When I turn it on, it looks for a second, the LG logo then turns dark but the image is seen when I illuminate it with a flashlight. The rest, like volume and functions, continue to function, the model is LG 47LA6200.

Hi. may have a problem at the source or inverte

my dear jormobi, without offending and respect first of all I ask you, are you a technician? If the answer is positive you will notice that the screens have backlight and are of lamps or LEDs, I want to think that yours is LED, and as you say you have that damaged lighting, some strip or even a single LED, you have to remove frame, panel, diffuser and reach the lighting (the LEDs) and there you measure and replace the damaged one and close it again and work it, all this with the greatest possible care with the panel since they are very delicate. If your answer is negative, I recommend you take it with a qualified technician. salu2
