Had wrong model number corrected in this post, unable to edit the other
showing power does nothing randomly turns on with 2 flashes: https://youtu.be/ZHME8GthErc
Hello all I have an issue with my tv. I have had it for about 5-6 months because when I moved apartments the previous owner left the tv. and I got it for free it is a plasma tv and looks nice enough. an issue that started to happen was that it would kick off randomly but I could still turn it on well about a month or so I assumed the power button went out so I got a universal remote and programmed all lg codes and nothing just the solid red standby light so fast forward to a week ago and i got curious so I opened the TV up after find this video https://www.youtube.com/watch?v=C7UChm5b_rw same issue press power button still in stand by. sadly I dont speak this person's language andddd the auto generate CC is a bit hit or miss so I knew where to solid the transistor.
I got a similar spec'd transitor as finding those transistors are difficult as they are disconnected, so I looked at a datasheet, found some info but went to an electronic discord to make sure everything was correct and what I should look out for, they told me as long as it drives with 4 volts on it would be good. I found a transistor that was 4 volts power on. and confirmed with the discord people that the transistor would be suitable for my needs. so I got it today and went to work well my soldering skill sort of suck right now so I couldn't get it on well, but enough to test so I pressed the power again no luck well I decided to just remove the leads and see if it powers on by some luck and to my surprise it did, but something was off... there was a logic control board that
flashed 2 times in sync with the stand by indicator but it turned on none the less.
i was happy it turned on then it randomly turned off as I was texting a friend that it works but I am not sure why. then you see in my video pressing the power does nothing after five minutes it randomly turns on I dont think using the av cables help it was just sort of dumb luck now it turns on for maybe 10 mintues turns off for about 5 then back repeat repeat repeat.
