Question about Samsung LE40R74BDX 40 in. LCD Television
Samsung LE40R74BDx . After about ten minutes the picture goes blank but the sound is ok. The tv is about 3 years old
If you still have the tv, remove the power board and look at the transformer connections. one will be burnt, due to poor quality. check this video, http://www.youtube.com/watch?v=XdsDxKkcesg

It sounds like the main board may have went on the TV. It should be not that costly to replace
