Just made I lead for 240v tv to run on 12v cheers for information all working on 12v now happy days😊
Thanks glade to know this Vlog is still helping out. I have just made a new vlog on this for my new van. Much cheaper than the 12v camping TV's :)
you sir are a legend i was looking for tv for my camper van convertion and was looking at 16" to 19" due to the cost of them been 12v 300 to 400 ect you have just saved me a lot of money thank you so much im going to subscribe :) will watch your other videos to
thank you, its definitely a lot cheaper than the camper van TV's
Great informative video. Considering I'm planning my van build soon, this will be really helpful. Thanks!
Great good luck with the van build
I am so grateful, This is so awesome.... I knew something like this could be done only I didn't know how to pull this off until now. Me and my family appreciate you.
That's great to know it helped. When you buy the 12v - 19v DC - DC converter get the 5 A one. I tried the 2A one and it is not so good on my 24" TV. Been using ours for some time now with no problems
@@BrackstonesTravelAdventures Gotcha, Thanks so much for the additional advice. You have no idea how much I appreciate that.
@BrackstonesTravelAdventures look for larger TV, the 32" inch. They sell 12v size 24" TV now but the 32" are extremely expensive
Great video on how to convert 120/240 volt AC TV to 12 volt DC!
Thanks
A pawn shop would be a good source for a used TV that would work great in this application as well. Great job, thank you very much for the help with this.
Yes it would do some of the older TV do not need changing they may work on 12v. Only reason we went new is for the apps like Netflix and being able to play movies through usb
@@BrackstonesTravelAdventures I'm lurking around in the Tube for ways to make camping in my Astro more enjoyable. Your video was a huge help in answering a couple questions I had. Glad I found it. Thank you.
@@AraceaeFanatics that's good to know hope you have good year travelling
Great informative video. Will be going this a go. Thank you 😊
Glad it was helpful!
i run a 27 inch older tv direct to 12v it cost me 50 quid and works great. another tip is to use the eco mode and lower the brightness to lower the current draw and to make your batteries last longer
That works on some older tvs new one normally run on 19v now but both work great on 12v we have had ours for over 6 months with no problems now
So you just cut the plug off and connected the wires strait onto the car battery mate ?
@@harrynorman2932 The TV runs on 19V dc so a DC-DC inverter is needed. If you go straight onto the 12V battery without the higher DC battery the TV will not run properly if at all
Tv works fine. I leave it hooked up to 12v live, permanently. No dc to dc inverter needed. Its rated originally for 19v dc, i have wired in to my battery bank (with solars) which is 12v dc, works a treat
@@smitmk3 Was this on a smart TV, if it is does it run all ok using on Demand without shutting down. Normally with on demand and apps like Netflix the power usage is a lot higher so will need the converter. Without apps and on Demand it will run all ok as you have seen without the converter. Also what model number have you used so others may buy the same. Thanks for the info and comments
Just wired up my 24" smart LG via the 12V to 19V stepup transformer and it works perfectly. Thanks for the video.
Great glade it worked. We have been using ours for few months now with no issues.
Doing the exact same with a 32" LG computer monitor, has the same 19v barrel plug and has been working great powering off the 12v DC/5525 barrel plug on my bluetti Eb3a and it works great!
Great i thought it would work on the 32" and any size as long as the input voltage is a DC voltage
@@BrackstonesTravelAdventures I just got an eco-worthy 12v 20ah lifepo4 battery from amazon that actually has a DC 5525 barrel plug built into it and was able to do the same. I'm thinking since the monitor is 19v @ 3 amps (a little under 60 watts), as long as the battery is capable of outputting 12v @ 5amp (also 60w) it will work. Basically your theory of it increasing the current draw to make up for the lower voltage seems to be correct! I've never seen a small 12v battery that comes with a 5525 barrel plug built in I was able to get an adapter to power my portably 12v fridge off of it as well!.
suuppeerr..!!!genial thank you brother!!
