I have a 2010 46 inch Sanyo LCD TV, model number DP46849 that shuts off just a couple seconds after I turn it on and will not let me turn it back on for about 20 more seconds then stays on for 2 seconds and back of again, this is all it will do, should I junk it or can I fix it or would it be best to leave it to the pros
glseese once you removed the back and have taken your pictures to post with your question, check the TV according to the flowchart.
I recently had this issue and was able to find the same tv with a damaged screen that I could use for parts. After swapping the power boards. I still experienced the same issue. I then unplugged the board that controls the power button on the side of the tv and the problem went away. I then swapped the boards from the spare tv and all is working fine.
