I ordered replacement LED strips for my Sceptre TV. I'm getting ready to install them. What adhesive do you all use to adhere them to the case? I'm looking for something I can pick up in a brick and mortar Lowes/Ace Hardware place.

Two way tape. Like the stuff you get when you put the hairdryer shrink plastic on winter house windows.Attached Files -

Re: Adhesive to Hold on LED Strips?
Problem is you don't know how well those tapes transfer heat into the metal back side of the lcd/tv panel ... the led strips probably use the back metal to spread led heat.
You can use thermal pads or sheets, here's a starting point (selected only ones with adhesive on both sides) : https://www.digikey.com/short/p95d7h
An example:
26$ for 640 mm x 320 mm : https://www.digikey.com/product-deta...359-ND/3042188
15$ for 320 mm x 320 mm : https://www.digikey.com/product-deta...361-ND/3042190
15$ for 320 mm x 320 mm : https://www.digikey.com/product-deta...358-ND/3042187
3.5$ for 150 mm x 150 mm : https://www.digikey.com/product-deta...360-ND/3042189
3.5$ for 150 mm x 150 mm : https://www.digikey.com/product-deta...357-ND/3042186
7$ 150x150 : https://www.digikey.com/product-deta...363-ND/3042192
7$ 150x150 : https://www.digikey.com/product-deta...366-ND/3042195
add around 5$ for shipping.
For a 640x320mm you can cut strips ~5mm wide (~ 0.2") and you can cut 64 segments out of it. You end up with 64 x 640mm = 64000 mm or 41 meters of strip
Or cut 15-16 mm wide strips... whatever divides nicely 320mm or 150mm into equal segments.
... and you may not have to apply the strip continuously, could leave some spaces to save on the adhesive strip.Last edited by mariushm; 07-13-2019, 12:19 PM.Comment

Use this stuff, it's designed for thermal transfer. https://www.ebay.com/itm/Chip-Protec...k/173940996456Comment

Ok.. this is the story:
Have an old Samsung LED 3D TV (UE55F6475). First it started to lose light on the lower 40% of the screen now and then. Like for 10-60 mins and then it would work again. Then a bit later it just got stuck in that position. The lower 40% of the screen is dark, and it gets progressively darker the lower u go so it's obviously that LED strips where not working. I also looked for similar errors online and saw an exact copy and on that one it was faulty LED strips.
This is kinda how it looked, just that mine were at the bottom of the screen:

Hi There!
I bought a broken 32" TV today. It has sound but no image. I checked with a flashlight and it was missing backlight
Disassembled down to the led strips and found this TV has been serviced before. Not sure if it was fixed, worked again for some time, and broke again, or maybe last repair wasn't successful
Looks like on previous repair, the center LED strip was replaced with a different model, 7 leds in it instead of 8, but when checking LEDS one by one, leds on the center strip were brighter with same test voltage (multimeter in DIODE mode) so maybe the... -
I suspect a lot of you have done a lot of repairs and end up with a lot of bad LED strips...what do you do with them?
Wonder if I should get a pile of LED chips and try to replace the bad units for the heck of it, but I don't really need the strips at the moment because I bought the strips...
Oh... and I think I got my TV working again, though not 100% I don't think, on a white screen I can see a bit of the ghost of the LED strips, must have done something wrong or the LED strips aren't quite the same as the original... -
Hi guys,
I have one very old TV.
Main problem I have with this tv is that led strips won't light.
I measured voltage levels, and inverter input is 24V.
other voltages are also ok.
What I found is that removing and connecting again connector CN1 led strips lights for shorts time (but only once). When led strips lights up then light is uniformly spread on whole panel.
First I thought that led strips are dead, but I'm quite sure that problem is not strips related.
I don't know what voltage level is at output of inverter board (samsung SSL400_3E2A) and how... -
Hi,
I am in the process of replacing the backlight boards on the LG 65UH9500 TV. It requires the separation of the front glass/panel to get to the boards. The panel is help on to the frame with some kind of strips that I cannot reuse to adhere the screen to the frame. Anyone have any experience/Ideas on what I can use to securely hold the 65" Panel to the frame. I would hate for the panel to fall face forward. Thank you in advance....
