Hisense 75M7000UWD Dead Pixel Advice/Discussion

Hi All,

I recently bought a Hisense 75M7000UWD in this deal.

I've not had the need to purchase a new TV (or monitor for that matter) for around 8 years, and I guess I had assumed that that manufacturing methods would have improved over the years to the point where dead pixels would be a thing of the past.

However, the first TV I had delivered had 3 dead pixels and as well there was a small gap in the top frame of the TV where some light from the LEDs inside was visible. Anyway, JB swapped it for a new one which I have just received. This new one has corrected the frame issue, but unfortunately still has one dead pixel in the top centre portion of the screen.

The options I'm considering are:
- Stick with the TV I have now and (try to) forget about the dead pixel. I say try to, because the pixels are actually pretty large on this size TV and it's noticeable from a reasonable distance away. Unfortunately I'm struggling with my anal retentiveness and my eye wanders there whenever I get close enough to the TV and it may just drive me crazy before I can forget about it.
- Try for another replacement from JB and hope for 3rd time lucky.
- Cut my losses, return it for a refund and try my luck with another brand/model (obviously most likely at a higher price, but with the potential benefit of improved mental health).

Has anyone else experienced problems with dead pixels on these TVs and if so what did you do?

Have I just been really unlucky with two duds in a row or do a large percentage of these TVs have quality issues?

On the one hand I feel guilty for returning such a large piece of equipment over such a seemingly small issue, but on the other hand I'm kind of annoyed that Hisense didn't perform a bit of quality control up front and eliminate these panels and just sell me a TV that is free from noticeable manufacturing defects like this.

Thanks up front for any inputs or advice.

    8 million 294 thousand and 400 pixels and you're complaining about one dead pixel?

    I'd just ignore it personally.

      Im curious…
      Where did you get that number from?

      • stratbargain on 19/03/2017 - 09:26

        The resolution of a 4k tv is 3840 x 2160. Multiply the two and you have 8,294,400

          Haha now I realise how stupid I am sorry

  • resubaehtgnolhcs on 04/03/2017 - 00:33

    Don't most TVs have an acceptable range for the number of dead pixels (usually based on the screen size)? This way they can say that one, two, even 3 dead pixels are acceptable on a screen given its size and the million of pixels that the screen contains.

    If JB are willing to give you a refund, then cut your losses, accept it, and try your luck with another brand. Once you see a dead pixel on a screen it's hard to forget about it and not notice it again!

    Did you read the warranty for your Hisense TV?
    "this Warranty does not cover (…) defective pixels in the Television where the visible number of those defective pixels is less than or equal to the acceptable number of defective pixels stated in the manufacturer’s specifications (or where there are no such specifications relating to defective pixels for the Television, there are less than 12 defective pixels), it being acknowledged that a normal limitation of the technology for LCD and plasma panels (and the associated manufacturing processes) is for the screen to exhibit some bright, dark or partially lit pixels".

      I did see the Hisense warranty, but I don't give it much credence because they only tell you this after you have opened the TV. Selling a product where the primary purpose is for a visual display and then later claiming that defects in this function aren't covered under the warranty seems pretty low brow to me. If they were serious there should be a sticker on the box seal saying something to the effect of "This TV may have up to 12 defective pixels and we won't replace it if it does. Do not open this box unless you agree."

      Also, manufacturers can try and exclude whatever they want under warranty but that doesn't mean it is necessarily valid under the Australian Consumer Law.

      • derek324 on 04/03/2017 - 11:47

        The Australian Consumer Law is vague here. There are manufacturing ISO standards defining how many dead/stuck LCD panels pixels is "within manufacturing tolerances", or "within specs", and thus can not be considered to be a fault. Most (I believe all) TV screens warranties are similar. Various "zero faulty pixels" warranties (mainly computer monitors and notebooks) are very rare, done for selected premium products only. Kogan policy appears to me to be uniquely generous, I did not know that.

