Sceptre 48" TV backlight LED`s

[spirittoo]

Trying to fix a backlight problem with a Sceptre 48" TV.

I found replacement strips with the same part number as the strips in the Sceptre, but the new backlight strips have 5 leds per strip and the ones in the tv has 6.

So I decided to replace the leds instead. I found 3 bad ones. I had no problem removing the bad ones with a heat gun, they came right out. However the leds on the replacement strip would not come out with heat. I use my solder iron as well, they will not come off.

Anyone know how I can remove those leds without damaging them?

Put soldering iron on table lay the strip onto the iron and keep the heat going until it comes off with the tweezers. It's really not easy to do. You can buy individual LEDs on ali express or eBay if you can't figure it out.

Here are some photos of the strips. The part number from the old strips and the numbers that was on the replacement in the following photo.

Eazy why was it easy to remove the bad leds with a heat gun but these new ones won't ... I don't understand that. So I need to keep at it with the solder iron until it comes loose?

Thanks for the link ... so you think this tool will do the job ... I will check it out.

I don't know why lol, I never replace just one led anymore, always all the strips. Too many issues doing just one led, maybe if it was my home TV bu

did you get the rite voltage plate for your country ie 110 or 240v all i did was connect the two leads to a wire and plug (heat shrinked the joins) the small bag is the stand offs fot the heat plate so it does not burn the surface your using it on. I just plug it in then place led strip with led you want too remove central on the plate, let it heat up then remove the led.https://www.youtube.com/watch?v=qxpAGFuKPmg

I don't understand why you wouldn't just buy the correct LEDs.

69 ... thanks for that link I would have never have figure it out. I don't see anything about voltage ... just amp <5 that's it. I'm hoping they sent the right voltage since it was coming to the states.

Eazy ... I could not find the correct leds so I got the strip that had the same part number as the strip in the tv.

on the metal part of the tv chassis there should be a white sticker saying what lcd panel/number is used in the tv what is that? replacing the odd led can sometimes cause bright spots on the screen and its also hard too fit the lens back on correctly without it showing as a halo mark etc when watching tv so i agree if possible change all led strips for new (i have replaced the odd led before but its not long until another fails then you have too strip the tv back down and another risk of damaging the lcd or tab bonds)

When a LED is brighter then others you can fix it by taking a permanent marker and putting a bunch of black dots in a circle around the brighter led going out about 2-3 inches from center light. Neat trick. But I change out all lights. Cause in my short experience it gonna fail again

That is the number on the strips I bought as well as the original strips in the tv.

I just could not find a replacment strip with the 6 leds ... all just had 5 including the one with the same part number as the original.

did you try searching using the lcd part number off the white sticker this sometimes helps with locating correct led strips.

I want the model number of the TV not the lights. My lord

Ahh okay, I see now, odd model number.

At this point I see why your changing them that way, you should of just bought replacement single LEDs instead of trying to remove them.

I don't know what type you need or voltage but this kit probably has it. If you measure the LED you'll know, and what voltage you need

I believe they are measured as, 3030 is 3mm x 3mm and 2830 would be 2.8mm by 3.0mm

might help
