Don't trash it, FIX IT!  If you are capable of taking the back off the TV you are capable of fixing it.  Check out the video description for where I sourced parts for the TV.

When I turn on the tv, the video picture is washed out but threre is a video picture threre and after a few min the video gets stronger and with a good contrasted pix. After about 5 min you have a fine picture and continues on fine. Next time you turn on the same thing happens.
