Hello Steve, for what you are saying, it could be that some light diffuser has been detached from the back lighting, to see if that is what you can try, turn the TV and try to listen if there is something loose, if so, you should disarm the television until you reach the back lighting and paste the diffusers in the corresponding places, check that the rest of the diffusers of the LED strips are firm, so that the problem does not happen again
If you hear something loose and you do not have knowledge of how to disarm, look for a specialized technical service
I hope you can solve the problem
Greetings Franco Dosil

Hola Steve, por lo que comentas, podr?a ser que se haya desprendido alg?n difusor de luz, de la iluminaci?n trasera, para comprobar si es eso puedes probar, girar el televisor y tratar de escuchar si hay algo suelto, si es as?, deber?as desarmar el televisor hasta llegar a la iluminaci?n trasera y pegar los difusores el los lugares que corresponden, comprueba que el resto de los difusores de las tiras de LED, se encuentren firmes, para que no vuelva a ocurrir el problema
Si escuchas algo suelto y no tienes conocimientos de como desarmar, busca un servicio t?cnico especializado
Espero puedas resolver el problema
Saludos Franco Dosil

My TV is a LG 47LN5700-UH I had a lightning strike near the house. Afterward TV would start but not boot completely. Now it won't start at all. Cable box also got fried at the same time.

The led driver AND the T-con board are bad. If you could see a picture with the flashlight then the T-con board would be good. It is not. The led driver can be on the main board or the power supply board. You can get these parts from here: TV Parts Universal TV Stands DLP Chips ShopJimmy

LG 55LH90-UB LED TV I have an LG 55LH90-UB LED tv that has, what seems to be, sections of dim areas.

Hi ,
try swapping the screen with another one to just see if it is behaving the same, because some times the screen circuitry or the led screen could be damaged .

good luck buddy

I have a LG 39LN5300-UB television I have audio but no picture I have replaced the T-con and the Power supply boards. What else could be causing my problem?

Hi Gragory,
It is the back light.Some of the LEDs in the array have failed. Please open the box and check. You can replace individual LED or the strip as a whole. Please be careful while taking apart the LCD sheet.
Good Luck.

No picture, only sound on LG 47LV5500: how do I get picture back?

Definitely odd for sound to come through and not sound, especially via an HDMI connection.

I would contact LG for support, your TV could be defective.

Good luck
