convert a tv to 12 volts

[@loafandjug321]

Tip: Find a TV that you like, then Google search the model number for a replacement circut board image. That lets you see theTV board before buying.

[@yellowcreeklife7801]

That is a very good idea. Thanks for the tip

[@Elfnetdesigns]

1. This is not easily done on most TV sets now and you will need to know where to look on the PCB for a spot to tap on to if such a spot exists for 12 volts. 2. Maybe put a diode inline of the positive to prevent backfeeding voltage up the 12 volt lead while using 120 volts. 3. You should put a protective grommet or strain relief on the cable where it enters through the metal chassis.

Good to know, I would try this for sure 👍👍👍 I would just recommend to avoid all theses little chunks of metal from the drilling to get to the PCBs and connections 😅 😛 I 'd rather pierce a hole into the plastic casing then in the metallic support...

[@Teknopottu]

True words. 12V cable would also last longer and be safer than grinding against metal.

[@cheapme1850]

Thanks! Worked perfectly on my Insignia NS-19D310NA19, 19” TV. The only thing I did differently was to run the power cord out of the side, parallel to the AC cord. I also wish I had used a cord longer than the 1 ft that I used. Btw, you need a 2mm JST connector.

[@rayreyes5405]

Great info. I have an old 32" Hisens that I would like to make 12V for my RV. Hope it has a similar board in it.

[@Elfnetdesigns]

32" is hit or miss for 12 volt operations and this is due to the backlight arrangement and voltage requirements for the driver circuit to work properly. They may flicker or not reach full brightness and because they are starved for current they will cause premature failure of the driver filter caps and deprive other circuits proper voltage and current which can cause undesired operation.

[@RichardGottardo]

doesn't work on Vizio 32" D32f-J04 .. power light flashes but screen doesn't turn on.. seems like LED driver is powered separately

[@yellowcreeklife7801]

Yes I have noticed that. there’s a video where the transformer is removed and done that way haven’t tried it yet

[@Elfnetdesigns]

Not enough current to start the driver SMPS that run the LEDs

[@owenbruce4120]

​@@ElfnetdesignsI used an adjustable micro boost converter tapped of a 12v rail...on a Teco 32"... it's been working great for 5+ years...have to set backlight brightness to taste

[@lakestatebullies7391]

Doing this to a insignia tv. Looks identical to the one your doing. You should really put a regulator for the voltage.

[@cheapme1850]

I figured that since it says 12v on the circuit board, no regulator is needed.

[@gtstanton9785]

Where do you get the micro plug from? I think you said JS10

[@johnlucier8572]

Doesn't vacuum the board and bingo a short is born. I cannot believe it.

[@yellowcreeklife7801]

Yeah should have shown that part. I used an air hose to blow out shavings

[@clevonpereira9145]

Great info dude ❤

[@AsYouWishPhoto]

What's the size of that plug I bought the jst micro plugs from Amazon and there really small..any help would be greatly appreciated.

[@mrsuarez430]

You can just get an inverter but regardless good video usefull as inverter step up will use up a bit more power than directly to 12 like this

[@ralphmoulph1256]

Inverters idle more power than TV's

[@sulenebankston3694]

Can.you.splice the wires together or do the have to be soldiered

[@davidmacphail4048]

I realise this an old video but did anyone open the back and find that their plug had 4 pins instead of 2? Two marked 12 volt and two marked ground? Any help appreciated

[@bubbahyid0]

thank you

[@chizxyclearmonei9471]

Didn’t work on my power comes up but screen is blank

[@tombuderer8290]

where did you get the jst plug to insert into the tv?

[@SONNYemc]

Thanks a lot

[@BienviTv]

Liget 12v what amper do you use 12v

[@kb5zcs]

Where did you get the JST micro plug from......

[@Elfnetdesigns]

ebay or some cheap old battery powered bluetooth thing or air ionizer, older toys. hover boards, old CRT TV sets, old stereos, VCRs...

[@ibrahimitob9834]

thank u

[@julienguerre9218]

Hello everyone !!! Does anyone have a reference or link for the connector? Thanks a lot

[@yellowcreeklife7801]

eBay has the JST micro plug

[@gavinsmith2656]

Do you need a fuse between the battery and the tv?

[@yellowcreeklife7801]

Yes most of your 12v plugs have one in it

[@talentoytrabajo2880]

Mostro todo lo de aserla funcionar con 12 voltios es lo de menos pero no enceño como ISO para iluminar las regletas led como las alimento

[@TaminusAqua-vy6ij]

I did same thing to my Hisense 32 inch TV and it shows just the red light but never turns on.. What's wrong please I need a response

[@yellowcreeklife7801]

Yeah that one is a problem it has separate power for the screen not sure how to fix that

[@PekamoTheAceMech]

I ran into this same issue and figured that the TV is actually displaying picture if you flash a torch closely on the screen. Meaning that the power upgrade connector doesn't power the backlight. However, there's a 2 pin connector at the backlight driver section at the top of PCB I'm planning to supply with 2.5v to see what happens. The connector isn't in use.

[@PekamoTheAceMech]

Were you able to handle an headway with the backlighting?

[@rayreyes5405]

So this will not work on a Hisense? Well then I'm screwed.

[@babsongee5]

I think the backlight is consume more than 12voltage

[@_liam_1607]

this is not the same tv

[@Corn_bread_]

I hooked the 12v up to my 100mh lithium battery and it didn't work.
