My son hit the TV LCD couple of times. First it got a vertical line and then next day the line became thicker. After that one more line appeared same day and then half display became black and with the half black and white. And within hours screen turned black with sound on. I unplugged the power supply and plugged it back the logo of insignia appears and then screen goes black all the way.
Is anyone know which part I have to replace to fix it.
Thank you.
