Some info and some questions
Hisense 50R6E manufactured December 2018 and already a backlight failure. One of 48 LED's located on the top strip was open causing a total shutdown of the other 47. The backlights are wired in series and I suppose this means they don't incorporate a zener or other device to keep the set running if just one LED opens.
The white reflector shield was quite difficult to remove but doable with care - picture attached showing location of tape. The missing section was under the wires. Some sections of double sided tape seemed stuck better to the metal, and some to the reflector, but I tried to stick with one or the other.
I went ahead and replaced the one bad LED while waiting on strips to arrive and powered the set up with just backlights. It was kind of odd that when first plugged in and switched on the backlight voltage is 163 V with 475 mA of current. That lasts about 10 seconds with a brief off interval where it then changes to 380 mA. I suspect I will find the backlight setting at max when the set is reassembled. Current measurements were taken with a current probe.
So, the question is on the installation of the LED strips. This set used what appers to be a thermal adhesive, which I have also seem recently on TCL - pic attached. Is the consensus to repeat this process, and if so any recommendations on thermal adhesive product?
Or, just use a double sided tape, and if so any recommendations here on product that works well? I recently got a roll (pink) from shopjimmy and was kind of disappointed in that it was not spec'd in W/m-k on either the website or with the received product.
