How standardized a lcd panels? Could I replace the controller in a smart TV with one of these HDMI to LCD controllers?
You must log in or register to comment.
LCDs do tend to speak somewhat standardised languages, but there is a lot more to a modern TV than just an LCD controller.
Color and white balance calibration, image/motion processing, HDR Processing, backlight control/dimming zones, input management, audio decoding/encoding/passthrough, digitizing analogue sources, HDMI licencing, Dolby licencing, etc.
If you want a better smart TV the best thing to do is to get a hackable TV like most android based models, replace the launcher, strip out system apps and telemetry with ADB and start fresh, then either leave it offline or use filtering to only allow access to the services you approve.
@Faceman2K23
Do you know a list of hackable tv’s or at least brands?
I’m very interested in preparing for the moment my current tv break.
@HaywardTOh my god this is the most depressing shit. Remember just watching TV?
Not sure if there’s a list, but most Android based TVs can be cleaned and modded to some degree via ADB. If you can access the dev settings in android, chances are you can do a lot to make it better, strip out some google or branded packages, replace the launcher to block OS level ads etc. Projectivy usually works well since it supports input switching on many devices, but it’s still better to do all of this to a separate box and then plug it into a TV that is firewalled/filtered/offline. more control and less to fuck up.
Rooting and unlocking bootloaders is more complex as these android devices dont have normal recovery systems and require a lot of custom drivers to make the video and audio processing work, so it’s not worth going that far.
I wonder if anyone has made a custom rom for TVs, sort like Lineage or Graphene. These panels run Android, so why not?
I have seen some talk over on XDA forums, but since there is more to an android TV than just the basic android OS, it’s a bit trickier without risking losing licences/compatibility/DRM/features.
Some older LG webOS tvs can be rooted and custom apps installed too such as ad free youtube players etc.
Just found some LG business TVs/displays/signage that actually run Tizen. Remember that cool Linux distro that was supposed to take over the mobile world nearly 15 years ago? Well, turns out, it didn’t, but it didn’t it die completely either.
Hopefully those panels are a bit more hackable or more privacy oriented.
Gets even weirder when you see LGs webOS kinda started out as PalmOS
Yeah, I am definitely going to open up my $400 tv and replace the LCD controller with this sketchy piece of hardware instead of, checks notes, just not activating any of the smart features and not connecting the TV to the internet at all.
Until you get a Roku where you literally can’t use the TV without accepting an arbitration clause.
Here’s an idea for you, don’t buy a Roku TV. Visio is pretty much the exact same price and you can just not use the smart features and just connect HDMI.
Yeah but what if you already had one. Or bought one without knowing it’d pull a fast one on you.
“Here’s an idea for you; how about being aware of every single company you might interact with and all the shitty ways they try to screw you over.”
That’s a little crass, but I hope you understand my sentiment.
Also how can such arbitration clauses be both legal and binding, I don’t understand it.
Did you know: you can look up a review of any piece of hardware out there that you wish to buy and gather info on it before making a purchase.
I love looking up reviews for every little thing I purchase, and even when I do ads nor microtransactions ever get patched in at a later date! Same goes for those service agreements which aren’t ever updated!
Oh, wait, no. That’s exactly what happens.
Nor do I want people who aren’t as tech savvy/in the know to get preyed upon/swindled.If you are incapable of sussing out the mindless morons who write reviews from the people who actually know what they’re doing that’s more of a you problem than anything else.
And buying a TV is not a little purchase unless you’re incredibly rich in which case why would you even fucking care. But hey, if you like rolling the dice on your hard-earned money to buy something that’s not going to work the way you want it to and then break it trying to “fix” it with some sketchy hardware from some rando online who thinks they’re “in the know” be…my…guest.
This is such a stupid argument. Not everyone is tech-literate. Ideally people wouldn’t have to look out for this because the practice wouldn’t exist. “Just don’t get robbed/swindled lol, you should’ve known better”.
