Why is my tv not coming on

@johnnyc24

If your television is not turning on or showing any signs of life, see the Insignia NS-24ER310NA17 Will Not Turn On problem page for possible causes and solutions.

If your television is not displaying an image even though it is turned on, see the Insignia NS-24ER310NA17 Picture Does Not Appear problem page for possible causes and solutions.

Start by making sure it does not need to be reset. Disconnect every external input from your TV. Unplug the power cord. Push and hold the power button for about 45-60 sec. Then just plug the TV in and one video input source. See if it does now turn on.

If it does not you need to check the power board first. Remove the back from your TV and use a multimeter to check the voltages on the connectors against the values printed on the board. Let us know what it shows. There are plenty of reason why this could be happening and the most common failures are the power board and the main board. Post some pictures of all of your boards etc. with your question so we can try to help you finding some trouble spots. iFixitでの質問に画像を追加する方法
