Can you use a moderate amount of heat to remove a LED panel if its stuck. It seems the felt pads on the frame under the panel have stuck to the screen preventing east removal

Re: Led panel removal
Dont use heat. Certain tvs use adhesive to glue it down. I use a .25mm feeler gauge. Its strong enough to slice through the glue and flexible enough to bend over the humps in the frame. Just take your time. -

Re: Led panel removal
My technique is with fine fishing line (0.25 mm). Take the thread from both ends and begin to slide it under the screen, from top to bottom, starting from one of the angles. Be careful with the panel's flat flex cables.Comment

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... -
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.... -

TV flashes backlight then reboots over and over. no image. Client said it used to have image for a bit before rebooting. Got worse over time.
tcon is built into mainboard.
Only one cable goes to panel boards.
there is a cable from one panel board to the other that links them.
cost cutting measure that results in us having harder time to diagnose.
removing the link to the second panel board allows TV to stay on with stable backlight but no image.
used cut off tape method to mask 1 maybe 2 pins on the side of the cable that goes to that second panel board.... -
I had a the above tv qn55q60r that had a bad panel but everything else good. I had another panel here from un55nu6900 with bad leds and melted diffusers.
I put the nu6900 panel in and powered it up and it does work but there are lines vertical lines.
I was trying to change the panel type in the service menu but don’t see my exact panel. Anyway to fix this or someone have similar experience.