And no, I’m not trying to advocate for whatever sketchy device is linked above. What I am saying is that I understand the sentiment, because that manufacturers are increasingly encroaching on our ability to own what we buy with parts pairing and always online requirements.
You are an Eloi not a Morlock.
I have rematched controllers to displays in the past. It’s neither simple nor easy. You’ll need to dig through spec sheets to ensure you’re sending the correct signals over the correct pinouts, at the correct frequencies and voltages. Be prepared to read some IO documentation for the sending and receiving chipsts, then verify pinouts with certainty. They are not always standard.
Here are 2 identical LCDs, with 2 very similar, nearly identical looking controllers. Note that one needed to be re-wired. It is not fun butt-connecting 2 dozen 28ga wires.
The in-rush of endorphins when the modded LCD thing actually worked probably knocked you out?
A bit of a side story: I disassemble probably 1–5 panels in a week. (For recycling, it takes about 20-45min per panel.) The flat cables alone are so flimsy, I would say just assembling a display again from known, matched and functional parts would take days. I would triple or quadruple that to assemble a display from random parts. Considering this, that modded panel is quite amazing to me.
In standalone panels, the PSU has a chance of killing you: the main capacitors can hold multiple joules worth of nope, charged to about 400v. So, if the main caps are not allowed to discharge (if they discharge at all that is), there is a possibility of death when disassembling a panel with an integrated PSU. Waiting “5min” is bad; a PSU needs to be unplugged for a day or two at least before the charge drains out.
I’ve always wondered this, figure this is the thread to ask it.
I’ve been using the same dumb TV since 2013 it’s great, but eventually it’s gonna die an I’m scared of what pieces of shit smart TV’s are.
Could I not just use a computer and run it through the smart TV and bypass all the smart bullshit by using it as a monitor?
Some smart TVs require you to connect them to the Internet before you can even use them with HDMI. It’s a changing world. This post has a lot of interesting comments.
Every one I have encountered only requires that for use of the smart TV features. And if you have one that requires Internet just to use HDMI to connect to a device, your TV is 100% spying on you and you should return it.
I don’t buy TVs but I quized the guy pretty heavily thinking that was an option. He seemed to know what he was talking about about. This was an Onn Roku TV.
I would immediately return that crap to the store.
Where I first caught wind of this was in the return line at Walmart where a guy was returning a smart TV because he wanted to hook up to his Dish receiver and couldn’t without creating an account.
Provide the citation please because the last one you mentioned to me was about a return that you heard about while standing in line at Wal-Mart about a rok/tcl tv, which btw which you don’t need to do any of that to use it.

oh and
This makes me want to look at TCL TVs more closely. Thanks.
I wouldn’t recommend any TCL older than 5 years. No idea about new ones but I used to sell and install them and they all just sucked. The video quality was mid and they had a weird input delay that made them annoying to use. These were tvs that were new out of the box.
Just don’t connect it to your wifi. Any TV that has cell service antenna, like most cars now, just don’t buy those.
BestBuy brand Insignia offers non-smart TVs.
My experience with LG/WebOS has been fine if I don’t try to get online. It doesn’t pester me to do so.
I have a WebOS TV and I absolutely hate how slow it is. Turning on takes a long time. Selecting apps takes a long time. Flipping channels takes a long time. Did we forget how fast TVs from the 90s were??
To be fair, TVs from the 90s didn’t have apps, and I don’t actually use the apps on my LG, so it seems fine.
For older LG webos TVs, the delay between button push and action in the settings app can get as bad as 4 seconds.
The reason I bought it:
- Samsung pushed ads agressively on their TVs
- I had an HP tablet with webOS before and wondered what LG did with it after taking over the development. I was horrified.
The hardware is not much better. There’s constantly something wrong. But the LCD panel is pretty decent, so I just patch it up every time, rather than throwing it out.
In Spanish “WebOS” sounds exactly as if you were saying “huebos” which is slang for testicles.
Just a tidbit for your day to go just that much faster.
I have a Hisense and a LG and I never connected them to WiFi. I have not had any issues
No.
