white light on LCD TV display

"I had the same problem and it's really simple to solve! The 16 dots you're seeing is the light from the LED backlight. In front of the backlight there's a plastic cylinder very casually glued over it (thanks LG) that diffuses the light, when that drops you see the LED light directly projected onto the screen which causes the white spots.

You just have to dismantle it (not too hard), buy some glue and paste those plastic pieces back."

"Hi Lance,

Thanks for your input. this is same as the problem you said and solved it. i have attached the cylinder picture. i have applied little glue on the 3 supporting dots and stick it.https://goo.gl/photos/ZcPD8B8dKQbaF8SVA"

Thanks guys! I just replaced the leds for my tcl 55 inch tv and after bout a week I started seeing the bulbs on the left side of the screen. Since the tv was an awesome find and the bulbs were like 30 bucks on eBay I’m fighting the inevitable being going back in and fixing that plastic deflector post. The screen is extremely fragile so if u don’t wanna pay 14 bucks at Home Depot for them window suction cups that were well worth the money For loners like myself lol, make sure u get another person to help u with the screen panel once it’s been dislodged . Especially if it’s a big honker. Nothing more scary than popping it out by urself and get stuck in a very bad situation as in u can almost hear the crackin of the screen Or knowing that I’d u take one more step this here screen will crack .

"Is using a hot glue gun recommended for this fix? Using glue sticks made for metal.

If not what kind of glue is recommended?"
