I got some before from aliexpress that seems to work pretty well. No idea if genuine. Search "3M 5952 4mm" Probably good to check the width after cutting the screen open.

On no bezel LCD panels, here are some dis/reassembly notes

• 2012+ iMacs also use double sided tape to glue on screen. A plastic pizza cutting wheel tool is used to cut open the iMac screen. This is probably more desirable than a non rolling cutting tool to minimize producing debris on the back (clean) side of the LCD panel that has to be ultra clean.
• I took the time to painstakingly remove the old tape from the backside of LCD panel (wear nitrile gloves to keep the LCD clean). This exposes this clean side for long periods with more chance to collect debris. Debris can only be discovered after nearly full assembly to power on TV to show a white screen to examine for debris. I unfortunately cracked the LCD while tilting the LCD from one corner trying to use sticky tape to remove the debris. Ideally, use compressed air to blow clean the clean side prior to assembly. Also avoid sticking on the LCD prior to checking for debris. If require 2nd LCD removal to clean debris, use something like masking tape to mark the location in front of the LCD to locate the debris then remove LCD panel completely for cleaning. Mine cracked because I tried tilting the LCD as a short cut to get to the debris. LCD probably wouldn't have cracked if I had a 2nd person to lift and tilt the LCD from both corners.
• Also note LCD panel's strength is deceiving. The 2mm+ thickness is mostly a strength providing glass. The actual LCD is patterned onto a super thin glass that is glued to this thicker glass. This ultra thin glass is what cracks and not the thicker glass.

Good advice for fixing the TV and the debris.

My advice is just forget about it lol. The headache that this type of TV repair isn't worth it. Debris gets everywhere from having to cut the tape to get the screen off. The tape is black and so is the screen and it sticks really well to the TV after cutting. Impossible to see until you put it back together. It can definitely be done because I have done it.. but it's not much worth it. But howards tips are very nice.

Since it seems your job is repair tvs good luck! Ali Express or eBay has the tape

Lool, I think this is a good advice! I will try to get rid of it politely as cannot see a good end for both of us!

In my experience it's not worth the headache. I can do backlights all day no problem. Once I have this TV with the tape you have to cut .. it's always a pain in the ass. Debris behind the screen makes you feel unprofessional so you have to fix it.. and then it takes 2x longer then you wanted. I'd say good idea.

I have repaired a few Hisense "no bezel" LED TVs. These are definitely a real pain to work on. I charge extra for repairing these since they are so much extra work.

To remove the double-sided sticky tape, I use a sharp box cutter (X-acto) blade and gently cut by moving blade back and forth. This minimizes small debris by not totally disintegrating the foam into smaller pieces. Do not use too long of a blade since you do not want to scratch the delicate LCD panel on the inside.

Once LCD and frame are separated, the factory adhesive rolls off the panel and frame pretty easily by simply using your finger tip in a forward motion (like pressing a button repeatedly with your index finger) and once you get it started, it kinda rolls together into a small ball. Yes, this will leave some finger prints and adhesive residue on the outer edges of the LCD panel, but use 99% isopropyl alcohol (ask for it at your pharmacy, it is usually behind counter).

This adhesive tape is special. It is actually a double-sided foam that is quite thin. No doubt you have already realized it's pretty flexible. The foam permits a little bit of movement between the panel and the frame. I have tried regular double-sided tape but while it stays stuck to the LCD panel, it almost never sticks well to the frame coating and even though the TV went back together perfectly, after a few weeks I noticed the panel coming off the frame at the corners. This could have been catastrophic if the panel completely detached and fell forward causing it to crack. Maybe 3M makes a better product than I used, but my advice is to be careful.

My solution was to re-clean the surfaces and re-apply the double-sided tape, AND ALSO use a small amount of black RTV silicone (from your auto parts store) at the upper left and right corners and even at a few spots along the top and sides of the panel (between panel and frame) to ensure the panel doesn't detach from the frame. While fresh, the RTV can be wiped clean and is practically invisible so you or your customer will never notice it.

CAUTION: If you decide to use RTV, be very careful how much you use. If you use too much, it will squeeze outward and inward as you apply pressure and could appear in the corner during viewing if it covers any of the pixel area. Anything squeezed outward is not an issue since it can be wiped away.

As stated, this is very good for long term repair where you won't have to worry about the panel coming off due to crappy tape. Even good tapes can fail over time as they warm up during use and start to stretch. The RTV provides a very good bond, and is easily cut with sharp blade if you ever need to re-open the TV.

Perform this work on a flat surface with the TV supported appropriately from the back side so that there is no twisting of the frame. If it is not perfectly level or flat when you re attach the panel, some forces will be applied when TV is put back to vertical on it's stand and this will work against the adhesive.

Some other thin foam adhesives might work perfectly, but I did not have any to try at the time.

Best of luck.
