Question about Toshiba Televison & Video
My tv recently went blank. I do get power and do get a green light and can see image when I shine a flashlight so I assume it was the backlight inverters that went out. I replaced the backlight inverters and now the tv does turn on but for only a second. I noticed when I turn on one of the inverters seems to make noise and it smells like it burns when I try turning it on. What could be causing this? Power supply? Bad LED lights? Is it normal for the inverters to make a type of buzzing noise? Maybe it wasn't the inverters after all? Thanks for the help
