As per some communication I've had with Shop Jimmy they must be getting more than a few requests for them. Admittedly a niche item but there you have it.

Re: SJ to Begin Stocking LED Strips
Yep it's becoming a real major problem. I keep LED strips after each teardown of a cracked screen set. They don't heatsink the LEDs properly.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: SJ to Begin Stocking LED Strips
So you think its heat, eh ? I was going to use thermal paste down the length of the bar when I reinstall it just in case...Comment

Re: SJ to Begin Stocking LED Strips
Two major things kill LEDs.
- Heat, lifetime approx halves for each 10°C rise in temperature.
- Mechanical mounting stress, flexing the diode.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

And overvoltage from having a several in series short out ??Comment

Re: SJ to Begin Stocking LED Strips
That just causes heating leading to the typical failure mode.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

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... -
Hello everyone!
Recently I've noticed that some ShopJimmy backlight strips don't have double-sided tape installed upon them when an application calls for it, and I must purchase the tape separately. In a recent chat conversation with a customer service agent I told them if this tape wasn't applied when it was called for I would begin to consider ordering my backlight strips elsewhere. It looks like this time may have come.
I recently got a TCL 65S4 with bad backlights. After looking at the SJ listing here: https://www.shopjimmy.com/tcl-jl-d65...365as-m-led-ba...Yes0%1All backlight strips are the same quality0%1No0%0
