Guide for replacing Hisense 55u7a TV backlight leds

Hisense 55u7a

Hi, just wondered if anyone has stripped down a 55” Hisense tv to repair or replace the backlight led strips?

Hoping to find a guide or video

Mine is the Hisense 55u7a model, but it’s likely there’s a number of other models that will look the same inside

I've got a couple of dark strips which I suspect is the led strips, or just one of the LED’s on that strip, though it could simply be a bad connection on the strip

hope someone can help

Cheers

@seanyboy check something like this video Remember that the disassembly may not be specific for your TV but the steps are very similar.

While you work on your TV, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has the same problem as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.

Hi, cheers for your advice.

I have watched this exact video previously and it’s very insightful - just that it’s link to parts comes up with an error page and I’ve read a number of other remarks elsewhere about the led strips being very specific to individual tvs (even if the same size) and didn’t want to head towards purchasing and strip down without a better idea that I have the right parts first (main home tv)

If I get to grips with a strip down, I’ll be sure to document the process

Cheers

If you can't find out for sure by searching etc, usually the part number is printed on the strip itself.

So just search for the part number.

Yeah, thanks for your reply

I had a feeling that would be the case….. just gonna have to dive in and get it open (best done on the kitchen table…. And when the wife is out….or I’ll be in double trouble!)

Led wise (and from other people’s notes I’ve seen on line), I had suspected they might all be in series…. Looks like I’ll be best getting a full set, then they’ll all match and I’ll have some spares (or for other little led style projects that might pop up!)

Cheers again

@seanyboy that is absolutely correct. You will need strips that are specific to your panel.

Cool, gonna strip it down one evening (when the wife has gone to bed) and get the exact part number

I’ll know what I’m doing at least next time with the strip down when the strips eventually arrive

Fingers crossed

Thanks again to all for your advice
