I have a Samsung LNT4071F TV that begins displaying green tinted

Customer Question

I have a Samsung LNT4071F TV that begins displaying green tinted interference or noise after being on for a short time. Eventually clears then returns to poor picture again. Now, along with that, the picture is upside down all the time. Can't use TV for anything for several years now, just gave up and bought a new TV. Still would like to know if this one can be fixed. TV can't have more than 25 hours of use, as the problem occurred soon after I purchased it in Feb. 2008. I procrastinated since I do not watch TV too often. Should have been a warranty issue.

OK, TV symptoms indicating failing capacitors on power supply board which caused unstable/ low voltage supplies to other circuit boards in TV and resulted poor quality picture, it also cased delayed power up issue. Please check the power supply board for swollen/ bulged or leaky capacitors and replace them with same rating or swap the entire power supply board which will help to resolve the problem of delayed power On and pixeld image.It would also need to go into TV service menu to find out an option to flip the picture to get it normal on screen. I trust my input will help you out.