Smart TV’s run automatic content detection on all their inputs. You will also be nagged to put the device online relentlessly, and some models will not let you skip internet connectivity.
Which manufacturers specifically will do this? Other comments seem to think LG is ok. Genuinely curious if anyone has experience.
I wish I knew, but the ad industry LOVES this tech: https://duckduckgo.com/?q=smart+tv+ACR&t=ffab&ia=web Every other result is “How ACR is going to be awesome for advertisers/marketers”. the ones in between are “How to shut off ACR” :-/
so far i’ve been between simply buying a projector, im assuming those havent been smartified yet.
Or buying a big format display, i think those still exist, i hope they do at least.
Presumably you could probably mutilate a smart tv to properly disable it’s functionality, but im not electrical engineer so don’t ask me.
Possibly dumb question but can you use a Projector during the day these days?
My TV is in my living room. Right next to 2 big windows. With 2 sliding glass doors across the room
reminds me of this video that shows how they reverse engineered the macbook touchbar display and made their own driver. I bet a tv is harder, but I’ve wondered the same thing, and would be interested to see someone try.
Probably not but you can buy digital signage. You will pay upwards of $4k potentially based on your needs.
Remember when you didn’t need this shit to just watch a movie?
I 'member
Seriously. Go back to the 90s, do this about anything, and Kevin mitnick will vanish from everybody’s radar just about instantly.
Now we need to do this shit to fucking watch TV. I need complex filtering software, anonymization tools, and a signal bounced off three continents to watch a video of a cat climbing into a box. A video that was recorded five feet away from me.
If I want to do it on a TV, I need to start soldering and hope to fuck I don’t touch the wrong capacitor.
and a signal bounced off three continents to watch a video of a cat climbing into a box. A video that was recorded five feet away from me.
are you talking about some proprietary camera that only syncs to the cloud?
No I’m talking about my roommates YouTube videos of their cat.
Jeff Geerling did a whole video about you can just use a professional display. It has the option to install a raspberry pi because it’s meant to be a display for a store window. This would be a good alternative but $$$.
https://www.sharpnecdisplays.us/products/displays/m551
Note: the reason TVs are cheap now is because they collect data about you. Your data is subsidizing the cost. So if that’s the case how much money do they make off you that getting a non smart display costs 4k?
Less than 4k; I remember my last dumb TV cost like 700$.
Just fyi - Your post is 20 minutes old and the eBay link has broken already
I think it depends on what level the smart aspect is implemented and how integrated it is. Screen technology has been getting more and more locked down by corporate privateers/thieves.
I mostly tried hacking on small displays, and finally gave up as it was over my head. There is a whole lot going on in various layers and protocols. My rule would be to only buy a product like this if I can find a functional example of someone using my exact hardware with this exact hack in question.
In my experience, prototyping or hacking around with displays is a losing game because they are not constructed for handling like this. You must go to extremes to avoid placing strain on the flex ribbon connections and must be very careful about taking the thing apart to test with it disassembled. It only takes a tiny mistake to damage something that can not be repaired. They are usually sensitive to small nonsense too. These are fast parallel circuits. I stay away from them, but maybe I’m just being soft.
So, “yes”, but also no. You’ll lose the calibration panel for your display, and the result will probably be unwatchable.
You’re much better off buying a display which is un-smart to start with. These are often called “commercial displays”. Or of course you could just buy a monitor.
Or I could just accept my place and watch the ads and go along with all the caveats like a good consumer. I don’t see that happening.
I’ve looked, and it’s surprisingly difficult to find one with decent resolution in a decent size. It seems they’re all 1080p nonsense.
I’m not even looking for fancy features like OLED or whatever, I just want 4k in >60" screen size without any smart features. Why is that so hard??
What you want is a “commercial signage display”. They usually have all the modern display features because they’re intended to make products look good, and they’re generally well built because they’re meant to be on all day.
They cost more than similar TVs because they’re not subsidized by smart TV shovelware and data gathering.
damn, this is actually a life saver right here. Hadn’t thought about commercial signage displays. Guess that’ll be living rent free in my head for the next decade until my TV shits the bed.
