Re: Some interesting replacement LED strips
good found budum, yes most direct LED used Forward Voltage: 3.05-3.65V because Reverse Voltage (VR): 0.8-1.2V (5mA) so its fine to SMD LED 2835..
but this not enough the problem they didn't mentioned to Forward Current where should be round 400mA , and the most important Pulse Forward Current where it need be round 650mA , with those range the dimming and brightness will work on 90% LED background
waiting for budum receive his order and his own measure.Comment

Re: Some interesting replacement LED strips
I got reply back form seller, it is rated at 330mA MAX so it is about 1W LED, no peak current rating provided.Never stop learning

by mc900fthannaSo... I have the patchy back light issue with my Visio M70, meaning some light up, others do not. I finally got around to testing the LED driver board and found that was not the issue (swapped another one in and the same issue persisted) and I am considering if i dare dive deeper into this TV and go after the LED strips.
Right away i see that they don't seem to stock them anywhere out there (E700DLB0016-002) is a part number that i see a you tube / seller guy list out. He has a nice video of how to get into my exact TV out there: https://www.youtube.com/watch?v=0AcUPiN83Tg

by lmcancuHi I am having an issue with the LED backlight of this TV. I can see the picture with a flash light, so I determined it was a backlight issue.
Initially, after opening it I found 2 shorted and 1 open LED on 2 strips (total of 4). I removed the LEDs and shorted the pads together to verify if the backlight would work.
Testing it, I found the backlight turned on and I measured 54V when TV was in standby (off), and 100v when TV was turned on. The 4 strips each contain 9 LEDs, so 36 in all minus 3.
Instead of putting it back together I decided to replace... -
by anupkg1985Hi,
I have this Insignia tv with most of the led's damaged. I'm not able to find the replacement LED strips for the same. The numbers marked on LED strips are -
LB-GM3030-GJBETTY504XBBB19. Please find the photo for the same. Can somebody help finding replacement/equivalent led strips for the same.... -
Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?by Tynan DillI was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.
Assuming...7 Photos -
by KingfreddieOk.. 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:
