I've got a problem, one that I'm not an expert on. Basically I have a big LCD tv made by LG that I got back in 2009. It's worked absolutely fine over the years. I've never had a problem with it until now. Whenever it would get dirty I would often see dust buildup very lightly every four months. I'd wipe it away with a store bought LCD tv screen cleaner liquid and a clean microfiber cloth. Same deal every four months until...
Lately I've been having sleeping problems. So I decided to make use of the aquarium channel on my HD cable box. Basically it's a channel that shows a live aquarium with water flow noise all day long. Mind you I know about screen burn in. But I didn't think it would be a problem to leave the channel on while I slept this past month. Because the channel goes fully black every 15/20 mins.
Then came the day a week ago where I was watching a movie and noticed what looked to be very clouded areas on the tv. Almost like dark smudges... I figured it was dirty so I went ahead and cleaned it. That didn't remove anything, so I cleaned it again. Only to realize its not dirt, it's clouded areas of darkness on different parts of the screen. I believe that even though the aquarium channel (which I would let run it's course for 7/8 hours every night this past month), has probably caused some sort of clouding/burn in because some parts of the aquarium were black. By that I mean the fake reefs in the aquarium which were never really lit up, so when the screen would automatically go fully black every once in a while that probably didn't help at all because some areas were always dark.
Is there anyway for me to fix this without using software? At worst case I'll use software, I just hate installing new stuff. Anyways I've seen some screen burn in videos on YouTube that flicker colors or black and white for hours or less time. I have no idea if that works. I also saw a guy on Youtube say you should hold a cold ice pack in a cloth against the dark areas of the screen and comments swear it fixes it.
Please advise me as to which is best. I feel like using one of the burn in color videos on YouTube but need your advice before I go ahead with that. In case it makes things worse.
Thanks + Happy holidays
