First thank you for this video. This helped me greatly. Things I would suggest. 1) tape filters more than 1 corner they sled slightly when trying to line up with top screen pegs on reinstall. This created a minor quarter inch dark area at the top left bezel. 2 - I didn't not cut new white card stock for light reflector. I got darken areas around the led strips. Only noticable on pictures with lighter colors or all same color, but still annoys me. Not worth taking it apart now it's reassembled and working. If I was to ever redo I would cut new cardstock to fit around each led and patch it in with tape. I understand reason for cutting it as it would be near impossible to get all 5 strips in exact placement for paper since it would have to match opening for plastic led covers. 3 - ribbon cable connectors on mine the brackets lift up to release at least on my tv. 4 - I reinstalled bezel screws before flipping tv back over on reinstall that seemed safer than waiting until the end. Overall I'm pleased with my $40 fix. Once again thank you for this video.
Follow up on this repair, can totally see the cut outs of the reflector when watching bright or dark videos... I figured between the diffusing lenses and the filter sheets that it wouldn't matter but it does. Don't cut out the reflector sheet people unless that doesn't matter to you. Also, if you are changing LEDs on the bars, make sure your diffusing lenses is completely centered and flush when re-adhering it to the bar.
I wonder if after you are done if you had stuck back the pieces you cut with the double sided tape would it eliminate that issue..... at the very least I would think it would minimize it...the effect..
@@bzashadows did that eliminate the problem of seeing the cutout? would you suggest another way. I believe this is the repair i will need to do. wont know 100% till me tv led tester is here but the tv has virtually no backlight and is stuck in a boot loop. thanks for your time
@@jasond2831 I kept all the cut out scratches of paper so I just stuck them to the LED bars with some sticky tack, but any adhesive would work; that fixed the cutout problem. My biggest problem with this TV is the LEDs slowly have been burning out one by one so ive had to take this tv apart multiple times now and the replacement leds are not the same color as the original so it is noticeable regardless. overall it doesnt ruin the tv watching experience but it is noticeable if i really look at it. This tv was defiantly designed to die early, planed obsolescence and all...
I have a question I got it all apart replaced the LED's thanks for helping with that. But now one side of my screen is darker than the other. All the LED's are lit up and working. You can see the screen it's just everything is darker just only on 1 side. Any idea why?
hello I have a samsung un75100af, it was working fine for a few hours and then from one moment to the other it began to turn on and off with a clicking sound. what part do I need to replace
I had a bad led strip. Bought all 5 replacement strips from ShopJimmy and put it all back together and now I have a jagged line down the right side and no picture. Any suggestions on things to check before I toss the tv in the trash?
the ribbon wire connecting the tcon board to the long boards taped have probably lost connection. make sure that the ribbon connector is fully seated inside of the tcon seat.
I believe you might have messed up the ribbon connectors that go to the screen... If you still have/had the Tv you could check by wiggling each one if it solves your problem then it's one of the connectors unfortunately these are not fixable....so if it is that it's trash...
Think never do is cut the reflector like he do .. this is not a professional job at all and you serve your clients a tv like this with in pictures some zones darker than other ?!!
Because this model uses so much adhesives behind the reflector that you have a higher chance of ripping it than getting it off. I was working on a similar model and trying to get this off. When watching this video, I was like, why didn't i think of that. Genius!
@@jorgesilva4440 yeah, that would probably work too. Ive already cut mine out tho. I anticipate having to change more smd leds in the future so it's fine for me but if working on a customers tv, better to try your methods.

