Sounds like the backlight is out, can you see a picture when shining a flashlight on the screen. if yes you have either a bad inverter power supply or bad screen (panel).
both are serious , also could be just a few bad capacitors on the power supply, if you want you can do a visual of the power board caps will appear swolled on top and are easy to solder in cost about $1 EACH

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


Hi Paul,
It looks like your TV might have a main board failure if the screen stays white without video. Since your TV is less then a year, I would suggest to contact the manufacturers to get fix under warranty. Most electronics devices carry one year warranty.
Good Luck.

NO VIDEO


I have a Samsung 50" plasma, that has been blacking out over the last 6 months. A 9/2005 set. Now its practically unwatchable as it happens 3 times in an hour. Its not heat related - I have a high volume 9" fan activated on TV power on. Turning the set offf/on usually makes it come back for a now short while. Considering to go put it in the back of my pickup and park it in front of Best Buy and discourage Samsung purchases. This is the 2nd Samsung TV I've purchased (the other a 32" tube) I gave to my folks a couple years ago and its gone bad as well. Samsung product may look good, but their video engineers are not.
