There is no way to turn off the WiFi. So WiFi will keeps broadcast everyday. Not good for people in front of TV. Chromecast has choppy audio issue when cast from computer.

Excellent TV and value

This is a great 4K TV for the price. Sure, there is no Bluetooth even though the site here says there is for some reason, but the picture quality is excellent on anything from the news to HD rips of Planet Earth II, and Google Cast is quite handy for those without a PS4 or streaming device for watching YouTube videos, etc. I haven't tried out the true 4K capability yet, as I don't own any BluRay. My only real complaint is there is no RCA output, which means that you can't connect a stereo receiver unless you have a one that has HDMI or optic inputs. This was kind of disappointing given that the TV's speakers are awful (as most of them usually are) even though they hype them up in the description. Thankfully the work-around I discovered was to use a 3.5mm to RCA cable which is plugged into the headphone jack on the TV and then into the receiver. A bit odd and annoying that it has to be done in this way, but the sound quality for my Polk bookshelf speakers is fine.

Love ❤️ this tv

Great picture qualitie and sound, very easy to set up, I would give this product a 5 star rating.... however it is not exactly as described. The specs for this tv indicate that this tv has blue tooth technology. This is true, but it's only use is to connect the built chrome cast to ur tablet, phone or iPad. The blue tooth dosent connect to any other device. Over all though. This still was a great buy, and I am happy to have it :-)

  • from Montréal, QC

Great product

for the price, the simplicity of use and the image / sound quality! Google cast is a very useful feature, haven't even had to plug in an hdmi to watch content yet! great buy

  • from Calgary, AB

Great TV and great price

Compared to other TV's with the same features, this TV is excellent. Love the built in Chromecast and ended up buying a second TV.

  • from Revelstoke BC

Fantastic tv

Beautiful picture. Super slick. Very light. Did not buy for Google Cast feature but am pleasently surprised by the feature.

  • from Ottawa, ON

One of the best

That tv has very nice picture specially when playing games i like it and all my kids and there friends

  • from Mississauga

Great Quality for a reasonable price

Have to say wasn't expecting to get a 4K TV of this quality within this price range. The TV offers great colour contrast and is relatively simple to use with the google cast app. It doesn't offer the same colour depth as Samsung or Sony counter parts but it doesn't carry the same price tag either to be fair. All in all it's probally the best 4K you can get in this price range!

  • from Pickering, ON

Very Pleased

I'm very pleased with the quality of this TV. It up-scales HD to provide a crisp picture. There is very good depth in color and contrast. I don't agree that the TV is "Smart" by the general definition. A real smart TV requires the Android TV O/S, not streaming through a phone or tablet. Overall though, I bought this TV to watch TV, and it does tis very well.

  • from B.C.

Smart tv?

Don't buy this tv thinking you are getting something that you can use Netflix with easily. You have to use google cast through your phone. No apps on the unit. The whole reason I bought this "smart" tv was to avoid buying a second Apple TV or a blue ray player with all the apps on it. The picture and sound are great no complaints there, but a misleading label of smart tv when it doesn't operate like one isn't very cool.

  • from Montreal

Good balance

Nice TV - good wifi connection, decent display and sound quality for the price.

  • from Morden, MB

Not User Friendly!

Can only be run through a Device, like a cell phone or tablet. Picture was clear, but when watching sports the screen shrunk to approximately 36 inches??? Not fun for anyone over the age of 10

  • from Calgary, AB

Great TV!

I just bought this TV on sale. The biggest feature for me was the built-in Google Cast (Chrome Cast). Having this integrated makes streaming so much easier. Still fine tuning the picture, but so far absolutely delighted with this purchase.

Excellent TV

I have purchased this last week for my brother. The quality is superb! No overheated symptoms like SamSung. I switched to Toshiba!

  • from Burnaby, BC

Absolutely Love it

With the 43" D-LED backlit screen with LCD display technology, it gives a stunning quality picture and awesome resolution for games.

  • from Ajax, ON

great tv

really nice clear 4ktv just make sure if you're using it for 4k gaming, please remember to connect the tv hdmi cable directly to your PS4 or xbox one s console to get the full 4k by using the remote going to options and selecting HDMI INPUT MODE 2! dont use and external AV boxes in between the xbox one s or ps4 pro console and the TV!