Thanks for comment. Year on my tv is still running good
Nice one ! 👍🏻
Thanks ✌️
Nice vid. Your neighbour Canada
Thanks for watching! hope you get it working over in Canada
Thanks for the video. My LG tv 55uh600V has just a mains cable connection, but I heard sometimes these TVs might have a 12V socket directly on the PCB inside, so I’m wondering whether to try opening it up to have a look. Just seems risky as my wife will kill me if I somehow break the TV! 😂🤣
Hi, that's unfortunate that the TV has 240v straight in. What size TV is it. If it's 22" or less then it is most likely the voltage is dropped internally by a transformer. If you are not competent and knowledgeable in electronics the I would not take the back off. You could damage the power supply to the TV or burnout the PCB or even hurt yourself. My demonstration was for 19v TVs. Good luck
No no just open it easy job bro😀
AWESOME info and video. Will this application work on a 24" LG smart tv? This is SO trick and I thank you for your time you've taken for the video and replies!
As long as its a TV with the 19v power supply to it. I expect it will be, you can try check online or buy the TV from Amazon or Argos and you should be able to return it is it does not have the 19V power supply. For the DC-DC converter remember to get the 5A one from ebay for a 24" TV
Thank you!
Glade it worked for you cheap way to get 12v TV running. We have been using ours for a few months now
@@BrackstonesTravelAdventures I still haven’t tried it but I’m keeping my eyes open for a TV I could cut apart! Lol
@@7SeasVans no need to cut anything. Just adding a different power supply
Just did a painstaking crawl through the Sony website. These are all their 32" models that take 19.5V. I'm currently looking for a replacement for my KDL-32RD433. Thought someone else might find it useful.

Are these all convertible? im after a 32 inch telly
Only TV's with the 19v power supply input can be easily converted. Not all have this some have 240V into the TV and it is they transformed down inside, I would not use these. If you can get to a shop to check the TV or if you can see the specification and it says 19v inout then they can be converter
@@JamesWestVideo Yea. They're all 19.5v, so can all be converted. I've been running the WD756 in my van for weeks.
@@wherehasthedaygone how are you running it? straight 12v or converted to 19v?
Thanks for this, always wondered if its possible, i have an old CELLO 12v TV in the van and have always hated it, im going to give it a try, ordered the converter today and the smart LG TV. Ill let you know how i get on.
Great have you ordered the 5A converter. just make sure you get all the polarity correct and fit a fuse and you should be fine.
@@BrackstonesTravelAdventures Yes I ordered the same one you used, I have an inline fuse for the converter feed that goes out to the TV.
@@BrackstonesTravelAdventures Not been able to get it to work. LG 24TN520S, 19.1 coming out of the converter, testing it before plugging in. Plug in the TV cable, red light comes on, then nothing when switched on from the remote. Disconnect and Re-test the converter, voltage jumping round all over the place then settles on 10.2? Tested all continuity of the wires, no fuses have blown. Bad converter? or i sorted all the settings before putting it in the van, i set it on one of the power saving modes, could this be a problem?
@@christopherjamesmulholland4533 sounds like bad converter or a loose connection thw converter should always be 19v if it drops at converter output when tv on then converter issue. If its dropping at tv end but ok on converter output then loose connection. I assume you are running this of your leisure battery which is in good condition
thanks @@BrackstonesTravelAdventures going to keep at it, think it might be a connection issue somewhere, or converter, batteries are all good.
Amazing video me friend🤗. Could I ask if anyone would know if I could use a firestick on the TV. Much appreciated
Yes you could run the firestick of the TV USB supply, if this causes problems with the firestick running which I had once then supply the firestick from a 12v USB outlet
Hi ~ did you look at the output of that converter on an o-scope ?
I’m wondering how much ripple it has. 🙂
I did a test on it yesterday and there was no ripple. I would upload a vid/pic but cannot do it on comment.
