Hi all!
So I have an Emerson 39" tv with a model number of: LC391EM3. The problem is the screen will not come on and once plugged in, there is a constant high pitched whine coming from the power board. The area it is coming from is circled in the attached photo.
Once you unplug the flex going to the main board from the power board the whining stops. I am leaning towards a bad PSU board that is not putting enough power out for the main board, but then again I thought I would ask for some input on this as well.
