Trying to set up this model TV to run off of the Wi-Fi to get channels and stuff. I have no idea what's going on in terms of that. It's working in the rest of the house. I just need to do the setup. What would I need to do in order to figure this out? And is it possible on this TV? That might be a fair question. I don't know if it's a smart enough TV.
G: TL;DR:
That TV (Panasonic TC-L42U5, 2012) is not a
smart TV and has no built-in Wi-Fi. You cannot connect it
directly to Wi-Fi to get streaming channels. To use internet apps, you
must plug in an external device (Roku, Fire TV, Chromecast, Apple TV,
game console, etc.) through HDMI.
Your label shows:
That series was one of Panasonic’s budget non-network models. It does not include:
So if you're digging through menus looking for Wi-Fi setup, it simply won’t exist.
You just attach a streaming box to an HDMI port.
Typical options:
| Device | Price | Notes |
|---|---|---|
| Roku Express | ~$30 | simplest, very reliable |
| Amazon Fire Stick | ~$30–50 | good if you use Prime |
| Google Chromecast with Google TV | ~$40 | integrates well with phones |
| Apple TV | $$$ | premium option |
Setup is basically:
After that, the TV just acts as a screen.
There are two common ways:
Apps like:
These run through the streaming device.
If you plug an antenna into the TV’s coax input, you can get:
Then run Channel Scan in the TV menu.
Look on the back/side of the TV for:
Those are the only connections you need.
Many people with older TVs use:
That gives you:
…and the TV itself doesn’t need to be smart.
テレビ（てれび） は インターネット に 直接（ちょくせつ）
接続（せつぞく） できません。
— This television cannot connect directly to the internet.
外部（がいぶ） デバイス を HDMI で 接続（せつぞく） します。
— You connect an external device through HDMI.
If you want, you can also show me a photo of the side/back ports, and I can tell you exactly which cable/device to plug in where.

What about this one? Does it have Wi-Fi?
G: TL;DR:
Yes. This one does have Wi-Fi and is a smart TV. You
should be able to connect it directly to your home network from the
settings menu.
Your label shows:
That means it supports streaming apps like Netflix, YouTube, etc., directly on the TV. citeturn0search4
Using the remote:
Once connected, you can open the LG Content Store to install apps. citeturn0search0
Three common causes:
1. You're in the quick menu
2. TV needs initial setup
3. Wrong input/menu
After connecting, the bottom bar should show apps like:
If you want, show me one photo of the TV screen menu, and I can point to the exact button path to get Wi-Fi working in about 30 seconds.
M: That one would have been perfect, but evidently it's broken in a way that wasn't evident until we tried to plug it in. What is the current generation equivalent of that in terms of size and etc.? It would have been a perfect fit if it hadn't broken, and so if we need to replace it, I want to get one that actually follows all of those specifications, or at least as near to as possible.
G: TL;DR:
The closest modern equivalent to your broken LG 43UK6300PUE
(2018) is a 43-inch LG 4K LED smart TV from the UQ/UR
series, such as entity["product","LG
43UQ7070ZUE"] or entity["product","LG
43UR8000AUA"].
These are basically the direct descendants of the same product
line: 43-inch, 4K, webOS smart TV, roughly the same size and
mounting pattern.
Your broken TV (LG 43UK6300PUE) had these key specs:
That’s basically the standard mid-range LG smart TV format that LG still sells today.
These are the closest current replacements in the same class and size.
entity["product","LG 43UR8000AUA"]
What it is:
This is basically the 2023–2024 continuation of the UK6300 line.
entity["product","LG 43UQ7070ZUE"]
Very similar specs:
Functionally it behaves almost exactly like your old one.
LG’s naming roughly evolved like this:
UK series (2018) ← your TV
UM series (2019)
UN series (2020)
UP series (2021)
UQ series (2022)
UR series (2023-present)So the UR series is the direct generational descendant.
Your old TV:
Modern 43" LG TVs are within about ½ inch of
that.
Manufacturers keep these dimensions almost identical so furniture mounts
still work.
If the old TV was wall-mounted:
So your mount almost certainly works.
Look for:
That will feel almost identical to what you had.
新しい テレビ（てれび） は Wi-Fi に 接続（せつぞく） できます。
— The new TV can connect to Wi-Fi.
同じ サイズ（さいず） の モデル を 選（えら）びます。
— Choose a model with the same size.
✅ If you want, I can also tell you:
Those details actually matter more than the model number when you're trying to replace a TV that fit perfectly.
M: All right, is there anything equivalent from LG that was made a little more recently? We've got the remotes that all seem to work the same way on the different TVs, so we wanna stick with the same brand.
G: Yes — and sticking with LG is actually a good idea if you want the remotes and interface to feel the same. LG has kept the same webOS ecosystem and remote logic for years.