When you said; ive managed to lower the power of the Tv do you mean in the settings. Or just by making up a 12v lead and using that.?
Not changed any setting within the TV. For the older LG model LG 22MT44D in the Vlog I just connected the 12v direct to the back of the TV. For the Smart LG model LG 24TN520S I bought a 12v - 19V DC - DC converter, I had to get a larger 5A one as the smart part of the TV pulls a lot more power. Link here for this converter www.ebay.co.uk/itm/184360001587
Hi I tried the link for the converter in your description but it is no longer found, you say to use a 5a converter but after looking at the numbers on the converter you show in the video it is clearly a 3a converter, so I guess you used a different converter than the one in the video? also I wanted to ask how good the EPG on Freesat is on the 24TN520S I already have a 19" Avtex TV in the motorhome but the EPG is useless on satellite and only good on Freeview.
If you go ebay search 5a 19v converter. This is about 95w converter on the output. I have tried the smaller 2a ones which work ok on none smart tvs but with the smart processors you need more power. The 5a 90+ watt ones work great been using over a year with no issues
Hello, did you ever get kodi installed on the 24inch smart TV ? was it vanilla android OS ?
I don't think I tried in end, I can play TV and movies straight from my 1Tb USB hard drive. I did not setup kodi as I would have to keep it maintained with the USB hard drive library. But lately I have a lot more shows so was thinking of doing this now getting Kodi to update meta data when at home on wifi so if we are in a black spot we will still have movie/tv meta for the info of the show. i will let you know if i get this done this week
Hi. So do you actually need to use the black adapter that comes with the tele or is that now surplus.. I’m looking to do this in my truck. I have the same tele. Cheers
The black adapter is only used when you are pluggin into the 240V. This converts the voltage to 19V for the TV so no you dont need it unless you want to bring the TV indoors some times.
I cut of the lead from the black adapter and use this from the dc dc converter
Great video, any idea how I could do a 32''' Samsung Frame? It has a full external unit with hdmi and power etc and a single power cable with fancy connection to the tv.. Only uses28-50w Peak. Dont want to use mx 2000x inverter for 28w,, was thinking DC-DC converter to existing cable with plug cut off? Thanks
Hi @RichieKeane if the TV has an external power unit which converts the AC inout into a DC output then it should easily run on a DC DC converter. Find out what the DC output of the TV is and then get a DC DC converter which has a larger wattage than the TV runs on. You will need to use the original TV plug input cable and make sure you have the polarity correct.
@@BrackstonesTravelAdventures That's what I'd hoped...
Do you have the model number for the 22” LG Smart that runs directly from the 12v?
I used the LG 22MT44D its an old 22" none smart TV which should run on 19V but i managed to get it to run happy on 12V. Not many around now and not sure the new smart 22" will run on 12V may need the 19V converter
@@BrackstonesTravelAdventures thank you
Hi I jusst bought the LG 22TN410V The adapter supplied reads "Output 19V 1.7A 32.3 W" I cant find a converter with those exact specs. Will a higher wattage one like a 5 watt do any damage?
Yes thats ok. The higher wattage will be better for the TV to run the smart processing. We have a 5A 95 W converter. The higher amps/watts will not do any damage only high voltage will be a problem so as long as it's 19v you will be fine. I should have a new Vlog this week showing what I have connected up
@@BrackstonesTravelAdventures Thanks for the reply. What size cable did you use from the fuse box to the converter and what size fuse would you recommend?
My TV supply was fitted by dealer to the cupboard, would be about 1.5mm flex for length. From there to the TV I used 1mm flex very short run.
The box on that cable contains a Switched-Mode Power Supply (SMPS). The first component of an SMPS is a rectifier. The rectifier’s roll is to convert AC to DC. Other components after the rectifier “massage” the power to the required VA for the device.
