I have this love/hate relationship with my Hisense TV. Lucky for me, this TV made the relationship status easier by breaking about a week ago. It got replaced by a TCL P635 Google TV, which is perfect for my needs.

I took the Hisense to a repair shop, to see if I can fix and flip it, alternatively, there are some shady characters buying broken TV's, either for parts or to make Nyope (as my mother believes). Quote came back - R2000 to fix the TV. Now, paying 2k to fix it and maybe getting R2500 for it second hand does not help subsidise my new TV enough. I asked the guy to not proceed with the repair. Yesterday, I drove to the shop to fetch the broken TV, with a crafty plan of asking for a fault report (since I am paying a fault finding fee), with which I can probably get somebody else to fix it, maybe cheaper. Got to the shop, and the oom told me that they had already fixed it, and would need to remove the new parts before I can take it, since I don't want their fix. Yes - we fixed it, but give us time to break it again, then you can come fetch it.

Turns out, the backlight(s) were faulty. So, I started googling a little - you can get universal LED backlights on Takealot for under R500. Has anybody done this fix themselves before? I know nothing about soldering, etc, but the ones I saw take plugs. Can anybody guide me to a nice tutorial or something? Should I not try this myself at all?

How old is the TV? Remember Hisense has a 3 to 4 year warranty.
 
I've seen these universal replacement led strips.....the job can end up in a real mess if the person doing it doesn't really know or care what he is doing.

Most times the white reflecting plastic sheet needs to be cut to allow the individual LEDs to shine through. So you end up with something that is full of extra holes etc.

Also, you need to be sure about the individual LED voltage. Is it 3V or 6V?

Also, those strips are expensive and most times more than one strip will be needed to get the backlight working again.

Best left to the guys that do this for a living. They will normally replace individual LEDS by desoldering and replacing the faulty one's. Much neater.

At this stage, warranty would probably be voided, since the repair shop has already worked on it, also I have no idea where the receipt is. TV is 4 years-ish old. 43B7100UW, no longer in production, has been k4k from the start, as it is a Vidaa TV.

You are doing a decent job in deterring me from trying to fix it myself, thanks. Will ask some of the engineer types in the office if they would like a crack at it. Sure as hell not paying 2k for it, though.

If it was bought from places like Makro they keep the receipt, also if you registered it with Hisense you shouldn't need the till slip.
Sadly the 7100 series was entry level and shouldn't have had Vidaa on it :-(.

Nothing should have Vidaa on it. I will not buy toilet paper with Vidaa on it.

Does depend on the version of Vidaa, but the lack of support is annoying yes

Will, the TV seemed great in the store - 4k smart tv. It did not have bluetooth connectivity, and it think it is Vidaa 2 or vidaaU, which means in somebody's opinion, this was an upgrade on an even worse version of Symbian for TV.

you should look for the invoice - those older Hisense TVs had a 5 year warranty - the newer ones have a 4 year warranty - the shop tells you two years then you can register a further 2 online BUT funnily enough i had the backlights going on mine but with it being only one and a half years old i sent it in for repair - and the techie that came to pick it up told me that they honor the 4 year warranty for all of the newer models anyway whether you registered online or not ..... and they also told me that all they had to do was replace the backlight to repair it

But around 4 years back they were giving a 5 year warranty for most Hisense models ...... where did you actually buy yours from - if they remember you they could help by booking in a repair or if it was from Makro you could use the card for them to remember it and give you a printout of the invoice - most places would have asked for your TV licence at the time so they could easily trace your invoice in their records and maybe give you a copy anyway - to be honest though they did not ask me for the invoice anyway - they just came and picked it up, though the shop i bought it from booked it in so i don't know what they ask you for when you book it in yourself online

I bought it from Pick n Pay Hyper, if I remember correctly.

Problem is it's already been worked on. Warranty now voided?
