Re: LG 55LM6200 Backlight shuts off



What is the BGA?...

The tv works great for 20 minutes or so. Then the backlight shuts off. It seems like a thermal issue. When I turn the backlight down to 20%, I get over 35 minutes out of it. When I cycle the power, the backlight will light for only 15 seconds or so. I would guess heat soak. When the backlight is off, there is an amber status led on the power board which flashes 4 times. Does anyone know what this is? Is it the backlight strips or the backlight control circuit? Does anyone have a legend for the status led?

Thanks,
Ken Maynard

New guy here. It's been 20 years since working as a repair technician (consumer electronics). But, since I've been seeing so many LCD tvs in the garbage everywhere lately, I thought it might be worth grabbing a decent looking one here or there. It looks like no one has them repaired anymore. Well, I'll be happy to repair them! Looking forward to utilizing your brains to accomplish this. Thanks everyone!
