**Operate a LED tv with 12v (for camping, off grid house, track, car)
''also we use the diode for flyback protection '' The black cable (-) is on the PCB's ''ground'' . We need a diode and a fuse up to 5A for this 28''tv**

I just randomly searched for this. Good work!
0:47 PWR UPGRADE plug left of cap.
They make 12 volt TVs you can find them at most big-box stores just start looking at the back of the TVs. You're welcome.
They cost the same as average TVs because they are average TVs, it's just that some TV's already have a 12 v input.
Good to know!
Hi, if I wanted to run a small 12v TV would a couple of car batteries 1 linked to a small turbine and 1 linked to solar, would that be enough to be able to run the TV for 16 - 18 hours a day?
I'm setting up a caravan for an escape, I've worked the lighting and mobile phone charging with the small solar phone charger/torch combos but need to work out a cheap way to run the TV and if possible a 12v fridge, would appreciate any tips, thanks in advance
Now that the power is direct, does the screen light have an amount of hertz?
Normal TV with AC input 220v usually convertes to about 360v dc that then is converted to 12v dc by switching power supply. You can wire a 12 v solar panel to the dc12v position or even a string of panels to the 360dc v position inside tv.
Which tvs? How do I determine where to put the diode and fuse?
Great video! Just two questions:
1.- You just connect 12V in a pin, but what about 3'3V and 5V pins?
2.- Is there a problem if the battery supplies 14V instead of exactly 12V? And what's the lower voltage when the the TV switches off?
Thanks in advance.
Hello!! Thanks!
The output of this TV's power supply is 12v. the 5v and 3.3v is after this power supply, so we don't worry about this..
My battery is 24v and I have a dc to dc converter 24 to 12, the output is 13.7 as a fully charged 12v battery. (Measure the voltage before destroy the power supply)
Thorough.. Must watch.
Super
Did you measure how much current the tv uses on 12V? I’m interested in whether doing this is more power efficient than running from 240V AC
It will be more efficient 😉
240v a.c.!!!!!! Hell, let's just run 600v ac and put in a hot tub worth jets!
@@offgridselfteliant most of europe runs 230-240V AC domestic mains. We’ve all grown up getting shocked, so have nothing to lose apart from our frizzy hairstyles 🤣😂👍
Massa
Je voudrais que vous fassiez une autre vidéo svp
Just to the right and below where it says HOT is a 2 pin socket.that is 12v
Hello!! Not for all TVs..
Pls can u redo this video...I want to try it...but some details are missing
what are the specs on the diode? should it be 12V, or 16v?
The diode must be large enough to burn the 5A fuse to reverse polarity for protection . I think I use a schottky diode 10 A
@@OffGridCrafts you think? Lol nice
10A Schottky and 5A fuse ain't that too high if the fuse is 3.15 A on HT side..
You literally have a 12V connector on the board that says "PWR UPGRADE". Just use that as a 12V supply and all the things you did in the video are unnecessary.
Good tutorial, but its applicable for TVs that don't have a dedicated 12V input.
Hi!! Maybe you are right.. If a tv don't have this connector this solution is ok
you are right. just did it that way and it works. mine is not labeled "PWR UPGRADE" but i took off the board and on the back it said 12v.
Correct
if the capacitor is 25v, i can change it to one of 16 so it can work
no don't change the capacitor, can you measure the voltage?? BE CAREFULL WITH THE HIGH VOLTAGE
I'm not gonna thru all that bullshit, come on man.