The closest modern equivalent to your broken LG 43UK6300PUE (2018) is below.
entity["product","LG 43UR8000AUA"]
Why this is the direct descendant:
These are essentially the same category and price tier your old TV belonged to, just several generations newer. citeturn0search0turn0search6
LG itself considers the UR series (2023) the replacement for the UQ series (2022), which replaced the UK series (2018) your TV came from. citeturn0search9
Your TV sits in a chain that looks roughly like this:
UK6300 (2018) ← yours
UM6300 (2019)
UN7300 (2020)
UP7000 (2021)
UQ7000 (2022)
UR8000 (2023–2024)So UR8000 = the modern version of your TV.
Your old TV and the UR8000 are almost identical physically.
Typical numbers:
| TV | Width | Height |
|---|---|---|
| 43UK6300 | ~38.5 in | ~22.5 in |
| 43UR8000 | ~38.1 in | ~22.2 in |
The screen size is 42.5″ actual panel, which manufacturers keep consistent. citeturn0search5
So it will fit almost exactly where the old one did.
Your existing LG remotes will usually still work because:
Even if not perfect, the behavior will feel nearly identical.
If the goal is “replace broken TV with the closest modern LG equivalent”, look for:
LG 43-inch UR series
Examples you’ll see in stores:
All of these behave basically the same.
These are usually around:
Which is roughly the same market tier your 2018 model occupied.
43-inch TVs today are mostly entry-level models, so:
This is exactly the same market position your old TV had.
If you want the simplest drop-in replacement:
➡️ LG 43UR8000
It’s basically the closest modern clone of the TV you liked.
If you'd like, I can also show you three LG models that are even closer to the old remote/menus, because LG actually splits the 43-inch lineup into two different internal hardware families, and one of them will behave almost identically to your older TVs.
M: What can you tell me about the UA77 series in comparison to the suggestion you made?
G: TL;DR:
The LG UA77 series is basically the newest
budget successor to the type of TV you had. It’s very similar
to the UR8000-type suggestion, just a newer
2025 generation of the same entry-level 4K LG line. The
differences are minor: updated processor, newer webOS version, and a
slightly refreshed design.
The UA77 (UA7700) is a 2025 entry-level 4K LED smart TV in LG’s lineup. citeturn0search8
Typical specs:
It’s basically designed as a simple streaming TV for everyday viewing, similar to what your 2018 LG was.
Here’s the practical comparison.
| Feature | LG UA77 (2025) | LG UR8000 (2023) |
|---|---|---|
| Generation | Newer | Slightly older |
| Smart OS | webOS (newer version) | webOS |
| Processor | Alpha 7 Gen8 | earlier generation |
| Resolution | 4K | 4K |
| Refresh rate | 60 Hz | 60 Hz |
| HDR | HDR10 | HDR10 |
| Wi-Fi | Yes | Yes |
| HDMI ports | ~3 | ~3 |
| Target market | Entry-level | Entry-level |
Realistically:
Even reviewers describe it as a very basic 4K TV without advanced features like local dimming or HDMI 2.1 gaming support. citeturn0search8
Compared to the 2018 LG 43UK6300, the UA77 gives you:
Improvements
Same core experience
So it should feel almost identical to what you liked, just newer.
The 43-inch UA77:
Your old 43-inch LG was about:
So it should fit nearly exactly in the same physical space.
If you're choosing between the two:
For most people replacing a 2018 LG, the UA77 is perfectly fine and actually the most direct modern equivalent.
If your goal is “same LG experience, same size, same remotes working”, then these are the three safest choices right now:
All behave almost the same.
テレビ（てれび） は 同じ ブランド（ぶらんど） を 使（つか）う と
操作（そうさ） が 簡単（かんたん） です。
— Using the same brand makes the controls easier.
新しい LG テレビ は Wi-Fi に 接続（せつぞく） できます。
— New LG TVs can connect to Wi-Fi.
If you want, I can also tell you one subtle trap with the 43-inch LG lineup that stores don’t explain, and why one of the models is noticeably better even though the specs look identical.
M: On Amazon, the review for the one you suggested is something like five stars average, while the new one is something like three and a half stars. Can I ask you to look online in the discussion boards and something to see if you can find an explanation outside of just the newness making it a little more volatile?
G: Short answer: yes — there is a real reason the UA77 series can have worse review averages than older models like the UR-series. It’s not just volatility. The discussion boards and technical reviews point to three specific causes.
The biggest criticism from reviewers and enthusiasts is low contrast / washed-out blacks.
Professional testing found:
Consumer testing similarly noted weak HDR brightness and limited highlight detail. citeturn0search26
What this means in plain terms:
| Situation | What people notice |
|---|---|
| Watching movies in a dark room | blacks look gray |
| HDR content | not very dramatic |
| Night scenes | flat-looking |
This is one of the most common reasons enthusiasts say to avoid the entry-level LG series.
Example from a TV-buying guide thread:
“The SDR color volume… is sub-par… low contrast.” citeturn0search18
You’ll see a strong pattern on TV forums:
In TV subreddits, people often warn buyers away from the budget models:
“both are essentially the same entry level models” citeturn0search1
Meaning they’re basic TVs with minimal hardware improvements.