If you send VDC down the rectifier instead of VAC, the entire device will begin heating up at a rate determined by Jen’s Law, and destroy the Earth.
Or it will actually do nothing. I have a difficult time remembering which since I just made up Jen’s Law, and haven’t yet assigned it any properties.
So based on the assumption that Jen’s Law will turn out to be garbage, and knowing there are no other scientific reasons to think otherwise, it’s probably safe to cross our fingers and believe that the low voltage DC will pass through the rectifier and be “massaged” just the same as DC power that passed through the rectifier which so recently possessed enough AC-like properties to be called AC power.
Could you fit a larger TV and run off battery ?
Only if you know what you are doing. Anything over 24" TV will probably require more voltage than 19v so removing the back you may find it can run on 33V, but this is a gamble as large TV's are very power hungry with the lighting and this can be running on higher voltages. I have only done this on the TV's with the 19V power packs same as laptops
What kind of amp draw are you getting
with just the Dc-DC switch on not TV the initial start up is .05 A for about a min then it drops to 0.01A. With the TV on it pulls 1.9 Amps
Any chance you tried this with 24v on the older TV?
If you mean 24V battery to the 19V tv then any DC converter from 24V to 19V will work like this link carlightbulb.com/products/waterproof-24v-to-19v-10a-190w-step-down-dc-dc-power-converter-regulator?currency=GBP&variant=42881950875810&Google%20Shopping&stkn=d7752ef57dbc&gclid=Cj0KCQiAsburBhCIARIsAExmsu6m1MstBOs6awgtc0XKWBe2KzmTZSj_6j7s4gbb9m0ruofgrdG3uYgaAroREALw_wcB
Hello just got a Samsung t22e390ew tv ( 14v - 2.5A) will this run directly with the cigarette lighter conversion or will I need an Converter Regulator ? subscribed thanks for ur great work
I would say it will run direct off the battery. Unusual voltage and with 2.5A might want to look at a better connection that cigarette lighter as this will get hot. Remember a fuse online and if it keeps turning off then look on ebay for 14v converter. Also double check cable polarity before connecting to battery
@@BrackstonesTravelAdventures Samsung t22e390ew tv --- Fused and working great off of 12v
@@Drezzic Thats great another one to add to the list. Is this a Smart TV and does it run all ok running on-demand TV
@@BrackstonesTravelAdventures No just found out it dont work with "dvbt2 - Freeview " not smart but i have a firestick and 5g in my van.. plus you can plug a hard drive or usb.. will look for a better option in the 2nd hand shops.. will do for now.. I'll keep you posted.
@@Drezzic this will be same as my LG TV. Not smart these work OK direct on the battery. Its when it's a smart TV that you need the dc converter as they use more power. You should be fine with a firstick. Glad it's working lot cheaper than a Avtec tv
hello i tried to do this with a hp monitor that runs on 12v dc ( with a wall pack) but when hooked up to my camper battery ( between 13.3 and 12.3v) it just shuts off and on and isnt stable, i figured because it wasnt a stable 12 v dc.... but after afew youtube vids im thinking maybe its my wiring job or the cigarette lighter plug im using... ill have to try again... because now its 12 v dc converted to 120 v ac then back to 12 v dc seems like a bad idea :)
Hi. Yes current is a big issue with keeping displays on. If your wiring is really small and your pulling a lot of current through the cigarette lighter plug then the voltage drop will be high and cause your screen to turn off. Why are you using a computer monitor can this show normal TV. And what is the power wattage of the monitor. I assume it can run on 12v or are you using a converter to 19v
@@BrackstonesTravelAdventures hello thanks for response sir. I'm using a pc monitor because it's what I found at goodwill for 10$ that was DC . And it works great for DVD or xbox but true no TV reception. It's ok though because I go weekends in backcountry Ontario canada and dont need reception. The wire from the cigarette lighter plug (also goodwill, 2$) has very thin wiring but it's for 12v . And the monitor only pulls 50watts.. I will run thicker wire for plug and do some multi meter testing and see what's up. Be cause I think it's a great idea if I can just get it working. The monitor is LCD and is 20 inch so I would love to get it working without using my inverter and wasting those precious amp hours.😀 and yes the moon itor is for 12 volts, as I use a 12 v wall pack to power it, and it's written on the back
So it's pulling just over 4 amps. If it's a 12v monitor then it should work with no issues. If it's a 19v and your using a converter then you will need one rated a lot higher than 50 watts. I would look at an 8 amp converter. See what happens when you upgrade the cables. Good luck
@@BrackstonesTravelAdventures sub earned sir😀
@@uncle_creepy2743 ha ha thank you
This may sound stupid but can I ask , does the 24” tv no longer need the power box due to the converter unless your back on using 240v?
