Hi Andrew, try replacing the tcon board

Hello William, for what you say, you have a problem in backlighting
It can be the source that feeds the LEDs or that the lighting LEDs are wrong
the solution, replace the led strips, that do not work,
Correct solution, change all the LED strips of the backlight
I send you a video where they show the procedure
I hope you can solve the problem
Greetings Franco Dosil

Hola William, por lo que cuentas, tienes un problema en la retroiluminacion
Puede ser la fuente que alimenta a los Leds o que los Leds de iluminaci?n est?n mal
la soluci?n, reemplazar las tiras de led, que no funcionen,
Soluci?n Correcta, cambiar todas las tiras de Leds de la retroiluminacion
Te env?o un v?deo donde muestran el procedimiento
Espero puedas resolver el problema
Saludos Franco Dosil

Hello Kenpappas, for what you describe, it would seem like a backlighting problem
questions if you can have a bad led ?, if many times a Led, is the one that proboca the failure
The correct solution from my point of view is, replace, all the Leds
As it is not practical to replace each led in the strips
It is more practical and simple, replace the full strips of leds
I send you a video, in which they show, the procedure of replacing the LED strips on a Hisense TV
I hope you can solve the problem
Greetings Franco Dosil

Hola Kenpappas, por lo que describes pareceria problema de retroiluminacion
preguntas si puedes tener un led mal?, si muchas veces un Led, es el que proboca la falla
La solucion correcta desde mi punto de vista es, reemplazar, todos los Leds
Como no es practico reemplazar cada led en las tiras
resulta mas practico y sencillo, reemplazar las tiras completas de leds
Te envio un video, en el cual muestran, el procedimiento de reemplazo de las tiras de Leds en un televisor Hisense
Espero que puedas resolver el problema
Saludos Franco Dosil

It needs a complete array of LEDs

Cheaper to replace than fix, trust me on this.

THE TV

i assume this is an lcd, not led tv. the flourescent backlighting's inverter unit has gone out. its usually a seperate ic card, so it is repairable, if you can source the part cheap
