Turns on but no picture - Samsung PN51E550 51 Inch 3D 1080p 600Hz Smart TV Plasma HDTV Bundle

sony lcd turns on, giving me signal and picture in 2 minutes, then suddenly turns off and the fans goes crazy. what can I do to prevent this? I have tried to reset the projector and switched the powermode to normal, but this didn't help.

Consider having it repaired as it should be in warranty.

most likely the AC in board is causing the issue of the 5 blinks if the lamp has been verified as being good.

Loose contact on the heater of the picture tube

Is it desktop or laptop computer?
If its desktop the data cable might be loose on the back of the desktop computer.
