i think your capacitor is blown, do a google search for insignia, lcd, capacitor...
you can buy another one for about $2 but its a pain to install, you can also instead buy a new powerboard for about $80, its an east install and you wont blow more capacitors

This is usually the high voltage on the inverter, balancer or backlight arcing to the chassis or at the connections. One quick fix was to look for a burn spot under the inverter(s). If that's the case, insulate the chassis at the point of the spot with a few layers of electrical tape 600v dialectric strength or better and carefully clip the leads just above the solder joint on the inverter board to widen the arc gap. If the white pink wire connectors arc too long they will charr requiring replacement. Cost varies depending on the problem.

Possibly the power board or the sustain board has died.
Power board failure does not stop the blue light from working as this is an LED on voltage side of power transformer. The set fails because it has detected a voltage difference in one o0f the other boards that controls the initial starup and convergence. Some transistors and capacitors are also possibly involved. Not a dIY unless you are skilled. Parts $300 labour ?
but about $400
