The tv turns on you'll see the LG logo on the screen for 2 seconds then off. Red power button light then flashes twice. Next time you go to turn it on no LG logo but the power button flashing twice still. Unplug it and that process starts all over again. I looked at the power board all capacitors seem fine (still flat on the top). Also it is sending power to the T-con board because the fiber optic input still lights up red when the tv powers on for those couple of seconds. Anyone have a similar issue and  fix for it. It's a LG50uh5530 4K Ultra

    Same thing happened with our 50UH5530-UB today, 7-22-2018, for the first time. LG logo showed for a second then disappeared, red light flashed, then nothing. Won't turn on now, red light flashes three times. Could be a bad update?

    I have the same issue with my LG 50UH5530 - it started doing it today.  Won't show anything - solid red light then 2-3 red light flashes and that's it.  I've read about replacing capacitors being hit or miss - and have seen some other videos with diodes. 

    I bought this TV new on 3/19/17 and it's 9/1/18 and it's dead.  1 year warranty expired - made it less than 18 months.  

    I JUST replaced my entire home's appliance package with LG everything last month - DW/Induction Stove/Fridge/Microwave and my washer and dryer.  Let's hope they work out better than the TV did at 17 months of use.

    Same issue. I turned it on and it immediately turned off. Then tried to turn back on and it would not. I could hear something trying to boot. Also red flashing light twice. I unplugged the cord from the TV and then unplugged the cord into the outlet it did come back on and was fine for the rest of the evening. This morning it will not turn on. Tried the same process as yesterday 09/26/2018 and nothing changed. Still got the red flashing lights. One site suggested keeping it off for several hours. We really dont watch a whole lot of TV, it stays off more than it is on, when you compare it to the general population. We mainly just watch a bit of TV in the evening and thats it. I wonder if its related to a recent update. Our TV was bought in Oct 2016. I am not buying another TV. Remember the good ole days when TV's lasted twenty years? Well those days are gone!

    Seems odd that we are all having the same issue around the same time. Mine crapped out 10/3/2018, purchased 3/2017. LG support useless. Now there is a mad rush and demand for the power board, if you can find one. Anybody want a $600 boat anchor? Never buying LG again.

    LG 50UH5530 Same thing today 10/19/2018!
    TV is not very old, I shut it off, left for 4-5 hours came back and it is doing the dash dot dot routine with the red LED. Is it repairable or is it junk?

    Same thing happened to my tv it’s a 65UH5500 just happened last week 10/18/18. Unplug tv plug it back in and turn it on you get the LG screen for about 1 second then goes black and stand by light flashes. Seems very strange this is happening to others at the same time period. Also my tv is about 1.5 yrs old

    Same problem here, submitted a claim to LG for an extended warranty claim and it was denied! 18 months old and an obvious defect that LG is choosing to ignore. Would be nice to get some feedback from LG on this thread

    I see a lot of people having the same issue as me but no solutions. Anyone have any luck fixing it or working with LG?

     Same model-50UH5530 it happened today and I am trying to find some answers but I am getting more and more angry because all what I see that so many people are having the same problem and LG doesn’t do anything about it. I get it that TVs  don’t last as long as they used to in the past but common-not 2 years!

    We had that happen today.  Read this thread and prepared for the worst.  Turns out the surge protector/power strip was dead.  Changed that out and it's all good.
