    Question LG 65UF6450 - Won't power on, no backlight

    Tried it out, either my heat gun just doesn't get warm enough or it didn't work, same set of issues as before :( I was focusing on the main processor after removing the heatsink, but maybe the cause lies elsewhere? Edit: My heat gun only goes up to 165 Celsius, not nearly hot enough...

    Question LG 65UF6450 - Won't power on, no backlight

    That about sums up what I found while researching a bit lol, I definitely don't have the tools to properly reball the BGA. I'm fine with a temporary fix as long as it means the TV runs again - if it does, I'll consider getting it repaired professionally, I just want to know that it still...

    Question LG 65UF6450 - Won't power on, no backlight

    I'll try blasting the chips with a heat gun later today when I have some more time, just watched a few tutorials on it and it doesn't seem too bad at all. I'll report back and let you know how it works - not like I can break this TV any more than it's already broken, haha. Thanks again for your...

    Question LG 65UF6450 - Won't power on, no backlight

    $99 even is a lot, I'll have to think about it before sending it in. I'm just about to test the connections with the main board unplugged and I'll get back to you after that. I'm fairly confident in my soldering abilities but I definitely don't have the tools to reflow or solder BGA chips lol...

    Main board is disconnected from the power board, no backlight when I plug it all in

    Question LG 65UF6450 - Won't power on, no backlight

    Made sure not to touch anything on that side, all the videos I watched said the same thing lol. Is there anything else I can do from here on out to get this thing working? Now that I know the power supply is fine, I suspect something is wrong with the main board but I don't know how to fix it.

    Question LG 65UF6450 - Won't power on, no backlight

    I'll give that a try asap! I may not have time tonight but if I do I'll make sure to report back. Otherwise I'll have to test it out tomorrow. I wasn't entirely sure how to test that all with my multimeter, so this really clears things up. Thanks! Edit: I'm getting the right voltages where...

    Question LG 65UF6450 - Won't power on, no backlight

    Tried it out, when shining my phone's flashlight on the screen there's something there, but not what's supposed to be there - the left half of the screen seems to turn white for a second or two before turning black again for another second or two, over and over. There's no text or anything that...

    Question LG 65UF6450 - Won't power on, no backlight

    Hey! First post here, hope this is the right place. Some backstory - this TV was given to me by a friend, it was having issues and they ended up getting a new one. It survived a lightning strike a couple years ago and worked fine for a year and a half or so after, before it started to...
