Hisense 507D

[wirphotos]

Picked this tv up from a family member. Tv was working fine and then they started having issues. Tv would turn on, show an image and shortly after it would shit down.

I've done some research and did a system reset. The screen comes on and the video is fine in setup. I've had it already where I could watch tv on it for a 30 hour. Other times it will turn on show the splash screen and shut down.

I'm at a lost as it works great after a full reset, but then after a while it goes back to it's old ways.

Help!

Maybe the main board is the same as 55A7,after replacing the new main board of this tv it played well for one day, the following day when I switched on the screen shows no picture but backlight was there on,I cleaned the cables from t-con board to screen thereafter picture came back.