So the UA77 being newer didn’t add much performance, which disappoints buyers expecting progress.
These show up in owner reviews:
Nothing catastrophic, but they drag the rating down slightly.
This is subtle but important.
When a TV is marketed as:
“AI processor / HDR / smart TV”
people expect dramatic picture improvements.
But the UA77 is still basically:
So expectations exceed what the hardware can actually do.
The UR series tends to get slightly better ratings because:
The difference is small but visible.
For a 43-inch replacement like yours, the reality is:
Neither is dramatically better.
But if ratings matter to you, the UR-series usually scores a bit higher.
For a 43-inch TV under ~$400, forums frequently recommend:
because they have much better contrast and HDR.
However, if you want LG specifically for the remote ecosystem, then:
UR8000 is usually the safer pick.
テレビ（てれび） を 選（えら）ぶ とき、画質（がしつ） は パネル の
性能（せいのう） に よります。
— When choosing a TV, picture quality depends on the panel.
新（あたら）しい モデル でも、必（かなら）ず しも 良（よ）い とは
限（かぎ）りません。
— Even newer models are not always better.
If you want, I can also show you one weird trick about 43-inch TVs that explains why many of them look worse than larger TVs, even when they have the same specs. It’s one of those things manufacturers almost never mention.
M: The one you suggested, was that the UR8000? We kind of got our ideas switched.
G: Yes — the one I originally suggested was the LG UR8000 series. That’s the model we were talking about before the names got crossed.
To recap clearly:
The confusion makes sense because LG’s naming is extremely similar and the models sit in the same budget lineup tier.
The UR8000 is a 2023 entry-level 4K LG smart TV that replaced the UQ-series before it. citeturn0search3
Typical features:
It’s essentially LG’s standard mid-budget everyday TV. citeturn0search15turn0search21
Both are entry-level LG 4K TVs.
However, testing comparisons show something interesting:
That’s why you’re seeing lower review averages on the UA77 even though it’s newer.
Forums and review sites tend to favor it because:
And importantly:
Since you said:
Then the closest replacement for what you liked is:
➡ LG 43UR8000
It’s basically the modern equivalent of your broken 2018 LG 43UK6300.
If you see any of these model numbers, they are essentially the same family:
Retailers rename them slightly but the hardware differences are minimal.
テレビ（てれび） の モデル は 年（とし） ごと に 少（すこ）し
変（か）わります。
— TV models change a little each year.
同（おな）じ シリーズ なら 操作（そうさ） は ほぼ 同（おな）じ
です。
— If it’s the same series, the controls are almost the same.
If you'd like, I can also show you the one LG model that is the exact spiritual successor to the TV you had, because LG actually split the budget line in two directions after 2023 and one of them is a noticeably better match.
M: As far as the broken one, is there anything in it that discussion boards say are worth saving or scavenging or whatever? I feel vaguely wasteful. Okay, it's more than vaguely. I just always have to temper it, the desire to keep things because I have a tendency to not hoard things, but see their potential for use, even when they're broken, particularly if it's something expensive. But in this case, you know, it's the disposable culture and all of that. I don't really want to just toss it entirely in the trash because the screen is cracked if there's something that could be easily used for another project or something like that.
G: TL;DR:
Yes — discussion boards and repair communities consistently say
three parts from broken flat-screen TVs are worth
saving if the screen itself is cracked. The rest usually isn’t
worth the effort unless you like electronics projects.
Most salvaged parts:
Everything else tends to be niche.
Flat-screen TVs almost always contain small but decent stereo speakers.
Typical specs:
Common reuse ideas:
These are very easy to remove (usually just two screws and a connector).
The power board converts wall AC into several DC voltages.
Common outputs:
Electronics hobbyists sometimes reuse these as:
However:
⚠️ These do contain high-voltage components, so they’re only worth salvaging if you’re comfortable with electronics.
Inside the panel are long LED strips used to light the screen.
These are actually one of the most commonly salvaged TV parts.
People use them for:
But there’s a catch:
You have to disassemble the panel layers, which is tedious.
The internal metal chassis can be reused as:
Not glamorous, but sometimes useful.
Technically salvageable but usually not very useful.
Reasons:
Repair techs usually sell these as replacement parts, but hobbyists rarely repurpose them.
The LCD panel itself.
Once cracked:
This is why most broken TVs get scrapped.
There is a niche hobby where people turn broken TVs into:
LED light panels
Process:
Result: a large flat light panel useful for photography or art.
This is one of the few creative upcycling uses.
If you want the highest value salvage with minimal effort, keep:
Everything else can reasonably go to electronics recycling without guilt.
テレビ（てれび） が 壊（こわ）れて いても、部品（ぶひん） は
使（つか）える こと が あります。
— Even if a television is broken, some parts can still be used.
スピーカー は 再利用（さいりよう） しやすい です。
— Speakers are easy to reuse.
If you want, I can also show you one surprisingly cool project people do with broken LCD TVs that turns them into something worth keeping, and it uses almost the entire backlight system.
