TV Hisense lcd40v86p

Hisense lcd40v86p 40 inch TV. The problem is in the screen power supply system. Needs replacement. The screen (matrix) itself is intact; fully operational. Nothing is broken or cracked. The TV switches channels; the sound is completely clear. There is no original TV stand (legs); We used a wall bracket. The bolts for the wall are all there. Everything is included in the TV.