        No manufacturer of any goods is going to advertise on the packaging anything negative - they typically disclose it in detailed warranty online or inside the box. Example: I have never seen a fridge with a label warning: "this device will stop operating properly and may fail if ambient temperature drops below 10°C" (very few people are aware of that, actually).

    In all honesty, I am amazed they even refunded / exchanged over 3 dead pixels
    Yes they are annoying and once you do see them they can never been "unseen" but this unfortunately is the limitation of technology and TV brands that fall in the "lower tier" of the price market, although Hisense is a good brand the batch of TVs at the store may of not been tested 100% or perhaps had failed panels, you could try again and hope third time lucky, although one pixel might be the best chance yet, can you boot one up in store and check it out before taking it home, surely the store would let you do this to confirm its all good before you travel home to find out its not

    Defects happen, its the current limitation of LCD technology, you won't get around this fact ever, even expensive brands like Samsung, LG and Sony have had the same exact issues, panels are all made with the similar technology, stuck / dead pixels will happen from time to time,

    Depening on where they are, they may be "stuck pixels"

    There are video loops that can try and remove the issue, have you tried those loops, or even better yet, gently massaging the affected area with a lint free / scratch free cloth, I have fixed many apparent dead pixels by giving the screen a gentle touch and circular motion to massage the pixels, obviously doing this gently
    might help the situation, it may not as well

    • slackarse on 04/03/2017 - 10:47

      I'm talking about dead pixels here, as opposed to stuck pixels, which as far as I'm aware cannot be fixed with any of these methods.

      I never actually considered that JB wouldn't replace it under warranty, as according to my understanding of the Australian Consumer Law, goods sold must be free of defects. I don't see that a manufacturer or retailer could legitimately say that dead pixels in a television are not a defect. Even Kogan, who seem to get bagged quite frequently with regards to warranty etc., have a policy that dead pixels are a defect that is covered under warranty.

      • resubaehtgnolhcs on 04/03/2017 - 11:18

        Ok, so now you know that manufacturers can consider some dead pixels as part of the course for the technology they employ in TVs. Will this now stop you from purchasing a TV sight unseen, or will you employ some other method (like suggested above), to ensure the TV you purchase is free of dead/stuck pixels?

        1 dead pixel out of 8 million by any means would be considered a very minor defect - and yes, I understand that aesthetically this is not pleasing, but on the grand scheme of things it doesn't alter the overall product or the functioning of said product. 1 dead pixel out of 8 million is an error rate of 0.00000012%! To give you an analogy, it's like buying a pair of expensive runners or an expensive suit, and a stitch/thread is out by a millimeter. This wouldn't affect the overall product and it would still function as stated and intended.

        As I mentioned earlier, if you can get a refund, do it and move on. But just know the next TV you purchase (if you do decide to purchase another TV now that you know the limitations of the technology), don't be surprised that it has a dead pixel or two, or even none!

          OMG, went to the beach today and a grain of sand that was there yesterday was gone. lol

  • havebeerbelywillsumo on 04/03/2017 - 16:21

    IMHO location also comes into play, if the offending pixel is near mid screen then it is way more annoying/faulty then near the edge. Depending on location you may be able to take this further.

  • ChurchMouth on 20/03/2017 - 15:35

    Agree that it depends on the location and clustering.. I have 2-4 bright white pixels "stuck" or "dead" on my hisense, and against any black image it is painfully apparent from 3.5m away. Other smaller dead pixels on close inspection I cannot see from afar. Going to try warranty with TGGs.

    but on the other hand I'm kind of annoyed that Hisense didn't perform a bit of quality control up front and eliminate these panels and just sell me a TV that is free from noticeable manufacturing defects like this.

    They do, it's called Sony, Panasonic and the other big TV brands.

    Really what do you expect from a low end cheap tv? You have a cheaper panel, less R&D, reduced quality control and so forth. You can't have your cake and eat it as well.
