit handy with a soldering iron.\015\012\015\012That's about it really.\015\012\015\012
Hi,
it's sounds like a group of the screens leds have overheated and/or burned out. If you just got the tv, this would be strange. However if you've owned it for years, then this might happen. Please attempt one power cycle and then flip through channels to see if the issue remains.
If so, you might need to set a tv diagnostic-appointment with a company like geeksquad/ home depot after attempting a factory reset on the tv.
Thank you.
Hi,
Please adjust your tv's contrast and brightness to try an overcome the issue. If there are accessories linked to your tv, please temporarily remove those accessories and restart your tv to see if the issue goes away.
If all else fails, a factory reset would be the next option.
Thank you.
