Hi
Thanks for using FixYa. From what
you have described it seems the issue is with the power board or the main board
we’ll need to check few things. When you open the unit up; take a look at the
power board-the board where, the power cords/plugs goes into. You might see
some filter capacitors a little bulged up in the top-If this is the case-this
is your defective part(you can try to replace them-but some soldering equipment
is needed). If not, then probably the main board has gone bad. This is the other
board-where all he inputs are going into. Also check for the Backlight Inverter
Board if the sound is coming fine from the TV however as its shutting off so it
should be either the power board or the main board. All this is only
recommended if you have electrical expertise and know how to solder/re-solder
components. . Please do accept the solution if
the issue is resolved or else revert for further assistance.
Thanks
