No picture, no sound. Can't turn on

@klearly26 Can't turn on is usually an indication of a power supply issue. Make sure that your outlet works and that your power cable is working properly. After that, you will need to remove the back cover from your TV and check the fuses on the power board. You will need a multimeter (inexpensive department store brand will work for this). If unsure what to test where post some pictures of your boards etc. with your Question. You also would want to verify that your TV is a Sanyo dp50747 if not then let us know what exact model it is. If it is then start with this Sanyo dp50747 Plasma TV fuse replacement and power board check