I have a fairly new Hisense that just died, no pic or sound just red light blinking,what could it be,I did all the unplug stuff & remote stuff but nothing,main board maybe,seems to be a problem with these junky tv's
Hey I'm having the exact same issue. I ended up asking on reddit. Someone there said with Hisense TVs they go into a shutdown mode when bad LEDs are detected. You can test this by hooking a meter up to the led lead off the power board and measuring voltage when you turn the TV on. Mine went up to 220v DC then slowly dropped back to 0v. I don't know for sure but I assume the board is detecting there is an open circuit (infinite resistance) which is replicated when you disconnect the LED lead and test
@@billwithadart Theres nothing when I hit the on button,dead,I have the back off but to get to the LED's I have to take the screen & framing off so with just what I see with just the boards exposed I dont know which is the led wires.
@Joe Hiatt look for the board that the wall plug connects into. The led lead is small and has 2 wires, should be a red and a black. Mine also said XP702 next to it
@@billwithadart Have 2 ribbon wires on bottom that go into a smaller board ,the others go to speakers, theres a red/white that plugs into the power board up top with a tag #hh1214709 that goes into where the led cavity so probably it,so how do I check with my meter ?
@Joe Hiatt yep that's it. Unplug it and test the 2 terminals on the board side. Plug TV in and check voltage when you turn it on. Should see it rise up to 200 then fall which I guess means leds are bad, idk tho I'm just some guy on the internet
Replaced both boards & nothing,I took a flashlight to the screen in a dark room & I can see the Hisense logo going on & off ,so dont know now if its the LED's or the little boards at the bottom,these LED tv's are junk, many are rebranded junk & there seems to be endless problems with them,they are ticking time bombs
🤦🏾♂️ Feeling a bit bummed out. Went thru the steps and it ended up not working for me. Still just getting the blinking power light twice and no screen turn on. Wasted money on those LEDs.

Thanks for the detailed and easy to follow video! My TV now works again.

they dont know what they are doing they never play the tv when finished

@@carlosk8103 yes, i bought some sticky tack and used that to stick the cutouts back onto the LED bars.

How you know that was the bad led ?
I bought this tv for 269 buks and had to get the 30 dollar 4 year warranty.the pic is very good.walmart had a bunch at this price
I have a question I got it all apart replaced the LED's thanks for helping with that. But now one side of my screen is darker than the other. All the LED's are lit up and working. You can see the screen it's just everything is darker just only on 1 side. Any idea why?
Please answer this question!!!!!!! I have the exact same issue!!!!!!!!!!!!!!!!!!!!!?????????!!!!!!!!!!!!
Dim/bad LED strips that you installed.
hello I have a samsung un75100af, it was working fine for a few hours and then from one moment to the other it began to turn on and off with a clicking sound. what part do I need to replace
So where is the LED driver on this TV? The power supply board?
Looks exactly like the Skyworth I just picked up to repair.
I took off the whole paper stuff instead of cutting . It took some time because of the tape. But it looks fine when I reinstalled.
Is there some sort of trick to removing the power button? Mine is stuck and I can't seem to pull it out.
i had to use force and wiggle it
Great Video. Thanks.
Can I send it in to you to replace it, I work all the time and the time I do have is spent with my lawyer

What's the Level of Patient required to perform this job ?
100 percent,,, I just tried it and omg!!!!
thank you!
What are you doing? Why don't you take off the reflector? This is not a professional job.
Because this model uses so much adhesives behind the reflector that you have a higher chance of ripping it than getting it off. I was working on a similar model and trying to get this off. When watching this video, I was like, why didn't i think of that. Genius!
@@bzashadows If you use a hot air blower, if you don't have a professional you can use it to dry your hair. Removes well and gets a more elegant job
@@jorgesilva4440 yeah, that would probably work too. Ive already cut mine out tho. I anticipate having to change more smd leds in the future so it's fine for me but if working on a customers tv, better to try your methods.

@@jorgesilva4440 yes they just do a half ass job you know tv repair made easy
I threw away the paper. Now I see a bunch of blotches on the TV. Huge mistake!

thats more than likely the backlight leds.
I dont change one strip i change all of them

Mine does that too…bought a new power supply board..still does it…thought about doing this now I know not to..thanks
sounds like the bios chip
❤️
first?
Some time between the time this video was made and the time I tried this they decided to glue and tape everything