Yes that is correct the convert runa the tv. I keep the main power supply in the van for backup
@@BrackstonesTravelAdventures thanks a for the info
Today I’ve put up a lg 28” in my van so thinking I’ll need one of the 12v-19v converters you’ve used as on the power box it’s putting out 19v @ 2.1 amp.
@@CASHO76 If it has 19v then it should run on a DC DC converter ok, you will need at least 45w one but may be best to go 50W if you can get one
Sorry to be a pain. I saw this on Amazon 200W Car Power Inverter, LEICESTERCN DC 12V to 230V AC Car Inverter 4 USB Ports Charger Adapter Car Plug Converter with Switch. You think this would work or will it drain the battery to quick?
Hello mate how big is your battery I'm looking to run a 110 amp with a solar set up day time but when off grid do you think it would last a few hours with out draining the battery?
Hi. I have lithium as they give 100% of there capacity and charge at a higher rate. The TV will pull about 3A so for 3 hours this will be 9aH. Take into account lighting maybe 3A and water pump. Then add anything else you may use. If the 110aH battery you have was at 100% charge then you have about 50aH of use. But without a battery shunt how would you know the charge state of the battery.
@@BrackstonesTravelAdventures that's probs enough hours in the evening anyways it's only occasionally that it will be on the 12v most the time will be on sites with EHU the van has a split charge relay system now was thinking of putting a 100amp solar setup aswell
Do you know any 32 inch TVs that could be converted?
No, I only did the 22" I will have a look at teh TV's I have in the house see what they run on tomorrow

Hi, just tried with LG 24TQ510S-PZ 24 Smart tv with the same xw 12-19-57w 3amp set up in video... It doesn't work🤔
Have you checked all the connection for any loose one. someone had similar a year ago. Also if you have a meater can you check the voltage coming out the converter. Another thing to check that the polarity is the same as the original TV supply.
another thing the 3 amp converter may not be powerfull enough to turn on a 24" TV. Does the red light come on but no screen powering up. If no connection issues you may need a 5A converter. If you put a voltmeter on the converter output whist connected to the TV you may see the voltage drop off as you turn in the TV indicating the converter is not power full enough
@@BrackstonesTravelAdventuresThaks for replies..checked connections and they're OK swapped converters also as I bought 2. Light on tv doesn't come on at all. Power from supply is OK, I don't have a tester. Do you think I need a 5A 95w?
Its possible, When I did my TV the smaller 3A converters would not power them up or would try to turn on then shut down again. Most larger TV with smart systems use a lot more power
@@BrackstonesTravelAdventures OK will give it a go and post result
So can I buy a 32" smart TV and do the same conversion? If yes, you've just saved me from buying the Avtec one for 500 quid 😅
Ive never done a 32" tv it will only work n TV's with a 19V power supply into it, I have herd that some TV's at 32" have this but I have not seen one myself. Someone has just done a 32" monitor which if this has a HDMI input this can then take a Amazon firestick
@@BrackstonesTravelAdventures OK I will try and source one that's 19v
