Hi M Smith, it indicates what model of Insignia it is, to know what type of Back Lighting it has
The problem you describe would seem more like the feeding stage of the Back Lighting, and may also originate on the T-Con plate
Comment the model, to find a better solution
I wait your answer

Hola M Smith, indica que modelo de Insignia es, para saber que tipo de Iluminacion trasera tiene
El problema que describes, pareceria mas de la etapa de alimentacion de la Iluminacion Trasera, pudiendo tambien originarse en la placa T-Con
Comenta el modelo, para buscar una mejor solucion
Espero tu respuesta
Saludos Franco Dosil

Sounds like LED strips are bad
