You most likely have a bad main board, seeing as how it powers on. If it wouldn't power on, it would be the power supply board. The boards are easy to change after popping the back panel off of the TV, and they can be found for sale online by searching for the TV make and model.
Be sure to only open up a TV with the unit unplugged from the wall

I have a samsung tx-t2782 with red green and blue pinstripe running horizontal across top of screen. not a ground loop and theres no magnetic interference.


hello spins,
If your problem just pinstripe on top of screen , but picture ok (normal in picture), try it to enter the factory mode. In standby position press info-menu-mute-power. Enter to deflection adjustment- choose - vamp (VA) or v shift (VS). Change value data by pressing + (or right cursor) and - (or left cursor) to shift or increasse amp. If it work, your tv will normal.
But its nor working, you should call samsung technician.
Good luck.

SlimFit HDTV TX-T2782 TV will not turn on


are you outlets functioning properly? if yes and your sure its the tv, then it sounds like the power supply in the unit has gone bad, or it make be fused, which in that case you would just need to reset it or replace the fuse. I would try trouble shooting on your on first, as a repair can sometimes cost as much as the unit

TV won't turn on


Shorted problem. Maybe in primary or secondary power supply. Need a repairman. Busted regulator, or shorted diode.
