Open internal fuse or power supply failure

LG Televison &... | Answered on Sep 14, 2019

It is broken. Take it to a registered LG service engineer. DON'T try and fix it yourself. People on Fixya try all the time, but it never works. You need to do the 2 year course and learn how to diagnose at component level. There are some good videos on YouTube that show this and reveal what knowledge these people have. Another big problem is that 'Guaranteed' boards you buy off ebay and stripped from scrapped televisions and are faulty, so you replace a board and it doesn't work, so you buy another, and another, and then all the boards have been replaced. The problem was that your first replacement board was kaput!

Also if it is a plasma, it is old. Time for a new 4k Ultra-HD set, technology has moved on.

Power supply failure if mains power is OK

LG Televison &... | Answered on Sep 06, 2019

The click sound is the power relay coming on and off. The tv is sensing a power problem and shutting itself off. If you are handy, remove the back of set , disconnect the connectors to each board and check voltages out of the power supply. If they are not to speck, replace power supply board. If they are ok, reconnect one board at a time and see if power stays on. You should be able to find the bad board this way. Visually inspect each board for burned components or swollen capacitors.

Your backlight inverter board is likely bad. If you're handy it is relatively easy to replace. Google for replacement part.
if you can see a picture while shining a flashlight on the screen then it is most likely the inverter board. Backlights provide the light through the lcd screen for brightness.

Hi Larry, for what you say, you have badly the Main Board or the LCD Panel, you can try disconnecting one of the connections between the T-Con Board and the LCD Panel and see if you see a half-screen image, try disconnecting one at a time , if half of the image appears in any of the image, the problem is in the LCD Panel, if nothing appears, then you would have badly the Main Board
I hope you can solve the problem
Greetings Franco Dosil

Hola Larry, por lo que comentas, tienes mal la Placa Principal o el Panel LCD, puedes probar desconectar una de las conexiones entre la Placa T-Con y el Panel LCD y ver si te aparece imagen de mitad pantalla, prueba desconectando una por vez, si te aparece en alguna la mitad de la imagen el problema esta en el Panel LCD, si no te aparece nada,entonces tendrias mal la Placa Principal
Espero puedas resolver el problema

Hi Troy, when you say blank screen, it's an illuminated screen or you just want to say a screen without a dark image
If it is the latter, it is very feasible that the fault is in the LEDs, try turning on the TV in a dark room and with the help of a flashlight, illuminate the panel on the inside and back, to see if there is an image
If the case is a screen that looks white, the lighting would be fine and the problem could be on the Main Board
Greetings Franco Dosil

Hola Troy, cuando dices pantalla en blanco, es una pantalla iluminada o simplemente quieres decir una pantalla sin imagen oscura
Si es lo segundo, es muy factible que la falla se encuentra en los LED, prueba prender el TV en una habitacion oscura y con la ayuda de una linterna, iluminar el panel en la parte interior y posterior, para ver si hay imagen
Si el caso es una pantalla que se ve blanca, la iluminacion estaria bien y el problema podria estar en la Placa Principal
