Relatively new to TV repair - as you will see. Rescued this TV from the curb. No backlights, but I could see an image on LCD with flashlight, so suspected bad LED strips. When I got to the part of lifting the LCD off the frame, it was stuck a little bit from some tape used to hold down a thin layer of foam around the frame. I saw 8 tabs on each side of the LCD that I haven't seen on any of the 3 TVs that I have taken apart before. I immediately thought, wow the engineers that designed this were thinking about the serviceman when they put these lift tabs on here - good for them. So I started yanking on them to free the LCD screen, and it worked really well, but one of them came off. It was then that I saw it was actually a printed circuit - damn! Hope it wasn't important! After replacing LEDs, put it back together, and the backlights worked, but all kinds of funky stuff going on with the image.
After researching this forum, I found some instances where people reported success by removing all the "lifting" tabs from one side of the LCD. So, I removed the other 7 tabs from the one side, and was amazed to see that the TV is working great now!
The moral of this story is don't be a dope like me and think these tabs are lifting aids. But I also have a question, why do they install these COFs on both sides of the screen if they are only really needed on one side?