  • from Calgary, AB

love it

no complains

  • from West Vancouver, BC

Overall quite pleased

I purchased the TV as a replacement for an older 40" unit that was dying. Overall, the picture quality is excellent. In regards to a previous review, I also did not find a Bluetooth setup menu item but when I went to use the Chromecast with my iPad, the Bluetooth connection to the TV worked for the setup. It seems that is the only Bluetooth function that is mentioned in the manual which did take a minute to locate using Google.

Toshiba 43" 4K Ultra HD LED TV (43L621U)

Really nice!!

  • from Nelson, BC

Great 4K! Great deal.

At first I got a defective piece but after replacement which took as little as 4 days because I didn't have Best Buy in my town. Now it's been almost 15 days I've been using this tv the service from bestbuy was amazing and the tv is a charm for its price. The sounds is impressively loud and the picture quality is really good. Perfect for watching Netflix and sports. I also use it for gaming purpose with my PS4 it has no lag at all. Also answering Evans Review: Bluetooth in TV is used solely to find your phone to pair it after which you can cast things on television. You must have an app called "Google Home" which would allow you to set up your cast. Great tv, great 4K amazing service from Best Buy and geek squad.

  • from Thorold, ON


Sorry i just saw the ridiculous one star review of the dude who somehow cant figure out how to work a simple tv, its called google, use it instead of complaining to other people to do it for you. Im probably going to buy this T.V

  • from Montreal Quebec


Great TV for a great price.

  • from Lachine, QC


To Evan.... I've spent 5 sec on google and found the manual o.o Copy/paste this on Google : Toshiba-43L621U_15-0970_WEB_V1_EN_Final_lr.pdf It's not clear if the TV support bluetooh, it only seem to be used to setup the integrated Chromecast device See manual page 49

  • from Oakville, ON


Dear Best Buy, I was considering buy this item, or another one from your store. However, I'm having second thoughts about both ideas considering your lack of response to what appears to be a legitimate customer query made as far back as August!

  • from Victoria, BC

Great Entry into 4K

Great picture and the Cast feature is super awesome

  • from Toronto, ON

Picture quality good, but wifi does not connect (yet)

I bought this TV at the beginning of September, 2016. The picture quality is good. When I tried to get the TV to connect to my wireless router, a message came up that the connection might not work in 'your country' or something similar. After about 5 or 6 unsuccessful tries, I called the Geek squad, since I had paid for an extended warranty. After an hour on the phone with a GS person, no remedies emerged. GS person said this TV does not work with 5G, but my router has both 2.4G and 5G. No one really wants to spend 2 hours trying to get a TV to connect to wifi. If you have more success, please let me know the secret. So, the TV is good. The wifi connectivity does not yet work. The GS was disappointing.

This cast thing is retarded, if u dont have a phone or forgot it somewhere then ur not watchin anything!!! U need ur phone!! N who wants to use their phone when u need it for better things like phone calls n facebook lol...get a smart tv with the apps built right into the tv ..where u can actually use the remote!!

  • from Mississauga, ON

Excellent Option

The TV is excellent. the only thing that I disliked was not having an option for smart streaming like you tube and Netflix. You will always have to use Google Cast with an android phone that is not always practical. Had to buy a Roku to convert it to a Smart TV

  • from Valley

Worst TV Ever

We purchased this TV during the VIP sale. No manual No support does not exist on Toshiba Support site Geek squad no assistance TV turns on every morning at 5:30 AM TV has no Timer Geek squad says it has a Ghost Warranty support says no record of sale After a week on its way back

  • from Toronto, ON

its going back!

The TV is quite thick - about 3.5 inches - and has an unattractive side profile so this should not be mounted on a short wall that anyone will walk by. Also the remote has no smart functionality; the only way to use the smart functions is to cast from another device like a phone or computer using Google cast, potentially limiting your signal strength. As well, it means every user needs to download the Google cast app to their smartphone which, for a guest bedroom TV, is completely unsuitable. Also in this size we did not notice the difference between the 4K and our old 1080p at all. Taking this back tomorrow to find something slimmer and more practical.

No manual or bluetooth as advertised

The instructions inside say to go online to view the manual. Great but the model doesn't exist on their website. Also the specs say bluetooth (what I was looking for the manual to see how it's enabled) but I do not see any way to turn it on from the settings menu and bluetooth devices scanning do not find it. Bestbuy, what would you like to provide to me for this false advertising (online and in store) if it does not actually have bluetooth? I will change my review to the tv functions itself once this is resolved.
