Hi there, this is my first post here since I've just purchased 55" R646 from Dailybasis. Initially ordered C825 but seller did mention its Japan spec then I ran into this thread and read all the hardware mismatch. I changed the night before delivery and seller helped me through the changes.
TV came in generic TCL box with R646 sticker on the side. Box is sliding upwards like reviews in youtube. After turning on I was expecting an Android(crippled tcl) but it is running Google TV Android 11 with google keyboard! Able to login google account and download apps from the store. All tv picture settings works as it should (fald, motion control, etc). Came with US 2 pin plug but 3 pin cable can be used. On Netflix it will run Dolby Vision and Dolby Atmos, popup will come out and Dolby Vision picture settings can be tuned (not accessible when not playing dolby vision videos). Youtube can play HDR 10 and popup will come out.
Its running on MT9615 on platform MT5889 which is A73 1300mhz (C825 is running at 1600mhz) G52 GPU, 3GB RAM and 32gb internal storage (22gb usable). As with backlight I've tested, it has 128 zones (16x8) but specs online said 240 zones which I believe inside their largest screen 75" (20x12?). On the back of the tv theres 2 hdmi 2.1 (4k 120hz) but I dont have PS5 to try them. Rated power is 260W while from BestBuy photo shows 65" running 340W.
The black is black, darkest black similar to oled no such thing as grey screen. For about $500 more you can buy C825 but it is running android 11 at the moment, not google tv. Google home and voice control works, 3 dots will light up infront when you say ok google and you can turn all the lights off in the settings.
My only gripe is that it does not come with the new remote RC902N with side volume. Instead the old RC802N was given and i think this is normal for supplier that they take the ori remote to sell seperately and make more profit?
The only reason I choose R646 over C825 is because it is shipped with google tv instead of waiting for updates for C825.
I hope this helps. Let me know if the tv I got have different specs than listed online so far I think it is very similar.
I have no permission to post photos but can dm me and i send you the Aida reports.
