Question about Insignia NS-L42Q-10A LCD TV
Does tv give sound while screen is black?
Can you change tv channels or change volume level in tv?
If yes, then point good flashlight on screen front and try to observe faint image on screen. Once you see image then problem is with back light inverter board that is not producing light behind lcd screen to show its picture.
And if tv does not give sound nor any faint image found in screen then it would be power supply board issue.
Let me know your finding to solve the problem.
Is it Insignia NS-L42Q model tv as shown in question header or some other model?