Heh, same. I bought what was probably the last generation of dumb TVs. It’s a 4k 65" panel from a company called Atyme which I believe is now defunct, made with an LCD panel that was part of some other company’s manufacturing order but didn’t pass quality check, and it has like 2010-ish TV electronics (you can tell because the settings menus look just like what you find on all the TVs from that period). It’s 4k but it doesn’t have any of the fancy features like HDR because the electronics are limited… but it also doesn’t have a bootup delay, it just turns on.
I didn’t learn about commercial signage displays until after I had bought it.
mine is a 1080 panel from 2012 consumer electronics era production. 20s startup delay, because i guess counting numbers is hard or something. Gotta love shitty tech i suppose. The 2010s era UI interface is SO real.
Why go through all of that when you can just block network access, or not even connect it at all? Hell, just get a Blocklist that includes the bad URLs for your TV you don’t want it using, and run it on AdGuard or Pihole. Lots of easier ways to work around this.
Why go through all of that when you can just connect the board to the panel.
Why go through all that when you can just build a time machine and go back in time to be in the boardroom when someone presents the concept for a smart TV and then hide under the podium and tickle their genitals to distract them during the presentation and then spend the next 20 years in prison for sexual assault where none of the televisions have smart features?
Well you could not connect it to the internet…
Not anymore with sidewalk and other similar corporate networks bypassing any requirement for the consumer to connect the TV to wifi
Do these show up as networks on devices, or are they kind of hidden? I’ve looked before and never seen any open wifi around my house, but I am near a mall and lots of shopping.
They do not use wifi. They use BLE over short range, or LoRa or FSK on 900mhz over long distances. If you wanted to see them you’d probably need a scanner built specifically to find them but idk if anyone has made one.

“How much of my internet bandwidth does Amazon Sidewalk require?”
“Very little. Sidewalk’s connectivity is distinct from your home Wi-Fi. If you choose, however, to enable Sidewalk on your eligible Bridge devices, those devices would use a small amount of internet bandwidth.”
This sounds like it still needs your internet to work unless I’m missing something.
The connection isn’t for you. It’s so the TV can fingerprint the content you watch, and then send that utilization data back to the company.
You don’t need much bandwidth to do this.
So with no wifi connection, and a blueray player, if you play Star Wars, they can fingerprint a few frames, send them back to Roku or whoever over sidewalk via your neighbors ring doorbell, and know you played star wars… Even with your completely offline setup
Jacking off with a monkey paw while you dream of a mesh network. Thanks amazon.
If you don’t have a sidewalk bridge but your neighbour half a mile away has one, your device will connect to your neighbour’s bridge and send data to Amazon without you knowing
im sorry how is this legal?
Corpo exception.
Also, maybe it isnt; state isnt gonna stop em either way.
correct me if im wrong, but a device trying to connect to the network in order to analytics. Which can’t, which then defaults to a SECONDARY BACKUP mechanism, just to transmit ANALYTICS. Is basically just spying, and you cannot convince me otherwise.
I… Well I might try but only if it were funny. I agree. But its not effectively (and I don’t think technically) illegal.
Seems unnecessary surly just plug in a raspberry pi into the HDMI port and never connect the TV to internet u can probably flash some version of android TV onto the pi and all set.
Am I missing something here? Why in the hell would I try to jam this into a TV, something that’s not trivial btw and more than likely not compatible vs just not connecting the blasted thing to the network? Do they come with cellular data you can’t turn off or something?
Because some people don’t like the bloated ‘smart’ operating systems on their tvs or how they operate. I.e. input lag when pushing buttons, showing ads or other stupid bullshit. Tbh I’d rather have a large stupid lcd panel that just turns on and shows whatever I plug into it via hdmi.
The only alternative to replacing the board are commercial displays, but those are very expensive.
What are you trying to accomplish? Just reset the TV and keep it off the internet.
Many smart TVs require you connect to create an account. More might in the future.
