Turn on TV and picture and sound are great for about 60 seconds. Then the picture disappears but sound remains.


I would start with checking the power supply 12vdc output, make sure it is stable with no ripple. If the power supply checks out fine, I would then suspect the main board.

My HyVision LCD TV Picture disappears after a few seconds


It seems that the "backlight" has gone bad. "Backlight" is the device that allows to see the picture in an LCD TV, when they are about to go bad the symptom that you describe is very usual. It depends on the tv manufacturers and model to expect how long the "backlight" is going to last in a tv.You can shop around for a replacement part and try to do it yourself or take it to an especialized technician. Good luck..
