Hello, I'm not a newbie at removing screens to replace leds, however I'm finding out that certain models like Sharp, TCL and Element have their screens glued down to the plastic frame. I've cracked a few in my day trying to lift them and have used razors to separate the glue from the frame. Does anyone have any other tips that they use to do this. Much appreciated.

Re: Removing screens
I just had the opportunity to disassemble a cracked screen Samsung UN65MU8000F that is glued to the bezel. I was really surprised on how easily the screen lifted when using a piece of .010 shim stock slid under the screen. It came up so easily that if I was doing a repair on the LED's I would be looking for a material to re-bond the screen to the bezel.
Then again, it may have been like this one that was falling out :-)

Re: Removing screens
I use a old insurance card. It’s about .010 thick plastic and separates the glue from the screen easily without damaging it. Sometimes I warm it with a hair dryer just to loosen the adhesive as well.Comment

Re: Removing screens
I cut a credit card in an L shape so it can slip past the raised areas of the bevel.
I also grease the surface of the card with wd40 so it wont reglue as it flattens behind meComment

Re: Removing screens
One of the safest ways I have found is to heat a Ufix bean bag up in the microwave for about 1-2 minutes and lay it on top of the panel where the adhesive is for about 3-4 minutes and slide a plastic playing card carefully underneath the panel and once it starts to slice through the adhesive leave the card in place and go onto to the next section so have the whole deck of cards ready. If it's a bezeless design the adhesive will be all the way around or on 3 sides only depending on the model. On some models you will be able to see the white sections of adhesive barely sticking out like on some Sony's so you can see where to apply safe heat to loosen the adhesive. You can get the Ufix bean bags at cell phone repair supplier's or shops or try Ebay. Good luckAttached FilesComment

Problem
This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached.... -
I have peltir element glued to heatsink with something thick and sticky like putty... it cant be separate with force or heat without risk of breaking ceramic or damaged semiconductor layers due to force (eg if try twisted, pulled, lifted)... method that I am using is a single thread for needle (thin and firm thread of pure polyester that cant break with bare hands without glowes), and using it like a saw between heatsink and peltir. I holding a heatsink with knee against table. It slowly cut throug putty and release glued parts. It is slow proces, but preserve undamaged component and heatsink....

Some new tvs have an LCD screen attached to the outside of the frame with foam tape. These are "edge to edge" as they are called. I am trying to figure out how to reattach an LCD panel back up to the frame. The manufacturer used 3/16 inch foam tape along the top and rh/lh edges. I used a razor blade to separate the panel from the metal frame. The metal frame that the panel is taped to is 1/4 inch wide along the 2 sides and top. I completely removed the residue from the metal frame. There is some residue on the panel itself along the 3 edges, I removed almost all of it using alcohol and... -
